The COVID-19 pandemic in Japan is part of the worldwide pandemic of coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The virus was first confirmed to have spread to Japan in January 2020.[2] Definitively reported cases have been recorded in each of the 47 prefectures except for Iwate. The country has seen over 17,000 confirmed cases.

Japan’s death rate per capita from coronavirus is one of the lowest in the developed world, more than 70 times lower than the UK and 40 times lower than the USA. Scientists have asked themselves what it is about Japan’s response to the coronavirus that has enabled such a low death rate. The government response, a milder strain of the virus, social effect caused by community immunity, cultural habits such as bowing etiquette or wearing face masks, hand washing with sanitizing equipment, a protective genetic trait, and a relative immunity conferred by the mandatory BCG tuberculosis vaccine[3] have all been proposed as possible explanations.

The Japanese government confirmed its first outbreak of the coronavirus disease 2019 (COVID-19) in the country on 16 January 2020 in a resident of Kanagawa Prefecture who had returned from Wuhan, China. This was followed by a second outbreak that was introduced by travelling passengers and returnees from Europe and the United States between 11 March and 23 March.[4] According to the National Institute of Infectious Diseases, the majority of viruses spreading in Japan derive from the European type while those of the Wuhan type have been disappearing since March.[5][6]

The Japanese government has adopted various measures to prevent and mitigate the outbreak. On 30 January, Prime Minister Shinzo Abe established a national task force to oversee the government's response to the pandemic.[7] On 27 February, he requested the temporary closure of all Japanese elementary, junior high, and high schools until early April.[8]

On 11 March, it was announced that Tokyo Disney Resort and USJ are extending their closure until further notice due to request of society.[9] On 16 March, it was confirmed that almost 70% do not expect Tokyo Olympics to be held as scheduled.[10] As the pandemic became a concern for the 2020 Summer Olympics, the Japanese government and the International Olympic Committee negotiated its postponement until 2021, although complete cancellation is not out of the question.[11]

On 7 April, Abe proclaimed a one-month state of emergency for Tokyo and the prefectures of Kanagawa, Saitama, Chiba, Osaka, Hyogo, and Fukuoka.[12] On 16 April, the declaration was extended to the rest of the country for an indefinite period.[13]

Some medical professionals and media outlets have criticized the Japanese government for under-testing for COVID-19.[14][15][16]

On 14 May, Japan released the registry to relieve the nationwide state of emergency COVID-19 in 39 of Japan's 47 prefectures or 54% of Japan's population, but it still applied in Tokyo, Osaka, Kyoto, Hyogo, Hokkaido, Chiba, Kanagawa, and Saitama.[17][18]

On 21 May, Japan ended the state of emergency in Osaka, Kyoto, and Hyogo prefectures.[19][20]

On 25 May, Japan ended the state of emergency in all of Japan.[21]

Data sourced from Japan Ministry of Health, Labour and Welfare and World Health Organization, as reported from 10:00|CET on the day to 10:00|CET on the following day (18:00|JST on the day – 18:00|JST the following day).

The 2020 coronavirus pandemic in Japan can be divided into two waves based on the genome sequence of the country's COVID-19 virus.[22][5][6][23] The National Institute of Infectious Diseases (NIID) has determined from its genetic research that the COVID-19 variant of the first wave is derived from the Wuhan type that is prevalent in patients from China and East Asia. After entering Japan in January through travellers and returnees from China, the virus resulted in numerous infection clusters across the country before moving towards its disappearance in March. Japanese medical surveillance confirmed its first case of the virus on 16 January in a resident of Kanagawa Prefecture who had returned from Wuhan.[24][25]

The first wave was followed by a second one that originated from a COVID-19 variant of the European type that is traced back to early patients from France, Italy, Sweden, and the United Kingdom.[5][23] Japanese medical surveillance detected the second wave on 26 March when the government's expert panel concluded the likelihood of a new outbreak caused by travellers and returnees from Europe and the United States between 11 March and 23 March.[4] The NIID has established that the majority of viruses spreading in Japan since March is the European type. This has led it to conclude that the data "strongly suggests" that the Japanese government has succeeded in containing the Wuhan variant and that it is the European variant that is spreading across the country.[26]

First wave (January–March)[edit]


On 16 January, Kanagawa Prefecture confirmed its first case of COVID-19 when a man in his 30s who had previously travelled to Wuhan tested positive for it, marking the first confirmed case in Japan.[25][24]

On 24 January, Tokyo Metropolis confirmed its first case of COVID-19.[27] The Japanese government announced that it would provide repatriation services for all Japanese citizens in Hubei Province on that same day. Officials negotiated with Chinese authorities to dispatch five chartered flights to Wuhan from 29 January to 17 February.[28]

On 27 January, Prime Minister Shinzo Abe designated the novel coronavirus as an "designated infectious disease" under the Infectious Diseases Control Law. He also designated the disease as a "quarantinable infectious disease" under the Quarantine Act.[29] On 30 January, Abe announced the establishment of a national task force to oversee the government's countermeasures against the novel coronavirus.[30][7]

On 28 January, Nara Prefecture and Hokkaido Prefecture confirmed their first cases of COVID-19.[31][32] On 29 January, Osaka Prefecture reported its first case on January 29,[33] followed by Mie Prefecture and Kyoto Prefecture on 30 January,[34][35] and Chiba Prefecture on 31 January.[36]


On 1 February, a passenger of the Diamond Princess cruise ship who had disembarked in Hong Kong on 25 January tested positive for COVID-19.[37] The ship received quarantine orders from the Japanese government in Naha on that same day.[37]

On 3 February, the Japanese government announced entry restrictions for all foreign citizens who had had a travel history to and from Hubei Province or had a Chinese passport issued from there.[38] The Diamond Princess arrived at Yokohama and was placed under quarantine by the Japanese government on the same day.[39][40]

On 2 March, nearly all prefectures began shutting schools Monday in a bid to prevent the further spread of the coronavirus in Japan, four days after Prime Minister Shinzo Abe surprised many with a request for schools to be closed countrywide until early April.[67] By paying up to 8,330 yen ($77) a day per worker for paid leave between Feb. 27 and March 31, the ministry hopes to help companies compensate workers for income losses.[67] Furthermore, the criteria for employment subsidies have been eased for those that have been affected by the pneumonia-causing virus to include non-regular employees as well.[67]

On 4 March, The Japan High School Baseball Federation said Wednesday it is preparing to hold the national high school baseball invitational tournament behind closed doors due to the spread of the new coronavirus, while also mulling possible cancellation of the meet.[68]

On 5 March, Japan announced quarantine restrictions for all visitors arriving from China and South Korea.[69] On 6 March, the South Korean government protested the restrictions by suspending visas for all Japanese citizens travelling to South Korea.[70]

On 6 March, Some e-learning program providers are offering their services for free to help students keep up with their studies while schools in Japan remain closed over the coronavirus outbreak.[71] Major comic book publishers, meanwhile, are taking the same step to keep students entertained, with the government calling on students to remain indoors before schools reopen in early April at the earliest.[71]

On 10 March, Japan on Tuesday adopted a fresh 1 trillion yen ($9.6 billion) level emergency package for businesses battered by the new coronavirus outbreak, featuring 500 billion yen in zero-interest loans for small and midsize companies short of cash due to sharp falls in sales.[72] The stimulus measures, which entail 430.8 billion yen in actual spending under the fiscal 2019 budget, also include providing 4,100 yen a day in subsidies for freelance workers who are forced to give up work to take care of their children amid school closures following the outbreak.[72]

On 10 March, the Japanese government categorized the 2020 coronavirus pandemic in Japan as a historical emergency situation.[73][74][75] Additionally, Prime Minister Shinzo Abe on Tuesday requested that big sports and cultural events in Japan be canceled or postponed for 10 more days as the government needs more time to gauge the effectiveness of its measures to contain the new coronavirus.[76]

On 13 March, Saga Prefecture confirmed its first case of COVID-19.[77] Nagasaki Prefecture reported its first case on 14 March,[78] followed by Ibaraki Prefecture[79] and Kagawa Prefecture[80] on 17 March, and Fukui Prefecture on 18 March.[81]

On 16 March, the Japanese government announced it would expand entry restrictions to all foreign citizens arriving from four additional countries. The restrictions applied to three areas in Spain (including Madrid), four areas in Italy (including the northern region of Liguria), Switzerland's Ticino region, and all of Iceland.[82]

On 19 March, the governors of Osaka and Hyogo prefectures asked residents to avoid nonessential travel between the two neighbouring prefectures over the three-day weekend starting on 20 March to contain the spread of the coronavirus.[83][84] The three-week state of emergency in Hokkaido was lifted on that same day.[85]

On 22 March, Okayama Prefecture confirmed its first case of COVID-19 and requested its residents to refrain from visiting the neighboring prefectures of Hyogo and Osaka.[86][87] Aomori Prefecture reported its first case on 23 March,[88] followed by Gifu Prefecture on 26 March.[89]

On 23 March, Tokyo governor Yuriko Koike warned residents that a lockdown might be the only way against the disease if infections were to surge in Tokyo as she urged people to cooperate with government countermeasures.[90][91][92]

On 24 March, the International Olympic Committee (IOC) and Tokyo Organising Committee of the Olympic and Paralympic Games announced a one-year postponement of the 2020 Summer Olympics.[93]

Second wave (March–present)[edit]


On 25 March, MHLW officials announced 71 people tested positive,[94] including 41 cases in Tokyo.[95] Governor Yuriko Koike held an emergency press conference in the late afternoon. She said that "the current situation is a serious situation where the number of infected people may explode." Koike also asked "if possible, work at home and refrain from going out at night as much as possible on weekdays." Koike asked people returning from abroad to refrain from going out for 14 days.[96] The request from the governor appears to have punctured the relaxed mood in Tokyo. Panic buying began to trend on Twitter, with users posting pictures of empty shelves and lines outside supermarkets. At the Don Quijote store in Nakameguro, customers hurried to grab instant noodles and canned goods immediately following Koike's late-evening speech.[97]

On 26 March, several governors of the Greater Tokyo Area, including Chiba, Kanagawa, Saitama, and Yamanashi, strongly urged residents to follow stay-at-home requests to prevent a surge in infections that could cause a "critical phase".[98] In Tokyo, residents were asked to work from home and refrain from going out at night and on the weekend.[99]

On 27 March, MHLW officials announced 112 people had tested positive in a single day, including three Hanshin Tigers professional baseball players.[100][101]

On 28 March, Abe held an hour-long press briefing about the economic measures being prepared by the Japanese government[102][103] amid considerable concerns of an "explosive spread of overflowing infections", which was creating regional self-isolation requests around Japan, including in Tokyo, Osaka, Hyogo, and Aichi.[104] Abe's wife became the centre of controversy when she was accused of attending a hanami party during the pandemic. Abe denied the claim and said she merely took pictures in front of some cherry trees after going to a restaurant.[105]

On 29 March, MHLW officials announced 194 people had tested positive for the virus, including 58 people at a facility for the disabled in Tōnoshō, Chiba Prefecture, and 63 in Tokyo.[106] However, a Tokyo municipal government official acknowledged by the end of the day that 63 people in the city tested positive for COVID-19 on 28 March and that a record number of 68 people tested positive on 29 March.[107] It was also revealed that Tokyo now had 430 confirmed cases of COVID-19, the largest among Japan's 47 prefectures.[107]

On 30 March, it was announced that tarento and comedian Ken Shimura had died at the age of 70 from complications of a COVID-19 infection. This marked the first major death from the pandemic in Japan's entertainment industry.[108][109][110]

On 30 March, Fukuoka City announced confirmed cases in a woman in her 20s and her infant daughter.[111] On 30 March, Toyama prefecture announced its first case,[112] and a Kyoto government official announced that the Kyoto Sangyo University had undergone "a cluster of infections"—including two students who had recently returned from travel to Europe.[113][114][115]

By 31 March, calls were being made for Abe to declare a state of emergency.[116][117] However, Abe and Chief Cabinet Secretary Suga denied that a state of emergency was immediately necessary.[118]

As of 31 March, Tokyo on Tuesday reported a record daily increase of 78 new infections, raising its total to 521.[119] Of that number, 10 cases are from what authorities believe is a cluster infection at Eiju General Hospital in Taito Ward.[119] Tokyo reported seven deaths among infected residents Tuesday.[119]

On 1 April, The government established Wednesday a team within the secretariat of the National Security Council tasked with crafting Japan's strategic response to the coronavirus crisis while improving its competitiveness in the technology and economic spheres.[120] Specifically, the team is planned to focus on overcoming the novel coronavirus epidemic as well as driving Japan's development in the fields of artificial intelligence and 5G wireless, especially in the face of the United States' and China's race for supremacy in the technologies.[120]

The Immigration Services Agency of Japan said Friday it will extend for three months the deadline for foreigners to renew their period of stay in a bid to alleviate congestion at immigration counters amid the coronavirus outbreak.[121] At present, immigration counters nationwide are crowded with foreigners, including short-term stayers, who are applying for extensions of their stay in Japan, with some of them unable to return home due to tighter border control across the globe.[121]

On 3 April, Japan expanded its entry ban, effectively barring entrance to the country for visitors from 73 countries and regions.[122]

On 4 April, at least 118 new coronavirus cases were confirmed in Tokyo on Saturday, the first time the daily increase has topped 100, the metropolitan government said, in a development that could raise pressure on Japan to declare a state of emergency.[123] Prime Minister Shinzo Abe had been widely seen as cautious about declaring an emergency despite spiking infections in urban areas like Tokyo and Osaka and growing calls from medical experts to do so due to fears the country's health care system could collapse.[123]

On 6 April, The Tokyo metropolitan government on Monday reported 83 new coronavirus cases following two days of three-digit increases, as it continues to grapple with a recent spike in the number of infections.[124] The metropolitan government planned to begin transferring patients with mild or no symptoms from hospitals to designated hotels and other lodging facilities on Tuesday as it wants to prioritize treatment for patients with severe symptoms.[124]

On 7 April, Abe proclaimed a state of emergency from 8 April to 6 May for Tokyo and the prefectures of Kanagawa, Saitama, Chiba, Osaka, Hyogo and Fukuoka. He also said there would be no lockdown like in other countries, and that public transportation and other services needed to keep the economy and society going would be maintained as much as possible.[125] This was the first emergency declaration in Japan.[126][127] Abe also stated that the pandemic had created the nation's greatest economic crisis since the end of World War II.[13]

On 8 April, Tokyo confirmed 144 new coronavirus infections Wednesday, a record daily high, metropolitan government officials said.[128] Of the 144 infections confirmed Wednesday, 95, or more than 60 percent, had no clear infection routes, the officials said.[128] The total number of infections confirmed in Tokyo now stands at 1,338, with 1,231 people hospitalized and 35 deaths from the pneumonia-causing virus as of Tuesday evening.[128]

The number of people infected with the new coronavirus was also confirmed in Kyushu on July 5th.[297] Kagoshima Prefecture has confirmed 13 men and women in their teens and 50s.[297] They were both visitors and contacts at a show pub in Kagoshima, where clusters were believed to have occurred.[297] Nine new infections have been confirmed in Fukuoka Prefecture.[297] Four of the men and women in their 20s and 50s in Fukuoka are members-only snacks in Fukuoka, where customers and employees have been confirmed to be infected.[297] A total of seven people were infected with the shop, two employees and five customers, and the city believes a new cluster has occurred.[297] This is the seventh case of cluster outbreak in the city.[297] In Miyazaki, men in their 40s were also confirmed to be infected.[297] It has been confirmed in Miyazaki Prefecture since April 11.[297]

On 6 July, 176 new cases of the new coronavirus were confirmed in Japan.[298][299][300] The number of new infections in Tokyo was 102, exceeding 100 for the fifth consecutive day.[298][299][300] In addition, there were 16 people in Saitama, 11 people in Kanagawa, and 12 people in Kagoshima.[298][299][300] At the same day, revamped government expert panel gave the go-ahead to the plan to take a further step away from emergency mode, on the premise that preventive measures against the virus are taken, said economic revitalization minister Yasutoshi Nishimura, who is in charge of the government's coronavirus response.[301][302]

On July 7th, 106 new cases of the new coronavirus were confirmed in Tokyo, according to a report from the Tokyo metropolitan government.[303] The number of people infected per day in Tokyo exceeded 100 for the sixth straight day, and the average number of people infected per week exceeded 100.[303] In response to the increase in the number of people infected in Tokyo, Yuriko Koike asked Tokyo residents to refrain from moving outside the city without any urgent need since July 4th.[303] According to a summary article of nationwide infected peole in the Mainichi Shimbun, 214 new coronavirus cases were confirmed nationwide on July 7.[304] There are 20,866 people infected in Japan, including cruise ship passengers.[304] One person died in Saitama and Chiba prefectures, with a total of 993 dead.[304] Recent cases of infection in Tokyo are not only related to downtown areas in their 20s and 30s, but also have many cases where routes are unknown.[305] On July 7th, there were 27 new infections in Saitama, 12 people in Osaka, 11 people in Chiba, 9 people in Kanagawa, Kyoto and Kagoshima.[305]

Government response[edit]

Phase 1: Containment[edit]

The initial response of the Japanese government to the COVID-19 outbreak was a policy of containment that focused on the repatriation of Japanese citizens from Wuhan, the point of origin of the pandemic, and the introduction of new border control regulations.[28]

On 24 January, Abe convened the Ministerial Meeting on Countermeasures Related to the Novel Coronavirus at the Prime Minister's Office with members of his Cabinet in response to a statement by the World Health Organization (WHO) confirming human-to-human transmission of the coronavirus. Abe announced that he would introduce appropriate countermeasures to the disease in coordination with the National Institute of Infectious Diseases (NIID).[306]

On 27 January, Abe designated the new coronavirus as an "infectious disease" under the Infectious Diseases Control Law (感染症の予防及び感染症の患者に対する医療に関する法律), which allows the government to order patients with COVID-19 to undergo hospitalization. He also designated the disease as a "quarantinable infectious disease" under the Quarantine Act, which allows the government to quarantine people suspected of infection and order them to undergo diagnosis and treatment.[307]

On 30 January, Abe announced the establishment of the "Novel Coronavirus Response Headquarters" (新型コロナウイルス感染症対策本部), which meets at the Prime Minister's Official Residence and is run by a task force led by Deputy Chief Cabinet Secretary for Crisis Management Okita Yoshiki.[30][7] The initial roster of the task force includes 36 high-ranking bureaucrats from several of the Ministries of Japan. The headquarters acts as the site of Abe's decision-making process on the country's virus countermeasures.

On 31 January, Abe announced that the government was prioritizing the repatriation of Japanese citizens from Hubei province. Officials negotiated with Chinese authorities to dispatch five chartered flights to Wuhan from 29 January to 17 February.[28]

On 1 February, the Japanese government enacted restrictions to deny entry to foreign citizens who had visited Hubei province within 14 days and to those with a Chinese passport issued from there.[308] On 12 February, it expanded those restrictions to anyone who had a recent travel history to and from Zhejiang province or had a Chinese passport issued from there.[43]

On 5 February, Abe invoked the Quarantine Act to place the cruise ship Diamond Princess under quarantine in Yokohama. Quarantine officers were dispatched to the ship to prevent the disembarkation of crew and passengers, and to escort infected patients to medical facilities.[309]

On 6 February, Abe invoked the Immigration Control and Refugee Act to deny entry to the cruise ship MS Westerdam from Hong Kong after one of its passengers tested positive for COVID-19.[310]

Reinforcement of medical service system[edit]

Prime Minister Shinzo Abe convening the first Novel Coronavirus Expert Meeting on 16 February 2020

After the COVID-19 outbreak on the cruise ship Diamond Princess, the Japanese government shifted its focus from a containment policy to a prevention and treatment one because it anticipated increasing community spread within Japan. This policy prioritized the creation of a COVID-19 testing and consultation system based on the National Institute of Infectious Diseases (NIID) and the government's 83 existing municipal and prefectural public health institutions that is separate from the civilian hospital system. The new system handles the transfer of COVID-19 patients to mainstream medical facilities to facilitate patient flow, triage, and the management of limited testing kits on their behalf to prevent a rush of infected and uninfected patients from overwhelming healthcare providers and transmitting diseases to them. By regulating COVID-19 testing at the national level, the Abe Administration integrated the activities of the national government, local governments, medical professionals, business operators, and the public in treating the disease.[307]

On 1 February, the Ministry of Health, Labour and Welfare instructed the municipal and prefectural governments to establish specialized COVID-19 consultation centres and outpatient wards at their local public health facilities within the first half of the month.[311] Such wards would provide medical examinations and testing for suspected carriers of the disease to protect general hospitals from infection.[311]

On 5 February, Abe announced that the government would begin preparations to strengthen COVID-19 testing capabilities at the NIID and 83 municipal and prefectural public health institutions that are designated by the government as official testing sites. Without a uniform diagnosis kit for the disease, the government has relied on polymerase chain reaction (PCR) tests to check for infections. As few mainstream medical facilities in Japan can conduct PCR tests, Abe also promised to increase the number of institutions with such kits, including universities and private companies.[309]

On 12 February, Abe announced that the government would expand the scope of COVID-19 testing to include patients with symptoms based on the discretion of local governments. Previously, testing was restricted to those with a history of travelling to Hubei Province.[312][313] On the same day, the Ministry of Health and NIID contracted SRL Inc to handle PCR clinical laboratory testing.[314] Since then, the government has partnered with additional private companies to expand laboratory testing capabilities and to work towards the development of a rapid testing kit.[315]

On 14 February, Abe introduced the government's coronavirus consultation system to coordinate medical testing and responses with the public. The Ministry of Health, Labour and Welfare worked with local governments to establish 536 consultation centres (帰国者・接触者相談センター) that covered every prefecture within the country to provide citizens with instructions on how to receive COVID-19 testing and treatment. The general public needs to contact a consultation centre by phone to get tested at one of the government's specialized outpatient wards (帰国者・接触者外来).[316][317]

On 16 February, Abe convened the government's first Novel Coronavirus Expert Meeting (新型コロナウイルス感染症対策専門家会議) at the Prime Minister's Office to draft national guidelines for COVID-19 testing and treatment.[318] The meeting was chaired by Dr. Wakita Takaji, Director of the NIID, who brought together ten public health experts and medical professionals from across Japan to coordinate a response to the virus with Abe and the government's coronavirus task force in a roundtable format. The main concern of the Japanese medical establishment was overcrowding of hospitals by uninfected patients with light cold symptoms who believed that they had COVID-19. Medical representatives claimed that such a panic would strain medical resources and risk exposing those uninfected patients to the disease itself.[319][320]

On 17 February, the Ministry of Health, Labour, and Welfare released national guidelines for COVID-19 testing to each of the municipal and prefectural governments and their public health centres.[321][322] It instructed doctors and public health nurses who staff the consultation centres to limit consultations to people with the following conditions: (1) cold symptoms and a fever of at least 37.5 °C (or need to take antipyretic medication) for over four days; and (2) extreme fatigue and breathing difficulties. The elderly, people with pre-existing conditions, and pregnant women with cold symptoms can receive consultation if they have had them for two days.[321]

On 22 February, Health Minister Katsunobu Kato announced that the Japanese government was looking into the use of favipiravir, an anti-influenza medication developed by Fujifilm, to treat patients with COVID-19.[323][324] The company responded by increasing production of the drug, providing technical support to clinical researchers, and distributing the drug to hospitals where its use has been approved by the government for emergency purposes.[citation needed]

Phase 2: Mitigation[edit]

On 23 February, Abe instructed the government's coronavirus task force to quickly draft a comprehensive basic policy.[325] Health Minister Katsunobu Kato reconvened the medical experts from the first Novel Coronavirus Expert Meeting on 24 February to draft this policy.[326] During the meeting, the medical establishment presented its policy recommendations in the form of a views report (Japanese: 新型コロナウイルス感染症対策の基本方針の具体化に向けた見解), concluding that the most important objective must be the prevention of large-scale disease clusters and a decrease in outbreaks and deaths. They stated that it would not be possible for the government to prevent the spread of COVID-19 in Japan on a person-to-person basis, but that it might be possible to regulate the overall speed of infection.[327] They cited the next week or two as a "critical moment" determining whether the country would experience a large cluster that could result in the collapse of the medical system and socio-economic chaos. After reviewing and discussing the existing data on the disease, the committee stated that universal PCR testing was impossible due to a shortage of testing facilities and providers, and recommended that the government instead limit the application of available test kits to patients that are at a high risk of complications in order to stockpile for a large cluster. Participants also noted that Japan's medical facilities are vulnerable to "chaos," noting that many hospital beds and resources in the Tokyo area were already being used to care for the 700 infected patients from the Diamond Princess. They reiterated their warning that a rush of alarmed, uninfected outpatients with light symptoms of the disease could overwhelm hospitals and turn waiting rooms into "breeding grounds" of COVID-19.[328]

The objective of the Japanese government's basic policies for control is to "flatten the curve".

On 25 February, the Abe Administration introduced the "Basic Policies for Novel Coronavirus Disease Control" (Japanese: 新型コロナウイルス感染症対策の基本方針) based on advice from the expert meeting.[329] After a spike of infections in Italy, Iran, and South Korea, Abe decided that the government's disease countermeasures would prioritize the prevention of large-scale clusters in Japan. This included controversial requests to suspend such large-scale gatherings as community events and school operations, as well as to limit patients with light cold symptoms from visiting medical facilities to prevent them from overwhelming hospital resources.[330]

First, the new policies advised local medical institutions that it is better for people with mild cold-like symptoms to rely on bed rest at home, rather than seeking medical help from clinics or hospitals. The policy also recommended that people at a higher risk of infection – including the elderly and patients with pre-existing conditions – avoid hospital visits for non-treatment purposes, such as by ordering prescriptions over the telephone instead of in person.[328]

Second, the new policies allowed general medical facilities in areas of a rapid COVID-19 outbreak to accept patients suspected of infection. Before this, patients could only get tested at specialized clinics after making an appointment with consultation centres to prevent the transmission of the disease. Government officials revised the previous policy after acknowledging that such specialized institutions would be overwhelmed during a large cluster.[328]

Third, the policy asked those with any cold symptoms to take time off from work and avoid leaving their homes. Government officials urged companies to let employees work from home and commute at off-peak hours. The Japanese government also made an official request to local governments and businesses to cancel large-scale events.[328]

On 27 February, Abe requested the closure of all schools from 2 March to the end of spring vacations, which usually conclude in early April. The next day, the Japanese government announced plans to create a fund to help companies subsidize workers who need to take days off to look after their children while schools are closed.[331]

On 27 February, the Japanese government also announced plans to expand the national health insurance system so that it covers COVID-19 tests.[332]

On 9 March, the Ministry of Health reconvened the Expert Meeting after the two week "critical moment." The panel of medical experts concluded that Japan was currently not on track to experience a large-scale cluster, but stated that there is a two-week time lag in analysing COVID-19 trends and that the country would continue to see more infections. Consequently, the participants asked the government to remain vigilant in quickly identifying and containing smaller clusters. With more COVID-19 outbreaks around the world, the panel also proposed that new infections from abroad could initiate a "second wave" of the disease in Japan.[333][334]

On 9 March, the Health Ministry published a disease forecast for each prefecture and instructed local governments to prepare their hospitals to accommodate its patient estimates. It predicts that the virus peak in each prefecture would occur three months after the first reported case of local transmission. The Ministry estimates that at the peak Tokyo would see 45,400 outpatients and 20,500 inpatients per day, of whom 700 will be in severe condition. For Hokkaido, the figure is 18,300 outpatients and 10,200 inpatients daily, of whom about 340 will be in severe condition.[335]

State of Emergency declaration[edit]

Broadcast message asking people to stay home in Tokyo

On 5 February, the Abe Administration's coronavirus task force initiated political debate on the introduction of emergency measures to combat the COVID-19 outbreak a day after the British cruise ship Diamond Princess was asked to quarantine. Initial debate focused on constitutional reform due to the task force's apprehension that the Japanese Constitution may restrict the government's ability to enact such compulsory measures as quarantines on the grounds that it violated human rights. After lawmakers representing almost all of the major political parties – including the Jimintō, Rikken-minshutō, and Kokumin-minshutō – voiced their strong opposition towards this proposal and asserted that the Constitution allowed for emergency measures, the Abe Administration moved forward with legislative reform instead.[336]

On 5 March, Abe introduced a draft amendment to the Special Measures Act to Counter New Types of Influenza of 2012 to extend the law's emergency measures for an influenza outbreak to include COVID-19. He met separately with the heads of five opposition parties on 4 March to promote a "united front" in passing the reforms. The National Diet passed the amendment on 13 March, making it effective for the next two years.[337][338] The amendment allows the Prime Minister to declare a "state of emergency" in specific areas where COVID-19 poses a grave threat to the lives and economic livelihood of residents. During such a period, governors of affected areas will receive the following powers: (1) to instruct residents to avoid unnecessary outings unless they are workers in such essential services as health care and public transportation; (2) to restrict the use or request the temporary closure of businesses and facilities, including schools, social welfare facilities, theatres, music venues and sports stadiums; (3) to expropriate private land and buildings for the purpose of erecting new hospitals; and (4) to requisition medical supplies and food from companies that refuse to sell them, punish those that hoard or do not comply, and force firms to help transport emergency goods.[339]

Under the law, the Japanese government does not have the authority to enforce citywide lockdowns. Apart from individual quarantine measures, officials cannot restrict the movement of people in order to contain the virus. Consequently, compliance with government requests to restrict movements is based on "asking for public cooperation to ‘protect people’s lives’ and minimize further damage to [the economy]".[340]

On 25 March, the Ministry of Health, Labour and Welfare announced that the daily number of confirmed cases in Tokyo increased from 17 to 41 cases compared to the day before.[95] Tokyo Governor Yuriko Koike held an emergency press conference in the late afternoon, stating that "the current situation is a serious situation where the number of infected people may explode." She requested residents to refrain from nonessential outings during the upcoming weekend.[96]

On 26 March, the Ministry of Health reconvened the Novel Coronavirus Expert Meeting to review the new data. The panel of medical experts concluded that there was a "high probability of an expansion of infections" within the country due to an increase in the number of infected patients returning from Europe and the United States between 11 March and 23 March.[4] In response to the statement, Abe instructed Economic Policy Minister Yasutoshi Nishimura to establish a special government task force to combat the spread of the virus.[341] The move cleared a prerequisite toward declaring a state of emergency because any request for one by the Prime Minister would have to be approved by such a task force under the revised law.[citation needed]

On 30 March, Koike requested residents to refrain from nonessential outings for the next two weeks due to a continued increase in infections in Tokyo.[342] During a press conference held by the Japan Medical Association that same day, Kamayachi Satoshi of the government's panel of medical experts stated that his fellow panelists were divided over whether Abe should declare a state of emergency.[343]

On 1 April, the Ministry of Health reconvened the Novel Coronavirus Expert Meeting to assess the current COVID-19 situation in Japan.[4] The medical experts discussed the data and concluded that although such urban areas as Tokyo and Osaka were witnessing a rapid increase in infection rates, they were not on a trajectory to experience a large-scale cluster seen in Europe and the United States. Experts were still concerned that infected patients could overwhelm the medical service system before an explosive spread of the virus as COVID-19 designated hospitals in major cities reached near capacity. They requested the government to secure more hospital beds for patients and transfer those with mild or no symptoms to outside housing facilities.[citation needed]

On 2 April, the Ministry of Health issued a notice that urged non-critical COVID-19 patients to move out of hospitals and stay at home or at facilities designated by local governments.[344] Prefectural governors across the country began arranging accommodation for such patients through hotel operators and dormitories and issued official requests to the Japan Self-Defense Force for transportation services.[345][346]

On 3 April, Professor Nishiura Hiroshi of the Ministry of Health's Cluster Response Team presented the initial findings of his COVID-19 epidemiological models to the public.[347] He concluded that the government could prevent an explosive spread of the virus in Japan if it adopted strict restrictions on outings that reduced social interactions by 80 percent, while such a spread would occur if the government adopted no measures or reduced social interactions by only 20 percent. Nishiura added that Tokyo was about 10 days to two weeks away from a large-scale outbreak.[348]

On 7 April, Abe proclaimed a one-month state of emergency from 8 April to 6 May for Tokyo and the prefectures of Kanagawa, Saitama, Chiba, Osaka, Hyogo and Fukuoka.[349] He stated that the number of patients would peak in two weeks if the number of person-to-person contacts was reduced by 70 to 80 percent, and urged the public to stay at home to achieve this goal.[350]

On 10 April, Koike announced closure requests for six categories of businesses in Tokyo.[351] They include amusement facilities, universities and cram schools, sports and recreation facilities, theatres, event and exhibition venues. and commercial facilities. She also asked restaurants to limit opening hours to between 5 a.m. and 8 p.m. and to stop serving alcohol at 7 p.m. The request was to take effect on 12 April and promised government subsidies for businesses that cooperated with it.

On 11 April, Professor Nishiura presented the remaining findings of his COVID-19 epidemiological models.[352][353] He determined that reducing social interactions by 80 percent would decrease the COVID-19 infection rate to a manageable level in 15 days; by 70 percent in 34 days; by 65 percent in 70 days; and by 50 percent in 3 months. Any rate below 60 percent would result in an increase in the number of cases.

On 16 April, Abe expanded the state of emergency declaration to include every prefecture within the country.[13]

Later on 4 May, Abe expressed that Japanese Cabinet would expand the state of emergency declaration until end of May.[154] Then on 14 May, Abe and his cabinet declared that Japanese Government decided to relieve the state of emergency declaration, excluding 8 prefectures like Tokyo, Kyoto Prefecture.[354] Some media expressed doubts about why only some of the easing standards were released under the name of comprehensive judgment.

On 21 May, the state of emergency is suspended in 3 prefectures in Kinki after they had cleared the threshold of having new infections below 0.5 per 100,000 people in the past week, resulting a total of 42 out of the 47 prefectures to be out of the state of emergency while 5 prefectures, such as Saitama, Kanagawa, Hokkaido, are waiting for lifting decision on May 25.[19][20]

Novel Coronavirus Expert Meeting[edit]

On 16 February, Abe convened the Novel Coronavirus Expert Meeting to incorporate members of the Japanese medical community into his decision-making process.[318] The panel acts as the main medical advisory body of the Japanese government during the COVID-19 crisis.[citation needed]


Vice Chair


Government support measures[edit]

On 12 February, Abe announced that the government would secure 500 billion yen for emergency lending and loan guarantees to small and medium enterprises affected by the COVID-19 outbreak.[355] He also declared that his Cabinet would set aside 15.3 billion yen from contingency funds to facilitate the donation of isolated virus samples to relevant research institutions across the globe.[356]

On 1 March, Abe evoked the Act on Emergency Measures for Stabilizing Living Conditions of the Public to regulate the sale and distribution of facial masks in Hokkaido. Under this policy, the Japanese government instructed manufactures to sell facial masks directly to the government, which would then deliver them to residents.[308] On 5 March, the Japanese government announced that it is organizing an emergency package by using a 270 billion yen ($2.5 billion) reserve fund for the current fiscal year through March to contain the virus and minimize its impact on the economy.[357]

Controversies and criticisms[edit]

On 17 February, the Ministry of Health, Labour and Welfare asked people who have had a fever over 37.5 °C for more than four days or those who have lethargy and difficulty breathing worse than those for influenza to consult with the coronavirus-related Return and Contact Consultation Centres around the country to determine if they should get tested for novel coronavirus.[358][359] However, some media outlets asserted that restrictive standards for testing would delay societal and public health responses, leading to the spread of the disease, which could later lead to the collapse of the health care system and the medically protected regional community.[15][360]

In early February, Masahiro Kami [ja], a hematologist, chairman of the Institute for Healthcare Governance, and outside director of SBI Pharma Co., Ltd. and SBI Biotech Co., Ltd., compared with Italy and criticized Japan's response to the cruise ship.[361] Japan quarantined everyone for two weeks, and then tested them all twice before releasing them but Italy disembarked all passengers in 12 hours. Italy only tested two people who were ill and suspected of being infected, and they tested negative, they immediately released all the remaining 6000 passengers.[362]

In late February, several Japanese media outlets reported that there were people with fever or other symptoms who could not be tested through the consultation centre system and had become "test refugees" (Japanese: 検査難民).[363][364][365][366] Some of these cases involved patients with severe pneumonia.[367] Hematologist Masahiro Kami claimed that many patients were denied testing due to their mild symptoms and criticized the Japanese government for setting testing standards that were too high and for lacking a response to patient anxiety.[368]

On 26 February, the Minister of Health Katsunobu Kato stated in the National Diet that 6,300 samples were tested between 18 and 24 February, averaging 900 samples per day. Some representatives questioned the discrepancy between the actual number of people tested and the claim in the prior week that 3,800 samples could be tested per day.[369]

On the same day, more doctors reported that public health centres had refused to test some patients. The Japan Medical Association announced that it would start a nationwide investigation and plan to cooperate with the government to improve the situation.[370] The Ministry of Health also stated that it would look into the situation with the local governments.[371]

The strict constraints on testing for the virus by Japanese health authorities drew accusations from critics such as Masahiro Kami that Abe wanted to "downplay the number of infections or patients because of the upcoming Olympics." It was reported that only a few public health facilities were authorized to test for the virus, after which the results could only be processed by five government-approved companies, which created a bottleneck forcing clinics to turn away even patients with high fevers. This has led some experts to question Japan's official case numbers. For example, Tobias Harris, of Teneo Intelligence in Washington, D.C., said: "You wonder, if they were testing nearly as much as South Korea is testing, what would the actual number be? How many cases are lurking and just aren't being caught?"[15][16] Fact-checking in several media later proved that the news that the government had reduced the number of tests to curb the increase in the number of infected people for the Olympics was fake news.[372][373]

Testing was still restricted to large hospitals in March 2020, with 52,000 tests, or 16% of the South Korean amount, performed that month. A decision to expand testing was made on 13 April 2020.[374] There were many articles in March that criticized the number of PCR tests in Japan as very small compared to South Korea.[375][376] However, the number of PCR tests in Japan at that time was actually not a few. According to data released by the Ministry of Health, Labor and Welfare, Japanese authorities conducted PCR tests of 10205 as of 13 March and 15655 as of 17 March, except for those returning from China by charter flights and passengers on the cruise ship. The number of tests in Japan seems to be very small compared to the countries with exorbitant tests such as China, South Korea and Italy, but it has never been smaller than the other countries.[377][378][379]

On March 5, Japan announced that it will strengthen quarantine for new entrants from China and South Korea and add some areas of Iran to the target area. The Chinese government showed their understanding of the decision, but the Korean government blamed Japan violently, saying that these were "unreasonable and excessive measures."[380][381][382][383][384]

There are various problems arising in connection with the Emergency Supplementary Income policies promoted by the Japanese government. At first, there were many obstacles to rapid driving force as the 300,000 yen per household policy was changed to the 100,000 yen per population policy. In addition, there are some uncomfortable parts that make it easier to evaluate postal delivery applications more faster than online applications. In the case of postal delivery, it is possible to apply for each household more smoothly, but when applying online, separate paperwork for inspection are required for each local government office. In addition, since the application process for management subsidies is complicated, there are also side effects of financial disadvantages for small business owners and individual business owners. The reason why the shortage of masks was difficult to eliminate and it took a long time to receive the benefits was that the Individual Number system, which was well known as My personal ID card Number System, was only used by about 16% of the population, meanwhile most of work could be handled without Individual Number system due to people's hesitation against privately problematic policy which gets into troublesome settlement for protection of private problem without supervision of government.[385][386] The Individual Number is a system for the administration to identify individuals. Due to opposition from the opposition party and liberals who say that the national and local governments will get to know personal information, the Individual Number has not spread easily and is not obligatory to link with other personal information such as bank accounts.[387][388] On this topic, Senetor Sanae Takaichi who leads Ministry of Internal Affairs and Communications commented that they are considering to connect every single personal ID card Number and each single bank account for comfort usage of every citizen.[389][390]

Moreover, Prime Minister Abe's cloth mask distribution policy is also problematic, so there is some lack of clarity in budgeting. Furthermore, one of the companies involved Mask supply production that are suspected ghost companies. Besides, the problem of maintaining quality, which was the trigger, remains under the government's burden, and the issue of tax waste is pointed out.[391][392] The company that was suspected to be a dummy company in some media was a broker of a sole proprietor, and he had masks manufactured in Vietnam using locally procured materials and imported them. Originally, he was promoting masks to Fukushima and Yamagata prefectures, but the Ministry of Health and Welfare, who had trouble finding a mask supplier due to a sudden decision, bought them.[391][392][393] Not only he, but also people and companies who were reported suspicious in the media or were rumored on social media were slandered online, and there were many nuisances to the company and their homes.[394][395][396]

Likewise, there were several news reports that showed signs for missing numbers of infection statistics in Japan could be explained by other sources of statistics.[397][398][399] Furthermore, there would be differences among several statistics of departments since there were several standards for statistics among regional directors and departments of Japanese Authorities using those statistics with other standards.[400] As a result, despite of low death rate, there were some doubt that there would be missing fatality cases for COVID-19 pandemic among Japan due to low credibility of statistics in Japan as well as some medical professionals and media outlets have criticized the Japanese government for under-testing for COVID-19.[citation needed]

Medical response[edit]

The medical task-force advising the government, known as the Novel Coronavirus Expert Meeting, has adopted a three-pronged strategy to contain and mitigate COVID-19 that includes (1) early detection of and early response to clusters through contact tracing; (2) early patient diagnosis and enhancement of intensive care and the securing of a medical service system for the severely ill; and (3) behaviour modification of citizens.[401] Medical experts have prioritized COVID-19 testing for the first two purposes, while relying on the behaviour modification of citizens rather than mass testing to prevent the spread of the virus at a large-scale level.[402]

Contact tracing against clusters[edit]

The Japanese government's COVID-19 countermeasures include public service announcements to avoid the "Three Cs".

On 25 February, the Ministry of Health, Labour and Welfare established the Cluster Response Team (Japanese: クラスター対策班) in accordance with the Basic Policies for Novel Coronavirus Disease Control.[403] The purpose of the section is to identify and contain small-scale clusters of COVID-19 infections before they grow into mega-clusters. It is led by university professors Oshitani Hitoshi and Nishiura Hiroshi and consists of a contact tracing team and a surveillance team from the National Institute of Infectious Diseases (NIID), a data analysis team from Hokkaido University, a risk management team from Tohoku University, and an administration team.[404] Whenever a local government determines the existence of a cluster from hospital reports, the Ministry of Health dispatches the section to the area to conduct an epidemiological survey and contact tracing in coordination with members of the local public health centre. After the teams determine the original source of infection, the ministry and local government officials enact countermeasures to locate, test, and place under medical surveillance anybody who may have come into contact with an infected person. They can also file requests to suspend infected businesses or restrict events from taking place there.[404]

From its contract tracing findings, the Ministry of Health discovered that 80% of infected people did not transmit COVID-19 to another person. The Ministry also determined that patients that did infect another person tended to spread it to multiple people and form infection clusters when they were in certain environments.[405] According to one of the experts, Kawaoka Yoshihiro, "[This meant that] you don’t need to trace every single person who’s been infected if you can trace the cluster. If you do nothing, the cluster will grow out of control. But as long as you identify a cluster small enough to contain, then the virus will die out."[406]

On 9 March, the medical experts reviewed the data from the Cluster Response Team's work and further refined its definition of a high-risk environment as a place with the overlapping "three Cs" (three crowdedness (Japanese: 三つの密, Hepburn: mittsunomitsu)): (1) closed spaces with poor ventilation; (2) crowded places with many people nearby; and (3) close-contact settings such as close-range conversations.[407] They identified gyms, live music clubs, exhibition conferences, social gatherings, and yakatabune as examples of such places. The experts also theorized that crowded trains did not form clusters because people riding public transportation in Japan usually do not engage in conversations.[407]

During times when the number of infected patients rises to such an extent that individual contract tracing alone cannot contain a COVID-19 outbreak, the government will request the broad closure of such high-risk businesses.[408]

Reinforcement of the medical system[edit]

During the initial stages of the outbreak, medical experts recommended the government to focus COVID-19 testing for contact tracing purposes and patients with the following symptoms: (1) cold symptoms and a fever of at least 37.5 °C (or need to take antipyretic medication) for over four days; and (2) extreme fatigue and breathing difficulties.[322] The elderly, people with pre-existing conditions, and pregnant women with cold symptoms could be tested if they had them for two days.[322][321] The country's high number of computed tomography (CT) scanners (111.49 per million people) allows them to confirm suspicious pneumonia cases and begin treatment before testing them for COVID-19.[citation needed]

On 1 April, medical experts requested the government to secure more hospital beds for patients and transfer those with mild or no symptoms to outside housing facilities to focus treatment on the severely-ill.[4]

Behaviour modification of citizens[edit]

The Japanese government's medical task-force anticipates multiple waves of COVID-19 to arrive in the country for at least the next three years, with each one prompting the public to engage in a cycle of restricting and easing movement.[406] Under the current law, the Prime Minister can restrict movement by declaring a "state of emergency" in specific areas where COVID-19 poses a grave threat to residents. During such periods, the governors of affected areas can request citizens to avoid unnecessary outings and temporarily close certain businesses and facilities. Since the government cannot enact compulsory measures to enforce these requests, it has instead embarked on a social engineering program to train its citizens to comply with them on a voluntary basis during current and future state of emergencies.[406]

To reduce person-to-person contact, the government has instructed the public to refrain from going to high-risk environments (the Three Cs: closed spaces, crowded places, and close-contact settings) and events involving movement between different areas of the country.[408] It emphasized extreme caution when coming in contact with the elderly. The government also promoted such work-style reforms as teleworking and staggering commuting hours, while improving the country's distance learning infrastructure for children.[408]

On 4 May, the Ministry of Health, Labour and Welfare unveiled its program to create a "new lifestyle" (Japanese: 新しい生活様式) for the country's citizenry that is to be practiced everyday on a long-term basis.[409] Several elements of the lifestyle include behavior changes demanded under the state of emergency, such as avoiding high-risk environments and long-distance travelling. However, the program expands these precautions to cover more mundane activities by requesting people to engage in such activities as wearing masks during all conversations, refraining from talking when using public transportation, and eating next to one another rather than facing one another.[408][409]

Regional developments[edit]

The following are examples of the spread of infections for three of the eight regions in Japan.


The first case was identified in Hokkaido on 28 January 2020,[410][411] and the first case of an infected person in Hokkaido was on 14 February.[410][412] To limit the spread of infection, the governor of Hokkaido, Naomichi Suzuki, announced the Declaration of a New Coronavirus Emergency on 28 February, calling on locals to refrain from going out.[413]


On 13 February 2020, three confirmed cases were announced in the Kanto region, and one case was confirmed in each of Kanagawa, Tokyo, and Chiba. On 6 March 2020, it was confirmed that 121 infected people were reported in 5 prefectures, including Tochigi and Saitama. On 21 March, a total of 136 people were identified as infected in Tokyo, and a total of 311 people were confirmed in the Kanto region.[citation needed]


The first case was identified in Aichi on 26 January 2020,[414] and the first case of an infected person in Aichi was on 14 February.[414] As the virus spread, Governor Omura of recognized that there were two clusters in the prefecture, mainly in Nagoya.[415] He emphasised the need to work with the Nagoya City Government to prevent the spread of infection.[415]

Socio-economic impact[edit]

Abe said that "the new coronavirus is having a major impact on tourism, the economy and our society as a whole".[416][417] Japan into recession. In Q1 2020 GDP there was 0.9 contraction, whereas in Q4 2019 GDP there was 1.9 contraction.[418] Face masks have sold out across the nation and new stocks are quickly depleted.[419] There has been pressure placed on the healthcare system as demands for medical checkups increase.[420] Chinese people have reported increasing discrimination.[421]

The aviation, retail and tourism sectors have reported decreased sales and some manufacturers have complained about disruption to Chinese factories, logistics and supply chains.[422] Abe has considered using emergency funds to mitigate the outbreak's impact on tourism, 40% of which is by Chinese nationals.[423] S&P Global noted that the worst hit stocks were for travel, cosmetics and retail companies, which are most exposed to Chinese tourism.[424] Nintendo warned that delays on shipments of hardware and accessories for its Nintendo Switch video game console would be "unavoidable" due to the impact on its Chinese supply chain and manufacturing, and on 7 April announced that shipments to Japan would be delayed due to increased demand for the device.[425][426]

On the same day the Nagoya Expressway Public Corporation announced plans to temporarily close some toll gates and let employees work from their homes after an employee staffing the toll gates was diagnosed positive for SARS-CoV-2.[427] Due to personnel shortages, six toll gates on the Tōkai and Manba routes of the expressway network were closed over the weekend.[427]

Sporting events[edit]

The outbreak has affected professional sports in Japan. Nippon Professional Baseball's preseason games and the Haru Basho sumo tournament in Osaka were announced to be held behind closed doors, while the J.League football and Top League rugby suspended or postponed play entirely.[428] On the weekend of 29 February, the Japan Racing Association closed its horse racing meets to spectators and off-track betting until further notice, but continued to offer wagering by phone and online.[429]

The outbreak expansion has affected sports schedule of school in Japan. Since these outbreaks led to concerns over the health risk of the students, sporting event, such as baseball, basketball, soccer, in school were suspended or postponed play entirely, due to unexpected postpone of education schedule by nationwide outbreaks, as well as other sports events decided to delay its season.[citation needed]

The expansion of COVID-19 into a global pandemic led to concerns over the 2020 Summer Olympics and Paralympics in Tokyo. In March, it was announced that the Games would be postponed by a year, for the first time in the history of the modern Olympics.[430][431]

Two Yomiuri Giants players have tested positive for the new coronavirus, the Central League team announced on June 3, casting a shadow over Nippon Professional Baseball's plan to start the 2020 season on June 19.[194]


On 26 February, Abe suggested that major sporting, cultural and other events should be cancelled, delayed or scaled down for about two weeks amid the new coronavirus outbreak.[432] As a result, J-pop groups Perfume and Exile cancelled their concerts scheduled that night at Tokyo Dome and Kyocera Dome Osaka, respectively, both of which have a capacity of 55,000.[433] On 27 February, AnimeJapan 2020, originally scheduled to be held in Tokyo Big Sight in late March, was cancelled.[434]

A number of major amusement parks announced temporary closures. On 28 February, Tokyo Disneyland, Tokyo DisneySea and Tokyo Disney Resort were temporarily closed from 29 February.[435][436] Universal Studios Japan also announced a closure the same day.[437] By mid-March, some attractions began to partially reopen, with Huis Ten Bosch and Legoland Japan Resort reopening with limited services (outdoor attractions only, visitors subject to temperature checks before entering) on 23 March.[438][439] However, the Disney parks and Universal Studios Japan delayed their re-openings until mid-to-late April.[437][440][441] Later on July 1st, Tokyo DisneySea and Tokyo Disneyland reopened after they reported their plan on 25 June.[442]

Affected by the shortage of outsourced staff due to the COVID-19 outbreak, many Japanese animated films and TV shows announced changes or postponed broadcasts due to production problems, including A Certain Scientific Railgun T (deferred for broadcast, changed to rebroadcast), Asteroid in Love, A3! (Delay extension), Kukuriraige -Sanxingdui Fantasy- (Delay extension), etc.[443][444] On 31 March, TV Asahi announced that Rio Komiya, who plays Jūru Atsuta in the tokusatsu series Mashin Sentai Kiramager, had tested positive for COVID-19.[445][446] While production had been suspended, it was stated that there were enough completed episodes to last through 10 May.[447][448]

On 25 March, it was announced that Japanese comedian Ken Shimura had tested positive for COVID-19.[449][110] Shimura died on 29 March at the age of 70.[450][451]

Not only anime series but also drama series have been silently refrained production to prevent the spread of infection, and most of telecasting stations are transmitting works from past years. In Nippon TV, the airing schedule of "The pride of the Temp", starring Ryoko Shinohara and Yo Oizumi, has been postponed, as well as the airing schedule of "Minwan Police", starring Kento Nakajima and Sho Hirano, has been postponed.[452] In TBS Television, the airing schedule of "MIU404", starring Gen Hoshino and Gou Ayano, has been postponed, as well as the airing schedule for "Hanzawa Naoki 2", starring Masato Sakai and Mitsuhiro Oikawa, has been postponed.[453] In Fuji TV, The schedule for airing the manga-based medical drama series in the second quarter, starring Satomi Ishihara and Nanase Nishino, has been postponed,[454] as well as the airing schedule for "Suit Season 2", starring Yuto Nakajima and Yuko Araki, has been suspended.[455] Meanwhile, NHK announced that the schedule for three drama series would be postponed under the influence of the new coronavirus.[456] "The broadcast date will be announced on the program guide and website as soon as it is decided," said the station.[457]

On April 19, 2020, TV Tokyo, MediaNet & ShoPro announced that the Pokémon anime series will be going on hiatus, with production temporarily suspended.

Distance learning[edit]

On 27 February 2020, Prime Minister Shinzo Abe requested that all Japanese elementary, junior high, and high schools close until early April to help contain the virus.[5][461] This decision came days after the education board of Hokkaido called for the temporary closure of its 1,600 public and private schools.[462] Nursery schools were excluded from the nationwide closure request.[5] As of 5 March, 98.8 per cent of all municipally run elementary schools have complied with Abe's request, resulting in 18,923 school closures.[463]

Along with the school suspension, the online education was being piloted in some areas where the health crisis was not severe, but there was a concern that the education gap was widening in each region due to the limited online environment in Japan. Due to the sudden public health crisis, school closures are taking place in the middle of school, and education gaps in each region and childcare problems in the home have led to difficulties in education. While there are promising plans to postpone the start of the new semester to September, centered on local politics, there are also opinions that some require careful approach to changing the semester system. Those who promotes semester change into September are pursuing a new semester change on the basis of bridging regional gaps and meeting world standards, and those who ponders semester change argue that the online education environment needs to be rapidly updated by region before the semester change.[464][465]


Due to prejudice and ignorance, social harassment is expanding in relation to infectious diseases. Because of their worries about being contracted, the number of cases where medical personnel's family commuting is restricted or people around the infected person are disturbed has increased. In addition, there are increasing cases where small business owners, who were inevitably operating, are forced to take self-sufficiency by neighbours who feel anxious and deprived.

While telecommuting is being encouraged, videoconferencing is also increasing the number of psychological pressures caused by authoritarian attitudes and sexual harassment. The negative effects of telecommuting also exacerbated the problem of privacy infringement, leading to exposure of privacy in the workplace and social pressure. Some companies have compulsory video conference participation rules, with public request of active reactions and optimistic expressions.

As the number of telecommuting cases increased, the number of working hours in the homes of workers increased, causing conflicts between women and men. In some cases, the number of cases of domestic violence has also increased by increasing discord among families.

Aid to China[edit]

On 26 January, Japanese people donated a batch of face masks to Wuhan.[466] According to the Liberty Times of Taiwan, these were actually purchased by China,[467] but Japanese media and the Japanese Consulate General in Chongqing [ja] stated that it was a donation.[468][469]

On 3 February, four organizations, the Japan Pharmaceutical NPO Corporation, the Japan Hubei Federation, Huobi Global, and Incuba Alpha, donated materials to Hubei.[470]

On 10 February, the Liberal Democratic Party's Secretary General Toshihiro Nikai said that the party would deduct 5,000 yen from the March funds from members of the party to provide mainland China with support.[471]
