Since 2016, shortly after debuting, Twice began doing modeling endorsements with Pocari Sweat, a Japanese bottled water company. It was one of their first appearances specifically in Japanese media, and immediately became a huge hit in Japan.
In 2017, the group began to make Commercial Films (CF) for Pocari. Since then, Twice has continued endorsements, and are the longest-running models for Pocari.
In 2020, Pocari Sweat ended their 3 year endorsement with Twice.
