Need some basic help in planning a 12 night family vacation to Japan in early August. We are two adults in 60s and two young adult sons. We are flying from LAX to Tokyo and would like to return home from Kagoshima. Need some basic advice with these preferences:

1. Not too many days in Tokyo, just the basic sites as we don’t love big modern cities and prefer more historic sites, etc. Thinking 3 nights? Ideas for hotels close to public transport helpful

2. Want to see Kyoto, day trip to Naga

3. Osaka optional

4. Would like to see Niroshima

5. End up in Kagoshima, as my stepdad lived there for years and it sounds like somewhere we would like.

6. No driving

7. Mt Fuji not a priority

8. Often use day tour companies like Viator to take city tours.

We like outdoors, nature sites, some temples, maybe a neat shopping area at least once for sons.

Can anyone please give some input? We’d like to see the main sites, it also understand that our trip is pretty short and lots will go unseen. Thanks I. Advance
