Summer in Japan runs from June to August. The weather gets increasingly hot and humid, with the rainy season starting mid to late June. It does not rain every day however, nor all day long. Hokkaido and mountain areas are cooler than other areas. The typhoon season starts late August and affects southern Japan the most.

Peak travel time
While current measures against coronavirus restrict travel, it is too early to know whether they will continue into the summer which usually does have some peak travel times. Japan’s school holidays start late July and continue through August. Obon week in mid-August is a major holiday time for Japanese people with many companies giving their staff time off.
Summer flowers bloom all over Japan – lavender fields in Hokkaido, hydrangeas in Kamakura, and irises in gardens everywhere. Summer is also a popular time for festivals and fireworks, but some of these have already been cancelled, including the major Sumida fireworks festival in Tokyo.
The climbing season for Mt Fuji opens in early July and runs to early September.
Many tourist attractions are closing or curtailing their services. Be sure to check and confirm before going to visit. A list of closed tourist attractions and cancelled events can be found on the JNTO website and in Time Out.
