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.
