What is the climate like in Japan?

Japan has four distinct seasons. Summer can be very hot and muggy, reaching as high as 90% humidity. A rainy season (tsuyu) usually occurs from June to mid-July, with a stretch of monsoon lasting perhaps a week. Fall (September to November) and spring are more moderate. In winter, the temperature often drops below freezing in early morning and nighttime. If it does snow in Tokyo, it usually won’t last long.

Most Japanese homes do not have central heating, so temperatures in the home can be very low. They tend to control temperature in each room separately. If your room has heating or other equipment, please learn how to use it properly when you arrive, and remember to turn it off when you leave the room.
