Evenings can be cool but when the rain stops it gets hot and extremely humid, so pack accordingly. From the end of August to the September is typhoon season. Although most storms run their course before they hit the mainland, you can count on one or two a year, which can wreak havoc on travel plans. Autumn Fall in Japan lasts until November, and it is arguably the best time to travel.

Days are cool and clear, and the radiant fall colors can be seen everywhere.
