Autumn is from September to November and is characterised by light breezes and cooler temperatures of around 46-50ÂºF. Itâs during autumn that many exhibitions, music concerts and sports tournaments are held in Japan.
I've been to Japan in August and the heat and humidity were awful. September is a little bit better, and by mid-October, it is comfortable. So I would suggest visiting in October if you can. However, be aware that there is a tradeoff between humidity (which peaks in the summer) and typhoons (which occur in the fall).
