By Albee NingUpdated Nov. 11, 2022

Japan is quite hot and humid in September, especially the south and central parts, with average temperatures ranging 16–30ºC (60–85°F). There are occasional typhoons on the east coast, with strong winds and precipitation of around 160 mm (6 in).

As September marks the start of fall, it gets cooler and drier by the end of the month, and peak season travelers start to disappear. September is a good time to travel; there are good prices on offer and fewer crowds.

Why You Should Visit Japan in September

September is a great time to enjoy two distinct seasons — summer and fall. You can enjoy the hot weather on the southern beaches, but also experience the fall colors and cooler weather of Northern Hokkaido.
