Climate
There are a lot of climatic differences between the southern islands (Kyushu, Shikoku) and Hokkaido in the north. In southern Japan, a subtropical climate leads to a wet season happening between June and July. The summer is humid in the whole country with tropical storms and typhoons (sharp winds, torrential rain) occurring between August and October.
The temperatures are a bit cooler in Hokkaido, where winter is very cold and snowy in the north, as well as on the west coast of Honshu, due to the icy Siberian winds sweeping through the Sea of Japan. The east coasts and Kyushu benefit from a warm climate and bright sunny days during that season. Fall and spring are the best times to travel to Japan, as both are enjoyable with mild temperatures and rare rainfall.
