Climate and Average Weather in Japan
The climate in Japan varies widely from one region to another region. The largest part of Japan has a temperate maritime climate and most of the country has four distinct seasons. The most attractive seasons are spring and autumn, because of the cherry blossoms (Sakura) and the beautiful colors of autumn leaves.
Spring is from March til May and autumn is from September til November. From late May to late June, or sometimes early July, Japan has a rainy season (Tsuyu). The air becomes moist and wet and the humidity can become so high that you can not dry clothes outside. Another period of regular rainfall is early autumn.
In the south of Japan, where the weather is more Mediterranean and subtropical, you only have two seasons. Winters are mild with a fair amount of precipitation, summers are warm to fairly hot with large amounts of rain.
