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: spring, summer, autumn and winter. The most beautiful seasons are spring and autumn, because of the cherry blossoms (Sakura) and the beautiful colors of the autumn leaves.

Spring months are March, April, and May. Autumn months are September, October, and November. From late May to late June, or sometimes early July, Japan has a months-long 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 in early autumn.

Winter lasts on average from December to March. The more north you are the greater the differences in season. The far north and south of Japan have very different climates. In March you can for example sunbath in the south, but ski in the north.

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.
