Japan climate guide

Japan weather overview

Japan, a group of mountainous volcanic islands off the coast of Asia, has a predominantly temperate, seasonal climate with cool to cold but sunny winters, warm to hot summers and mild weather in the spring and autumn. However, there are exceptions to this: the island of Hokkaido and the northern areas of Honshu experience heavy snows in the winter months when cold winds gust in from Siberia, gathering moisture from the sea as they come. In central and southern Japan, winter is the (relatively) dry season while there is moderate rainfall in the summer and autumn with the chance of a typhoon, accompanied by heavy rainfall, blowing in from the South China Sea from July to September. Southern summers tend to be warm and humid with heavy cloud cover. The mountain areas are usually the most pleasant parts of Japan in the summer months when conditions are predominantly sunny and crisp. Spring is the best time to visit the lower parts of the country; it brings not only fresh, sunny weather but also the legendary 'cherry blossom time'.

What to pack for Japan weather

While light clothes are fine in the summer, you should combine light clothing with some warmer attire in the spring and autumn, and take much warmer clothing for the winter and visits to the mountain areas. Go prepared for rain in the summer.
