  • Japan’s climate is rainy and humid, and marked in most places by four distinct seasons.


  • The country has pronounced differences in climate between the north and the south.
    • Northern Japan experiences long, harsh winters and relatively cool summers.
    • Central Japan has cold but short winters and hot, humid summers.


  • In Tokyo, in central Honshū, temperatures average 3°C (38°F) in January and 25°C (77°F) in July. Average temperatures in the southern city of Kagoshima are 7°C (45°F) in January and 26°C (79°F) in July. Farther south, the Ryukyu Islands are warmer still, with frost-free winters.


  • From June to September, monsoon winds from the Pacific bring warm, moist air and heavy precipitation to Japan’s Pacific coast.


  • A month-long rainy season called baiu begins in southern Japan in early June. Baiu is followed by hot, humid weather.


  • In late August and September, the shūrin rains come to much of the country—often as torrential downpours that trigger landslides and floods. During this period, violent storms called typhoons may come ashore in Japan.


  • Autumn and spring are generally pleasant in all parts of Japan. The season when cherry blossoms open (photo) (typically late March to early May, depending on latitude and elevation) is particularly festive.
