Japanese climate

The Japanese live in a temperate country; the North tends to be cool and subtropical in the South. The seasons in Japan are very distinct thanks to its location near the Asian continent and the proximity of two major ocean currents. The Kuroshio Current provides warm air and water whilst the Oyahio current is cold.

The seasons

The Japanese are proud of their four seasons with some believing that it is only in Japan that the seasons change.


This season often begins with a dreary wet season in June and turns into a sauna in July and August. Typhoons can occur in this season with vicious tropical storms battering the coasts. Unpleasantly Japans summers come with very high humidity, creating a hot sticky and downright unpleasant environment in the cities and urban areas. Temperatures can get as high as 35°C in 2004 Tokyo reported a record high of 39.5°C and a heat wave that lasted for 41 days in a row.


Japans autumn season begins in September and is a far more pleasant environment to live in then the summer months. Temperatures become far more pleasant and the autumnal colours of the trees are often spectacular.


Remarkably for such an advanced country, very few Japanese homes are fitted with central heating. Winters can be incredibly cold in the North of the country with snow falling in many regions. To avoid the cold you should head to Okinawa and to warmer climes.  The winters are often accompanied by strong winds. High pressure systems form over Siberia bringing in bitterly cold dry air.


Spring is by far the best time to be in Japan. The temperatures are warm but not hot, there’s not much rain and March-April brings the world famous natural wonder of the blooming of the cherry blossoms. It is also a time of festivities and parties with the Golden week occurring from April 27th to May 6th.
