Weather of Japan
In the winter months (December to February), cold, dry air-masses
from Siberia move down over Japan, where they meet warmer, moister
air-masses from the Pacific. The resulting precipitation causes huge
snowfalls on the side of the country that faces the Sea of Japan.
The Pacific Ocean side of Japan receives less snow but can still be
quite cold, while the big cities of Honshū like Tokyo, Osaka, Nagoya
and Kyoto have winters with highs in the single digits or even low teens
and lows a few degrees above zero (Celsius). The odd January or
February day will be colder, but these cold snaps usually don’t last.
The summer months (June to August) are dominated by warm, moist
air currents from the Pacific, and produce high temperatures and
humidity throughout most of Japan (with the blissful exception of
Hokkaidō). In the early part of summer, usually mid-May to June, there
is a rainy season lasting a few weeks that starts in the south and
gradually works its way northward.
Although it can be inconvenient, this rainy season is not usually a
significant barrier to travel. August, September and October is typhoon
season, which can make travel in Okinawa, the Izu-shotō and
Ogasawara-shotō difficult.
In contrast to the extremes of summer and winter, spring (March to
May) and autumn (September to November) in Japan are
comparatively mild. Rainfall is relatively low and the days are often
clear.
