بارش برف سنگین در ژاپن
During winter, cold air masses from Siberia blow towards Japan, picking up moisture from the Sea of Japan in the process. The wet cold air collides with the mountains along the Sea of Japan coast, resulting in heavy snowfall. Some areas experience extreme amounts of precipitation with snow depths of three to six meters.
Fittingly, Japan offers many popular destinations for snow seekers. While most of Japan's major cities, including Tokyo, Kyoto and Osaka, receive only small amounts of snow, locations offering snow experiences are readily accessible from them. The snow season in Japan is long and in some places begins as early as November and lasts into May, with the peak being in February.
