Skiing in Japan — Snow Data for 6 Ski Resorts
Japan is the powder capital of the world. Cold Siberian air masses cross the Sea of Japan, picking up moisture before dumping extraordinary quantities of ultra-light, dry snow on the mountains. Hokkaido averages over 14 metres of snowfall annually.

Ski Resorts in Japan by Snowfall
Best Time to Ski in Japan

The Skiing Experience in Japan
Steep tree skiing through silver birch forests, open bowls, and legendary off-piste zones. Japan's resorts are purpose-built for powder hunting.
Japanese ski culture blends world-class powder with onsen (hot spring) bathing, exceptional cuisine (ramen, sushi, sake), bullet-train access, and meticulous hospitality.
"Japow" — the ski community's term for Japan's legendary powder — is produced by the Sea of Japan effect: cold Siberian air masses absorb moisture crossing the Sea of Japan, then deposit enormous quantities of ultra-light snow on the mountains of Honshu and Hokkaido. Japan receives more annual snowfall than almost any other country on earth.
