なだらかな斜面が多いと言われる日本ですが、急斜面も確実に存在します。ターゲットにすべき山を教えます。

The "Mellow" Reputation If you are used to the 45-degree chutes of Revelstoke or Chamonix, your first day in Niseko might feel a bit flat. Japan is a land of massive accumulation, but relatively low-angle terrain. The Reality: If you want steep, technical skiing, you have to go to the mountains that have a bit of "teeth." At JapanSnowWatch, we’ve hunted down the vertical. --- 1. Hakuba Valley (Happo-One & Cortina) This is the steepest valley in Japan. Happo-One: The "Skyline" and "Kokusai" areas have some serious pitch, especially on the ungroomed days. Cortina: The bowl at Cortina is the steepest "lift-access" terrain in Honshu. It’s essentially a giant funnel that catches all the snow.

Warning: It gets tracked out by 10 AM. 2. Lotte Arai (The Freeride Mecca) Lotte Arai was rebuilt specifically to cater to freeriders. The Terrain: They have massive avalanche-controlled "Avalanche Zones." These are basically off-piste zones with serious pitch and huge vertical. Why go? It gets some of the highest snowfall in the world and has some of the longest continuous steep runs. 3. Tenjindaira (The Secret) Located in Gunma, this is a "skier's mountain." The Vibe: Tiny resort, massive backcountry.

The Terrain: The "gates" here lead to some of the most dangerous and technical terrain in Japan. It’s a place for experts with full avi-gear and knowledge. --- Don't forget the humidity. "Steep" in Japan often means high avalanche risk. Our snow is heavy and builds up fast. If you go into the steeps, you must have a beacon, probe, shovel, and the knowledge to use them.
