The five add up to the 100-point Powder Score: more fresh snow, more on the way and colder air all push it up. How we measure
The Dynamic Course is certified by the Ski Association of Japan. From the slopes, the snow-covered Shokanbetsu-dake and the Sea of Japan are both in view. The lodge is a two-storey, Nordic-style timber building whose canteen serves light meals such as noodles, curry and steamed buns.
