resort town
Two interconnected Hakuba faces — 47's terrain park and Goryu's wide groomers under one lift ticket, plus the valley's best night-skiing.

powder-focused
The snowiest resort in Hakuba Valley and Japan's finest steep in-bounds tree skiing — the Hotel Green Plaza at the base makes it the most underrated ski-in option in the country.

family-focused
Japan's widest beginner piste, plus the Tsugaike DBD — lift-served backcountry zone on the top of the mountain. Rare resort that works for a first-timer AND a freerider.
