Opened 300 years ago, Sukayu Onsen is a hot spring inn that serves guests seeking the therapeutic benefits of the hot spring. It sits on a cool highland approximately 900 m above sea level at the western foot of Mt. Odake, the main peak of the Hakkoda Mountains. The bathhouse, constructed entirely of Japanese cypress, has a rustic, traditional charm and its enormous "1000-person Japanese cypress bath" (hiba sennin furo) is well-known throughout Japan. The bathing area, 160 tatami mats in area (245 m²), features baths drawn from four different source springs. Included are a hot bath, a cool bath, a "40/60 split" bath, and a waterfall bath. In 1954, Sukayu Onsen was designated Japan's first National Health Spa in recognition of the hot spring's outstanding therapeutic effects and the local climate's suitability as a health resort.
