Onsen Ryokan Tennoyu is a hot spring inn in the town of Mori, in southern Hokkaido. Its sodium-chloride thermal water is kept around 40°C (pH 7.3), with an indoor bath, an outdoor rotenburo and a sauna.
Insider tip — Onsen Ryokan Tennoyu in Mori-machi faces Funka-wan (Volcano Bay) — named for the eruptions of Usu Volcano that shaped this circular bay over thousands of years. Mt. Komagatake's symmetrical cone is mirrored in the bay on still mornings, creating one of Hokkaido's most iconic volcanic reflections. The ryokan's hot spring baths offer volcanic coastal views across the bay toward the Oshima Peninsula's forested shores. The famous Mori corn, sold hot from station vendors, is the perfect accompaniment before checking in.
