Otobe Onsen (Ikoi no Yu) is located in Otobe, on the Oshima Peninsula, Hokkaido. The sodium-chloride water reaches 42°C, pH 7.3. It offers an indoor bath, an outdoor rotenburo bath and a sauna.
Insider tip — Ikoi no Yu, the rest and relaxation spring, serves Otobe-cho on the quiet Sea of Japan coast of southern Hokkaido where the mountains descend directly to rocky shores. The community has maintained this small fishing and farming lifestyle for generations, and the spring is the social centrepiece of the village through the long Hokkaido winter.
