Hachimantai Onsenkan Mori no Yu, in Hachimantai, Iwate Prefecture, heats sulfurous water to 44°C. The bathhouse offers an indoor bath, rotenburo and sauna.

Insider tip — Mori no Yu, the forest spring, draws from the volcanic Hachimantai highland where the borders of Akita and Iwate meet in a plateau of geothermal craters, alpine wetlands, and snow-dusted beech forest. The sulfurous spring water has the milky blue-white appearance typical of active volcanic discharge in this extraordinary landscape.
