Hachimori Onsen, also known as Yurinko, is located in Yuza, Akita Prefecture. Its sodium-chloride water emerges at 41°C (pH 7.3), feeding an indoor bath and an outdoor rotenburo, alongside a sauna.
Insider tip — Hachimori Onsen Yurinko is a community hot-spring facility on the Akita coast near the village of Yuza, surrounded by rice paddies and the distant outline of Chokai Volcano. The sodium-chloride water at 41°C is warm and nourishing, especially valued during the long Tohoku winters when locals treat regular bathing as essential to staying healthy. The unassuming building belies the quality of the source, and the modest entrance fee makes it accessible to everyone in the community. A rotenburo at the rear offers an open-air soak with views toward the Japan Sea on clear days.
