Funasawa Onsen welcomes visitors in Noshiro, on the coast of Akita prefecture. Sodium-chloride water rises here at 42°C, feeding an indoor bath, an outdoor rotenburo and a sauna.
Insider tip — Noshiro has shaped Japanese architecture for centuries as the source of the finest sugi cedar lumber, used in temples, shrines, and traditional houses nationwide. Funasawa Onsen draws from the saline coastal aquifer of the Yoneshiro River delta, and the surrounding forests of cedar and beech are particularly majestic.
