Sujiyu Onsen Sanso Yamano Sai

A small mountain inn in the Kuju highlands, and a reliable base for hiking the surrounding peaks. Most rooms have their own private open-air bath (rotenburo, 露天風呂) fed by free-flowing source water, so you can soak at any hour. Dinner is served around an irori (囲炉裏, open hearth), and the water itself is soft with no strong smell.
