About
A small inn in Iwamuro Onsen with five guest rooms, dating back to the Edo period. The water is natural onsen water. There is a men's bath and a women's bath, plus a private open-air bath (rotenburo, 露天風呂) that can be booked for your own party. Kaiseki meals are served at the inn, and the feel is quiet and unfussy, with plain rooms and warm wood throughout.
