Oigami Onsen Kinryuen

A well-kept small inn in Oigami Onsen, with a rocky open-air bath (rotenburo, 露天風呂) fed by a free-flowing source and a separate private open-air bath available to reserve. The entire building is floored with tatami, no slippers, which gives it an old-fashioned, grounded feel. Rooms and baths are consistently praised for their cleanliness despite the building's age.
