Uses natural hot spring water
Open-air outdoor bath
Enclosed indoor bathing area
Asahiya Ryokan is a plain, older inn in Nakanosawa Onsen (中ノ沢温泉) with an indoor bath and an open-air bath (rotenburo). The spring water is piped in from about 7 km away. A reviewer describes it as faintly sulfur-scented and cloudy with plenty of floating bath flakes (yu-no-hana, 湯の花). The rooms are simple Japanese-style ones, and the building is showing its age: reviewers mention worn tiles in the baths, dim corridors and thin staffing, so it suits people who come for the water rather than the service.
