Uses natural hot spring water
Open-air outdoor bath
Enclosed indoor bathing area
Private onsen bath in guest rooms, for overnight guests only
Nihon Hitou wo Mamoru Kai booking listing shows 0 of 7 guest rooms have their own bath/rotenburo (rooms are plain washitsu with toilet only, no bath).
Shared bathing area for all genders
Restaurant or dining open to visitors (not just hotel meal plans)
Day-use lunch (日帰り昼食) can be added to a day-bathing visit, including the inn's 白山百膳 course meal, by reservation; a 150-yen bathing tax applies when lunch is included. A prior research pass characterized dining as stay-guest-only (in-room kaiseki); this listing's own day-use-lunch line, plus its explicit note about the added bathing tax for lunch, indicates day visitors can in fact book a meal, so this is kept as YES with the reservation condition noted.
Shower, wash stations, soap and shampoo provided
Towels available to rent or borrow
Hand towel and bath towel both marked as provided in the facility's amenity table on the booking listing.
On-site or nearby parking available
The indoor bath is on the ground floor; the open-air bath is four floors up, looking out over forested mountain ridges. Both run on kakenagashi (源泉掛け流し), unrecirculated spring water, and the spring can be drunk directly at the source. It is a small, rustic place with old wooden fittings and an unhurried atmosphere, and a member of Nihon Hitou wo Mamoru Kai (日本秘湯を守る会), the society that looks after Japan's lesser-known hot springs. The inn is open from late spring through late autumn only.
