Bathing Arrangements
Private bath available for day-use visitors or hotel guests to reserve
The single shared bath (men's/women's) is let out in 1-hour private slots per staying group, 15:15-22:30 and 6:15-9:00; free (non-reserved) access the next morning.
Private onsen bath in guest rooms, for overnight guests only
Guest room amenity list (和室, bedding, bath towel, onsen towel, yukata, kotatsu, wifi, shared/共同 toilet) lists no in-room onsen bath; the inn uses a single shared bath booked by the hour instead.
Shared bathing area for all genders
Bath is split into separate men's/women's rooms let out on a schedule, not mixed bathing.
Policies & Services
Welcomes children and families
One reviewer describes visiting with a child who enjoyed the manga collection; the site's own copy leans adult/couples-oriented in tone but states no explicit child restriction.
Restaurant or dining open to visitors (not just hotel meal plans)
FAQ confirms the bar/dining counter can be used by non-staying visitors with a phone reservation (question: バーのみのご利用もできますか？). It is a bar-style dinner/breakfast counter, not a conventional 食事処.

About
The inn's single bath, split into men's and women's sides, is booked in hour-long private slots, one group at a time, and includes both an indoor tub and an open-air one. The water is milky white with a faint sulfur smell, from a spring on the mid-slope of Mt Norikura that's been piped down to the plateau since 1976. What sets the inn apart is the bar built into it: the owner spent years behind the counter at a hotel in Tokyo before opening this place, and now mixes cocktails and pours sake for guests still warm from the bath. Rooms are simple tatami, and there's a stack of manga to read between soaks.
