Bathing Arrangements
A private bath you can reserve for yourself or your group
Multiple independent Google reviews (2022–2024) describe the bath(s) as private/reservable via an occupancy sign, used one party at a time, including as a family bath (家族風呂) — not stated in these exact terms on the official site.
Shared bathing area for all genders
Reviews describe a sign-based, one-party-at-a-time occupancy system for both tubs (used as family baths), which precludes mixed bathing.

About
The bath is a milky white, silky sulfur spring pumped straight from the source, unheated and undiluted. It fills two small indoor tubs in the guesthouse's older wooden wing, and works on a private, turn-based system: a sign on the door shows when a tub is free, so most guests end up with it to themselves. Rooms range from plain tatami singles to a twin-bed western room, gathered around a shared lounge with free drinks where guests tend to chat. It's a common stopover for people climbing Mount Norikura, and stays are self-catering, with no meals served on site.
