Guide
What visitors add
The water
The water is notably hot — at least seven reviewers describe it as hot to scaldingly hot (one: 'more painful than hot', unable to stay in); cooling with a hose, shower, or a wooden channel of cold water is the accepted workaround, and one family cooled it enough for children.
stated by 8 visitors · Nov 2017 – Aug 2026Staffing
The facility is run by a female keeper/attendant whom at least five reviewers describe as friendly and accommodating ('okami-san', 'reception lady', 'kind mother figure', 'caretaker'); one reviewer nonetheless paid via an unattended fee box, suggesting the desk is not always manned.
stated by 6 visitors · Sep 2021 – Aug 2026Price
Adult day-use bathing is 800 yen per three reviewers (2019, 2020, and 2025 — the 2025 camper itemized it as 入浴料800円); one reviewer in Nov 2022 reported 500 yen, so the price may have varied. Several call the pricing reasonable for the area.
stated by 5 visitors · Sep 2019 – Oct 2025Water handling
The bath is free-flowing from the source (gensen kakenagashi), stated by five reviewers between 2019 and 2026; one calls it '100% natural kakenagashi'.
stated by 5 visitors · Sep 2019 – Aug 2026Outdoor bath & sauna
An open-air bath exists on the lower level by the campground (four reviewers, 2018-2025), but one day visitor in Oct 2025 said they found nothing resembling a rotenburo — so day-use access to it may not be obvious; no reviewer mentions a sauna.
stated by 5 visitors · Feb 2018 – Oct 2025Day-use visits
Day-use bathing is accepted (at least four reviewers bathed as day visitors, several while camping); no reviewer states the official hours, but two report being flexibly admitted outside them — one welcomed when arriving early, one let in after closing time.
