The water
Free-flowing (kakenagashi)
PartlyThe bath is source-fed, but low flow means it drains via an internal siphon rather than a true continuous overflow, and some visitors feel it doesn't really deliver the classic kakenagashi feel.stated by 4 visitors · Oct 2019 – Nov 2022
Spring type
Alkaline simple onsenThe spring is classified as an alkaline simple (low-mineral) hot spring, giving a mild, silky feel.stated by 3 visitors · Mar 2020 – Nov 2022

Guide
What visitors add
Price
Admission (when operating) is a 100-yen cooperation fee, paid cash into a box at the entrance (12 reviewers state 100 yen; 2 explicitly describe the fee box).
stated by 12 visitors · Oct 2019 – Nov 2021Day-use visits
The facility has been repeatedly reported closed: 10 reviewers between Mar 2022 and Oct 2024 found it shut, citing a drop in source temperature and finally the spring drying up; the most recent review (Oct 2024) says it is closed because the source ran dry. One reviewer found it quietly reopened in Oct 2022, but with lukewarm water. Verify current status before visiting.
stated by 11 visitors · Mar 2022 – Oct 2024Towels, soap & lockers
No soap, shampoo or towels are provided — five reviewers say to bring your own (one gave up bathing for lack of a towel).
stated by 5 visitors · Jul 2020 – Nov 2021Water handling
Three reviewers call it source kakenagashi; one detailed reviewer says the rebuilt facility dropped the old recirculation and chlorine but drains via a bottom siphon rather than overflow, so surface scum can linger, and one other notes flow volume is low.
stated by 4 visitors · Oct 2019 – Nov 2022Outdoor bath & sauna
Indoor bath only — one reviewer lists the entire facility as entrance, changing room, toilet and one indoor bath; one other says the tub is full with three people. No reviewer mentions a rotenburo or sauna.
stated by 2 visitors · Oct 2019Staffing
The bath is unmanned and self-service: one reviewer notes there is nothing but an entrance, changing room, toilet and indoor bath, and one other relays local etiquette — open the tub lid yourself, close it and turn off the lights when leaving.
