Guide
What visitors add
The water
The water is a turbid brown/ocher color — at least seven reviewers describe it (brown, reddish-brown, orange-brown); two note the tub steps are invisible through the murk, so watch your footing. Five reviewers also report a distinctive oil/petroleum smell.
stated by 8 visitors · Mar 2025 – Jun 2026Price
Non-Takasaki-residents pay 730 yen (three reviewers, Jun 2025 to Apr 2026; one adds that non-residents have no time limit). Takasaki residents pay a discounted rate: three reviewers from 2025 say 320 yen, while one reviewer (Apr 2026) says 310 yen — reports differ by 10 yen. Elderly resident discount of 200 yen is reported by two reviewers, who disagree on the threshold (one says 65+, one says 60+).
stated by 7 visitors · Jun 2025 – Apr 2026The water
Strongly salty chloride spring: one reviewer gives the classification as Na-Ca strong-salt chloride spring with iron, and at least five other reviewers independently report salty water or high salt content (one warns it may sting cuts).
stated by 7 visitors · Apr 2025 – Aug 2026Outdoor bath & sauna
There are two tubs — one indoor bath and one outdoor bath (rotenburo) — confirmed by four reviewers; two describe the rotenburo as small and neither tub as large. Two reviewers state there is no sauna (and one adds no jet bath, electric bath or carbonated bath either). One reviewer complains the rotenburo was full of insects (Nov 2025).
stated by 7 visitors · Apr 2025 – Aug 2026The water
Bath temperature is moderate — three reviewers report about 41 to 41.5 degrees C — and at least four reviewers emphasize the water warms you unusually strongly; one reports reception staff advise getting out every 7 minutes to avoid overheating because it does not feel hot.
stated by 6 visitors · Mar 2025 – Jun 2026For foreign visitors
Atmosphere note for out-of-town visitors: two reviewers (Jun and Nov 2025) separately report being yelled at by local regulars over closing the outdoor-bath door; one of them concluded the facility is unwelcoming to visitors from outside the prefecture. The clientele is predominantly local — at least four reviewers describe it as a locals' bath.
