The bath

What you’ll find

A cheap, no-frills community bathhouse (single indoor tub, 2-hour 440 yen entry, famous cheap motsuni-set meal) whose posted 'no disinfectant' claim is repeatedly contradicted by reviewers smelling chlorine and seeing debris on the water, and which refuses tattooed guests.

Guide

What visitors add

The water

One reviewer cites the posted analysis: alkaline simple spring, source temperature 30.8°C, pH 8.8, colorless and transparent, no added water but heated. Three reviewers describe a smooth/lotion-like slippery feel on the skin; one reports fine bubbles clinging to the body (suggesting carbonation). Bath temperature is disputed: three reviewers put it around 41°C, three describe the water as lukewarm, and one calls it comparatively hot — likely varying by visit.

Price

Adult admission is 440 yen (tax included) for a 2-hour session — stated by nine distinct reviewers between Apr 2025 and Jul 2026 (one quotes it as 400 yen ex-tax). One reviewer (Jun 2026) instead states 550 yen, conflicting with the others. One reviewer notes elementary-school children pay 330 yen.

Outdoor bath & sauna

Indoor bath only — no outdoor bath and no sauna. Six reviewers describe a single indoor tub (one states explicitly there is no rotenburo or sauna); capacity estimates range from 5-6 people to 10+. Washing stations: two reviewers count 5, one counts 4; one reviewer notes queues form when more than about 5 bathers are present, and one complains of weak showers.

Towels, soap & lockers

Shampoo and body soap are provided despite the low price — confirmed by four distinct reviewers; one also notes a single hair dryer. Valuables lockers take a 100-yen coin that is NOT returned — reported by four distinct reviewers (one advises using the free clothes baskets and not bringing valuables); one notes the shoe shelves are open and unlocked.

Day-use visits

Bathing is sold in 2-hour sessions (five reviewers mention the 2-hour limit alongside the 440-yen price). One reviewer says it is open until 19:00 on a Sunday; another arriving just after 18:00 on a Sunday found the dining area already closed, bath only.

stated by 6 visitors · Aug 2025 – Jun 2026

Water handling

The bath appears to be recirculated/filtered, not free-flowing: one reviewer was told it is 'recirculating filtration with no added water', another observed water drained from the bottom and recirculated and suspects a switch away from an advertised kakenagashi, and a third says it may be recirculating though water pours in generously. Four distinct reviewers (Mar 2025–Jul 2026) report a chlorine/disinfectant smell; one notes the posted spring analysis claims no disinfectant is used, contradicting what they smelled.
