Guide

What visitors add

Staffing

The bath is staffed by a woman at a traditional bandai (attendant booth); at least three reviewers describe her as kind or helpful. One reviewer (October 2020) reported her smoking a cigarette at the booth adjoining the changing area.

Day-use visits

Hours are unreliable per reviews: one reviewer (2019) says the men's bath is posted 4pm-9pm but he was let in at 3pm; one reviewer (2021) reports closing days as Thursday and Sunday; one reviewer (2018) found it closed during its listed hours, and another (2022) found it closed for boiler repair. Verify before visiting.

The water

This is a wood-fired sento (public bath), not a hot-spring onsen: three reviewers mention the wood-fired heating, and one says the water is soft groundwater pumped from deep underground.

The water

The bath is notably hot: three reviewers describe very hot water (one estimates about 43C and could only stay in about 5 minutes; one says it was scaldingly hot at opening until the attendant added cold water; the tub is split in two with one side kept hotter).

Towels, soap & lockers

Bring your own soap and shampoo: three reviewers report there are no showers and no shampoo/soap provided (old-style sento with buckets and hot/cold taps only), and one of them adds there are no lockers, only baskets, with belongings left on the floor in view of the attendant's booth.

Price

Admission was 450 yen according to a reviewer who visited around June 2025; an earlier reviewer (visit August 2021) paid 400 yen, so the price appears to have risen. One reviewer also notes the hair dryer costs 50 yen.
