Guide

What visitors add

Price

Adult admission is 350 yen — cited by twelve distinct reviewers (Mar 2025 – Apr 2026); one adds children pay 250 yen, one that admission with rest-room use is 550 yen, and one returning after 20 years was surprised the price had not changed.

stated by 12 visitors · Mar 2025 – Apr 2026

Day-use visits

The facility CLOSED for repairs in April 2026 and was still closed as of 20 Jul 2026 with no announced reopening date: eleven distinct reviewers (Mar–Jul 2026) mention the closure; one who asked reception was told the 40-plus-year-old hot-spring piping needs repair and the restart date was undecided; closure was first announced for Apr 1, one Apr 5 visitor found it still intermittently open due to contractor delays, and an Apr 11 reviewer reported closure from Apr 13.

Towels, soap & lockers

No soap, shampoo or towels are provided — bring your own: eleven distinct reviewers say so. Four of them explain that the calcium-rich water prevents soap from lathering (one says you probably should not even use soap; another jokes that soap does lather fine if you bring modern body soap); one reviewer says toiletries can be bought at reception.

The water

The water is lukewarm: nine distinct reviewers describe nuru-yu — those giving numbers put the source at about 41°C and the tub at about 39–41°C, suiting long soaks; several note it keeps you warm long afterwards, while two winter visitors found it too cool. Smell reports conflict: two reviewers noticed a faint sulfur smell, one says no smell.

Water handling

The bath is gensen kakenagashi from the facility's own self-welling (jifun) source: eight distinct reviewers (Jan 2025 – Apr 2026) say so, two of them describing water visibly overflowing the tub.

stated by 8 visitors · Jan 2025 – Apr 2026

Towels, soap & lockers

There are essentially no showers: six reviewers of the men's bath report no shower at all (3 washing stations with mixing taps, weak flow — one scoops from the tub with a bucket instead); on the women's side two reviewers report only one of the three washing stations has a shower head and it ran cold water only.
