Tsukiyono Onsen, Minakami, Gunma

Tsukiyono Onsen Mitsumine-no-Yu

Mitsumine-no-Yu is a simple, low-cost option for drivers who want a short soak in a small municipal bath. Go for the price and free-flowing water, not for extensive facilities or many washing stations.

Check before bathing

Opening hours
Open 10:00–19:30. Since July 1, 2026, admission is ¥600 for adults from outside Minakami and ¥300 for children. Closed on the third Wednesday of each month and January 1. The washing area is small because the source flow is limited.
Tattoo policy
The current town and tourism-association pages checked do not state a tattoo policy. Ask the facility before visiting.
