About
Suwa Onsen is a small bathhouse run by Uonuma city, built for popping in for a soak. It has an indoor bath, a rotenburo (open-air bath) and a sauna, and a cold plunge is mentioned by a visitor. The indoor bath and sauna were added in the 2023 fiscal year in the old rotenburo building, and the compact, barrier-free layout dates from that renovation. There is a free rest area where you can bring your own food, with a microwave and a water server. Towels are not included, but you can rent one.
