Highlights
Jet BathAbout
The main bath here is rare for Japan: a large indoor bath that can be fully opened to the air, facing Lake Toya, with an open-air rotenburo alongside it that puts you right at the water's edge. There is also a jet bath, a cypress jet bath, a lie-down bath and a floating bath, plus a self-loyly sauna with lake views from inside. It is a full resort hotel on the lakeshore, with day-use bathing open on a limited schedule rather than year-round.
