Tendo Onsen Health Center Nozomi

Indoors there's a main hot tub and a cooler one to ease into, and outside a rectangular open-air bath holds around ten people; there's no sauna or cold plunge. The water runs clear and faintly salty, with a soft trace of sulfur. This day-use complex is certified as a hot-spring health-promotion facility, pairing the baths with a training gym, an indoor onsen pool and an exercise studio. There's also ganbanyoku stone-bed bathing, a reservable family bath, and a seasonal foot bath and drinking fountain open April through November. It sits between Tendo and Higashine along the Midare River, with a restaurant on site and a spring view of Mount Gassan from the studio.
