A wooden large bath in the Rococo style that retains the atmosphere of the Meiji era, this is a bath you can actually soak in and a Registered Tangible Cultural Property of Japan. Fresh 100% pure hot spring water bubbles up naturally from between the rounded stones laid on the bottom of the tub in this extremely rare free-flowing spring known as a spring that wells up from beneath your feet. The four tubs each have slightly different temperatures, and the water is characterized by its gently warm, soft feel. In this space wrapped in silence, you can enjoy luxurious therapeutic bathing time, simply facing the hot water itself.

A spacious, open large bath made entirely of Japanese cypress, filled with the refreshing aroma of wood. It is equipped with washing areas such as showers and faucets, and also includes a rustic open-air bath where you can feel the murmuring of Hoshi River and the breath of the mountains on your skin. You can leisurely enjoy high-quality natural free-flowing hot spring water with 100% source water, on a time-sharing basis (women from 3:00 p.m. to 8:00 p.m., men from 8:00 p.m. to 7:00 a.m. the next morning).

A small, atmospheric large bath quietly standing right beside the clear stream of Hoshi River. In the suitability assessment conducted by the Japan Natural Hot Spring Examination Organization, it received perfect scores in all six categories, including the source water and the water supply and drainage system, making it an exceptionally pure and natural famous bath. The water feels remarkably mellow and soft on the skin, and during day-use bathing hours it is open as the women's-only Gojin-buro.
