This natural hot spring uses the private source Suijin no Yu, which springs from the land of Suijin-sama, the guardian deity of Toshijima. Gentle on the skin and rich in heat-retention benefits, this chloride spring helps keep you warm for a long time after bathing and prevents you from getting chilled. The large public bath is in a superb location on a hill 30 meters above ground, overlooking the islands of Toba Bay. While gazing at the ever-changing sea, you can enjoy an exceptional sense of relaxation.

A luxurious private reservable indoor bath surrounded entirely by hinoki wood. The soothing scent of hinoki that fills the bathhouse brings deep relaxation like a forest bath. From the large windows, you can take in exclusive views of Toshijima's beautiful sea and sky, and enjoy blissful bathing in a private space without worrying about anyone around you.
