A chloride cold mineral spring that gushes from underground. The greenish hue of the water is the natural color of the hot spring components, visibly rich in minerals. The chloride spring's unique insulating effect keeps you warm, continuing to warm the body from within after the sauna. Although the source temperature is low, the heated water gently envelops the skin and is expected to be effective for chronic pain in muscles and joints, cold sensitivity, and fatigue recovery. The indoor bath offers views of the seasonal landscapes of Shimodagou through large windows, while the open-air bath allows you to become one with nature while overlooking Mount Awagatake in an open space.
