A chloride cold mineral spring gushing from underground. The greenish hue of the water is the natural color of the hot spring components, allowing you to visually confirm its mineral richness. The chloride spring's high heat-retention effect keeps you warm after the sauna, warming your body from the core. Although the source temperature is low, the heated water gently envelops the skin and is expected to be effective for chronic muscle and joint pain, sensitivity to cold, and fatigue recovery. The indoor bath offers views of the seasonal scenery of Shimodago through large windows, and the open-air bath allows you to become one with nature while overlooking Mount Awagatake in a spacious setting.
