An alkaline simple hot spring gushing from 1,100 meters underground, known as the Beauty Bath. The water feels smooth and gentle on the skin, and you can experience the beautifying effect of smooth skin after bathing. The alkalinity softens keratin and helps to condition the skin. The warmth is gentle, providing a gradual relaxation from the core, with lasting warmth after bathing. The indoor baths include a variety of tubs such as the natural hot spring bath, plain hot water, electric massage bath, daily changing bath, jacuzzi bath, hot bath, and sit-down bath, allowing you to enjoy a variety of bathing experiences. The open-air bath also features a tsubo-yu, where you can leisurely enjoy the hot spring in an open space. It is expected to be effective for neuralgia, muscle pain, joint pain, sensitivity to cold, and recovery from fatigue.
