An alkaline simple hot spring gushing from 1,100 meters underground, known as 'Bijin no Yu' (Beauty's Bath). The water feels smooth and gentle on the skin, leaving it silky after bathing, providing a beautifying effect. The alkalinity softens keratin and helps to condition the skin. The warmth is gentle, gradually relaxing you from the core, and the warmth retention continues after bathing. The indoor baths include a variety of options such as the natural hot spring bath, plain hot water, electric massage baths, daily special baths, jacuzzi baths, hot baths, and sitting baths, allowing you to enjoy a bath-hopping experience. The open-air bath also features tsubo baths, allowing you to enjoy the hot springs in an open and relaxing space. It is expected to be effective for neuralgia, muscle pain, joint pain, sensitivity to cold, and fatigue recovery.
