The large public bath, Kei no Yu, comes with an open-air bath that lets you take in a panoramic view of the rich mountains of Kurobe Gorge stretching out before you and the clear waters of the Kurobe River flowing below. The spacious, open indoor bath can accommodate about 80 people and also offers views of the great outdoors. The water, drawn from the Kuronagi spring, is rich in metasilicic acid, which is also found in lotion, and is known as Tsubetsube Bijin no Yu, a skin-beautifying bath that leaves skin smooth and silky and gently melts away everyday fatigue from deep within.

The private bath, Saikan Sanyu no Yu, lets families and loved ones relax and enjoy the famous waters of Unazuki at their own pace in a private setting. This gentle, weakly alkaline skin-beautifying spring warms the body deeply and pleasantly eases daily stress. It offers the ultimate therapeutic bathing experience, allowing you to indulge in superb hot spring waters without worrying about those around you.
