A spacious public bath that combines a large indoor bath overlooking the courtyard with an open-air bath surrounded by the rich natural beauty of the rear mountain. The spring water is a simple sulfur spring with a high alkalinity of pH 9.1, and its silky, lotion-like texture is its signature feature. You can experience the double beauty benefits of its gentle cleansing effect, which softly removes dead skin cells, and the natural moisturizing component metasilicic acid. Enjoy a luxurious bath 24 hours a day in the fresh air, warming you through to the core.

An open-air bath exclusively installed in select guest rooms. The tub is constantly filled with fresh, free-flowing simple sulfur spring water directly from the source, with no water added and no heating. In a private setting, you can enjoy the finest silky beauty bath all to yourself, without being disturbed by anyone. Soak in a famous hot spring whenever and for as long as you like, and savor every moment of blissful private time to your heart's content.
