Lavishly uses chloride spring water drawn from 1,400 meters underground in all baths. Especially in the open-air bath, you can enjoy the 'raw' source water free-flowing. Known as 'Beauty Skin Bath' due to its weak alkalinity, it has high moisturizing effects, with a smooth texture that gently envelops the skin. Due to the heat retention properties unique to chloride springs, your body stays warm even after bathing, making it hard to catch a chill. The main bath offers high-temperature springs over 42°C, stimulating the sympathetic nervous system and revitalizing body and mind. The sleeping bath allows you to enjoy a full-body bath at a lukewarm temperature. The men's bath features a cypress bath made from domestic high-grade solid cypress, allowing you to relax enveloped in the scent of cypress. From the open-air sky bath, you can overlook Gunma's famous peaks and enjoy a magnificent panorama of the four seasons, providing an exquisite hot spring experience.
