A cold plunge bath located right near the sauna room, with a solid depth reaching about thigh level. Its defining feature is a gentle, soft coolness that slowly seeps into the skin, making it comfortable even for those who do not like sudden temperature changes and allowing the body to sink in for longer. Fresh water is constantly flowing in, gently cooling down the heated body in a quiet corner of the large bath. After getting in, we recommend an outdoor air bath on the totonou chairs set up in the open-air bath area.
