A full-fledged high-temperature dry sauna located deeper inside the low-temperature room. Its double-door-like structure helps keep the heat in, so the powerful warmth envelops your entire body. In a calm space with the warmth of wood and no television, you can enjoy deep perspiration while facing yourself in silence.

A sauna that also serves as the antechamber to the high-temperature room. Although it is called a low-temperature room, the far-infrared effect warms the body thoroughly. It feels milder than the high-temperature room, making it ideal when you want to work up a sweat slowly over time. Passing through this room and heading into the even hotter room at the back is part of the facility's unique sauna experience.

A compact cold plunge bath that sharply tightens your body after the sauna. The water quality is excellent, and its gentle feel on the skin is a defining feature. The flow from the sauna is smooth, providing a refreshing cooldown experience. You can enjoy a luxurious Chichibu-style totonou routine that leads into outdoor air bathing while listening to the Arakawa River murmuring.
