A cypress-built dry sauna located in the top-floor large public bath, filled with the rich scent of wood. From the reasonably spacious two-tier bench, the strong, dry heat from the stove envelops the entire body. It slowly warms you to the core and encourages deep sweating. Because the entire bathing area is tatami-mat flooring, you can relax from the ground up, and the sauna room windows open onto a calm space where you can feel the natural atmosphere of Yuzawa.

A mist sauna attached to the large public bath. Fine warm mist fills the room, gently wrapping around the entire body and warming you slowly. It is easy to breathe in, so even sauna beginners and those who do not like high temperatures can relax comfortably. The moist warmth hydrates the skin and throat, easing daily fatigue in a soothing relaxation space.

A refreshingly cold cold plunge bath located directly in front of the sauna in the large public bath. It uses tap water, but perhaps because of Yuzawa's clean water quality, the water feels relatively smooth on the skin. It quickly tightens the body after being heated deep in the sauna. The cooling sensation is pleasant, and even a few seconds of immersion provide a refreshing sense of clarity. Access to the calm outdoor-air bathing area in the changing room is also smooth, supporting a high-quality totonou experience.
