A large theater-style sauna room equipped with authentic far-infrared heaters. The tiered bench layout lets you choose the temperature zone that suits you best, so you can relax and enjoy sweating at your own pace. With the far-infrared effect gently penetrating heat deep into the body, this is Yumominosato's main sauna, delivering a refreshing sense of revitalization.

A low-temperature sauna where you rub salt onto your body before entering. While gently warming the body, the osmotic effect of the salt helps support the removal of waste from the skin. By massaging the salt in softly, your skin feels amazingly smooth after bathing, making this a highly soothing space with excellent skin-beautifying benefits.

A refreshing cold plunge bath located right near the sauna room. It gently tightens your body after sauna use and brings a crisp, refreshing feeling. The clean tub and smooth flow into the outdoor area for open-air bathing are also part of its appeal. It supports your path to totonou with a pleasant cool-down.
