The waters are a sodium chloride hot spring renowned for warming you to the core. The sauna features a genuine bona sauna with the heat source housed beneath the bench, creating a pleasant, high-quality humidity. Right in front of the sauna room, there is a pleasantly mild and cool cold plunge bath, allowing for an exceptional totonou experience with cold water and the refreshing outdoor air of the highlands.
A sodium chloride hot spring highly regarded for warming the body very well and helping you stay warm longer. Its mildly alkaline water is gentle on the skin and is also said to be effective for joint pain and recovering from fatigue. In addition to the large indoor bath, you can enjoy the ultimate bathing experience in the open-air bath, where you can take in panoramic views of Mt. Asama and the refreshing breeze.
A genuine bona sauna that houses the heat source beneath the bench, gently spreading soothing warmth that is kind to the skin. Because the stove is not exposed inside the room, it feels less stuffy, and the moist, high-quality humidity wraps your whole body in a gentle heat. You can also peek outside through a small window in the sauna room and enjoy a calm, leisurely moment.
A cold plunge bath prepared right next to the sauna room, with a mild and gentle coolness. Because it is not too cold, it is easy on the body, and you can soak for a while to cool down your heated skin. After getting out, you can head straight to the outdoor air-bathing area in the open-air space, making for a smooth and comfortable flow.
