A dry sauna with the lighting reduced to an absolute minimum, ideal for meditation. In the silence, you can face yourself while being enveloped in gentle heat reminiscent of a wood-burning stove. If you're lucky, you may even spot a Blakiston's fish owl through the window.

A spacious dry sauna with a large window overlooking the clear flow of the Shibetsu River. Self-löyly is available, and the aroma of wood spreads through the room along with the steam. With the murmur of the river as your BGM, you can fully enjoy a luxurious sauna time.

A moist mist sauna that makes use of steam from the spring source. The high-humidity environment gently moisturizes your skin and throat while warming your body from the core. Even those who are not fond of dry saunas can relax here at a leisurely pace.

A luxurious cold plunge bath using chilled spring water. The water, which contains hot spring minerals, is gentle on the skin, and its crisp coldness is refreshing. In the spacious tub, you can cool your whole body thoroughly.

A wild open-air cold plunge bath with a platform set up in the Shibetsu River flowing right in front of the inn. The experience of surrendering yourself to the clear stream itself takes your sense of unity with nature to the extreme. You can feel the river's temperature, which changes with the seasons, directly.
