Sauna
In spring 2026, a Private Tent Sauna arrived at the very front row of Lake Kawaguchiko — an unobstructed seat to the view. It's the ultimate uninterrupted sauna experience, made possible only by a whole-villa rental set on 1,200 m² of private grounds.
"Totonou" (整う) is a Japanese term for the blissful, deeply relaxed state that follows the cycle of sauna, cold plunge, and rest — a feeling regular sauna-goers in Japan chase again and again.

The tent sauna sits in a private area just off the room's terrace. Its greatest feature is the sheer location — you can take in Lake Kawaguchiko and Mt. Fuji at the same time, right from inside the sauna. In the gentle heat of the wood stove, enjoy löyly at your own pace. As the wave of heat washes over you, the changing scenery of the seasons unfolds just beyond the window. Feel the energy of nature on your skin in this one-of-a-kind meditative space that leads you into deep relaxation.

Cool your heated body in the adjoining cold plunge. After sinking into water as clear as Mt. Fuji's underground springs, move on to the ultimate open-air rest on the spacious deck. A soft breeze crossing the lake, birdsong, the shimmer of the water's surface — senses sharpened by the sauna catch every breath of nature with striking clarity. Immerse yourself in a deep sense of well-being that only a space reserved for one group a day can offer.
