Sauna
In spring 2026, a private tent sauna opened in a prime lakeside setting overlooking Lake Kawaguchiko — an unobstructed seat to the view. It's a completely private 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 state highly valued in Japanese sauna culture.

The tent sauna sits in a private area just off the room's terrace. Its defining feature is its exceptional location — you can enjoy views of both Lake Kawaguchiko and Mt. Fuji from inside the sauna. In the gentle heat of the wood stove, enjoy löyly at your own pace. As the heat gently builds, 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.
