Enjoy an intense sauna experience with a tent sauna heated over 100°C and self löyly, then cool down with a refreshing dive into the natural waters of Lake Tazawa, the deepest lake in Japan.
Floating between the lake, sky, and vast nature creates an unmatched feeling of relaxation — a truly special totonoi experience. Totonoi is the calm, floating state of mind and body
after sauna, cold water, and rest.
This is a fully private sauna, inspired by traditional Finnish lakeside saunas, where you can relax freely at your own pace.
