At 1,000m elevation, the deep forest of Kitakaruizawa is all yours.
Breathe the crisp air of a forest turning red, take your time,
and find luxurious moments becoming one with nature.
THE FOREST SAUNA
Your Own
Forest Retreat
THE FOREST SAUNA is a private villa nestled in the highland forest of Kitakaruizawa at ~1,000m elevation. The high ground turns early — foliage typically peaks from mid-October. Sweat it out in the state-of-the-art barrel sauna, then step into the cold, clear air outside: the colder it gets, the deeper the calm. In winter, the forest is under snow. An extraordinary escape to reset your mind and body, far from the city.
