Earthboat Kitakaruizawa

Gunma Prefecture／Agatsuma District
Vacation rental

A private outdoor Hotel at the foot of Mount Asama, surrounded by deep forest and a pond

A private cabin available for exclusive rental, nestled in a historic villa area of Kita-Karuizawa. On the grounds, you’ll find an Earthboat by a pond reflecting the surrounding trees, along with a landscape shaped by stones formed through Mount Asama’s volcanic activity. Each cabin features a private sauna. Choose between a wood-burning sauna you heat yourself by adding firewood, or an electric sauna warmed at the touch of a button to suit your stay. You’ll also have access to a cold plunge bath, an outdoor relaxation area, and an outdoor living space for BBQs and campfires. Pets are welcome in all cabins. Warm up in the sauna and enjoy a luxurious day away from everyday life, surrounded by crisp highland air.
