A designer villa with a treehouse and sauna, nestled in the vast forests of Kita-Karuizawa

Nestled on the northern foothills of Mt. Asama, Kita-Karuizawa is known for its cool, refreshing air. This designer villa—limited to one group per day—was created in an extraordinary setting: a vast private woodland of about 1,000 tsubo with a stream running through it. The open single-story home (3LDK) offers over 100 sqm of space and accommodates up to 10 guests, providing a luxurious retreat perfect for an unforgettable getaway with your loved ones. The symbol of this Accommodation is the “treehouse,” accessed via a suspension bridge from the wooden deck. Surrounded by the untouched forest of Kita-Karuizawa, stepping into this hidden treetop hideaway brings an exceptional sense of immersion—feeling truly at one with nature. At night, enchanting lights and the glow of a campfire illuminate the trees, drawing you into a fairytale-like world of quiet serenity. On-site, you’ll also find an authentic Finnish sauna by HARVIA and a cold plunge bath with chiller support—even suitable for single-digit water temperatures (°C). Outdoor relaxation wrapped in the scent of pristine woods at Mt. Asama’s foothills and the natural sound of flowing water delivers an unparalleled sense of deep renewal found only here. Cross the wooden deck and open the treehouse door to discover a secret base that brings out the child in everyone. Immerse yourself in the magical forest scenery of Kita-Karuizawa and enjoy an extraordinary escape to your heart’s content.

A treehouse nestled in a 3,300 m² forest—an intimate, quiet retreat with a sauna.

Set in a private 1,000-tsubo forest, the greatest highlight of COCO VILLA Kita-Karuizawa 01 is its “treehouse” floating beyond a suspension bridge. The moment you step inside, it sparks a sense of adventure for adults and becomes an instant secret hideout that kids will love. At night, gaze up at the starry sky by the campfire for truly magical memories. The newly built single-story home (over 100 m²) is exceptionally comfortable, and the property also features an authentic HARVIA sauna. Both adults and children can leave everyday life behind and immerse themselves in a fairytale-like world. You can also book both this villa and the neighboring Villa 02 together for an even more special stay with a larger group.
