An award-winning “transparent architecture floating in the forest,” featured in numerous media outlets worldwide.
Step inside, and an untouched forest stretches out before you with nothing to block your view. The space—furnished with carefully selected, high-quality pieces that blend with nature and featuring a piano—feels like a refined treehouse. In the morning, you’ll wake to dappled sunlight and the gentle presence of birds and squirrels—. This is a one-of-a-kind experience: even indoors, you’ll feel as if you’ve become part of the forest. On the grounds, we also offer a separate annex for stargazing and a jacuzzi building. In addition to booking the main building exclusively together with these spaces, you may also stay in just the annex + jacuzzi building (kitchen included, no curtains, BBQ option available), for a private retreat where you can enjoy Karuizawa’s forest all to yourself. Spend an extraordinary moment in this architectural masterpiece as you quietly connect with nature.
A Hotel nestled in the forest where you can enjoy an extraordinary escape. It has floor-to-ceiling glass walls, but privacy didn’t feel like much of a concern. Before staying, I thought it might be a bit cold, but the room was properly heated and very comfortable! The staff were kind and helpful as well. I’d love to stay again.
yy0310 3/22/2026The natural scenery of Karuizawa spreading out beyond the windows and the open, skeleton-style layout were an unforgettable experience.Day, night, and morning all felt special—I didn’t want to check out.I especially loved the bath on the third floor.I’d love to stay again around spring next time.

Introduction of the Accommodation
An extraordinary retreat, secluded from the outside world and embraced by Karuizawa’s primeval forest.
In a minimalist glass-walled space, with the rustle of the wind and birdsong as your soundtrack, immerse yourself in the forest. This is a luxurious hideaway designed to let you fully enjoy an extraordinary experience—feeling outdoors while staying inside.
Enjoy architectural beauty in harmony with nature
A simple, uncluttered design that feels as if only the building’s frame is floating in the forest. Built with the felling of just three trees, it offers the sensation of standing in the woods even while indoors. Take a break on the stair landing or soak in the scenic-view bath. Its multi-level spatial design lets you enjoy Karuizawa’s forest from a variety of angles as your height and perspective change. Winner of numerous architectural awards in Japan and abroad, and featured widely in media and magazines.
Another hidden retreat, close to the forest
A separate annex, quietly nestled deep within the primeval forest a short distance from Wa no Ie. With only a single pane of glass between you and nature, it offers a rustic, tent-like experience. Enjoy the comfort of the refined main house, and the annex that draws you into nature like camping. Experiencing both is what makes a stay here truly special. By reserving it as an exclusive rental together with the main house, you can enjoy Karuizawa’s forest with greater freedom and luxury.
Villa with a Semi-Open-Air Jacuzzi
A jacuzzi villa surrounded by forest is also available. Enjoy a blissful moment as you soak in the warm water, immersed in the presence of an ancient woodland. *The detached villa and jacuzzi villa can be reserved together with the main Wanoie building as a single Reservation. Ideal for group stays, this is a private retreat where you can enjoy Karuizawa’s forest all to yourselves.
