Indulge in the luxury of doing nothing—an extraordinary escape within world-renowned architecture.

An award-winning “transparent architecture that blends into the forest,” recognized by architectural prizes in Japan and abroad. A one-of-a-kind masterpiece, featured repeatedly in the media. 【The ultimate luxury—inside extraordinary architecture】 Wake up to dappled sunlight and birdsong. In season, squirrels may even stop by to say good morning from the 3rd-floor bedroom. Outside the windows stretches an untouched forest with nothing to block your view; at night, only silence and a sky full of stars remain. To preserve nature as much as possible, only three trees were felled during construction. Put power and screens aside for a while—and do nothing. That time is the greatest luxury here. 【Up to 3 bedrooms—ideal for multiple families】 Perfect for a quiet weekend for a couple and their dog, or for 2–3 families / 2–3 generations traveling together, or gatherings of 4–6 friends. By adding the optional detached annex “Ya no Ie,” you can expand to a 3-bedroom layout and accommodate up to 10 guests. It’s also popular as a “secret base” just for kids. 【Most popular: Private Chef Plan】 Authentic Italian cuisine sourced directly from renowned nearby restaurants, prepared at your table in this architectural masterpiece. We also offer a more casual catering Plan. As dining out or shopping requires driving, we highly recommend considering the Private Chef option for dinner. 【The luxury of slowing down】 Time spent here is not simply a trip to look at scenery—it’s a journey inward, toward yourself, your family, and close friends you can truly relax with. Deep conversations born from stillness; bonds that grow stronger in unhurried moments; time to remember what matters most—things left behind in an ever-accelerating world. These moments at Wa no Ie are one of today’s greatest luxuries. 【Enjoy nature with an immersive stay】 A car is essential to reach central Karuizawa or convenience stores. The building also prioritizes design over practicality in its structure. But that is exactly what makes it so special: stepping away from everyday life and being surrounded by nature. For experienced travelers who embrace every bit of “inconvenience,” as well as children seeking adventure, this will be a once-in-a-lifetime memory. There are many stairs throughout; if you’re staying with children or pets, we can install baby gates free of charge for your peace of mind.

  • From the moment we arrived and stepped into the forest, we were captivated by the beautiful architecture. Lush greenery stretches as far as the eye can see, and the space—where white walls blend perfectly with tasteful furnishings—made us feel happy just being there.What impressed us most was the top-floor bedroom and the glass-walled bath. It felt as if we were floating in the forest, and spending time surrounded by nature was an unforgettable experience.The staff were wonderful—always attentive and courteous—which made our stay comfortable and worry-free from start to finish.We visited with our dog this time, and it was truly dog-friendly. Our pet stayed relaxed throughout and seemed to enjoy every moment.Above all, a morning walk through the forest is exceptional. The clear air and peaceful silence created a special kind of time that’s hard to find in everyday life.A place we would love to return to—and one we can wholeheartedly recommend.

  • 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.

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 help you fully enjoy an extraordinary experience—feeling outdoors while staying inside.

Exterior

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 many angles by changing your height and viewpoint. Winner of numerous architectural awards in Japan and abroad, and featured widely in media and magazines.

Exterior

Another hidden retreat close to the forest

A separate annex, quietly nestled deep in the primeval forest a short distance from Wa no Ie. With only a single pane of glass between you and nature, it offers a wonderfully rustic atmosphere—like staying in a tent. Enjoy the refined comfort of the main house and, in the annex, an immersive, camp-like retreat into nature. Experiencing both is what makes this stay truly special. By reserving the main house together for exclusive use, you can enjoy Karuizawa’s forest with even more freedom and luxury.

Villa with a semi-open-air jacuzzi

Ideal for group stays, this is a private retreat where you can enjoy Karuizawa’s forest all to yourself.*
