An Accommodation where architectural beauty and nature blend in harmony—a place to escape the everyday and do nothing.
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.
While looking for an Accommodation where we could stay with our dog, we discovered “Wa no Ie” and stayed there as a family.It’s surprisingly easy to find pet-friendly Hotels, but since we were going to Karuizawa, we wanted a place that truly felt luxurious and where we could enjoy time with our pet both indoors and outdoors. That’s when we found Wa no Ie—an outstanding piece of architecture surrounded by nature—and after seeing the photos, we decided almost immediately.When we arrived, the harmony between the building and the natural surroundings was even more beautiful than in the pictures. The greenery visible through the windows and the way light streamed in made it an incredibly comfortable space.Because we were traveling with a child and a dog, our only concern was the number of stairs. However, before our stay they had already set up baby gates for us, so both our child and dog could relax safely without any worry of falling. We really appreciated this thoughtful attention to detail.The interior was spotless, and the area around it was truly quiet. Away from the bustle of town, it felt like we were the only ones in the forest—something I personally loved.In the morning, I woke up naturally with sunlight and found myself thinking, “How long has it been since I last woke up like this?” My wife and child baked sweets and played games while our dog lounged with us—it was a place where you end up wanting to enjoy simply spending time there rather than going out sightseeing.If possible, I honestly wished we could have stayed for several more days—living there while working remotely.A private rental that offers nature, luxury, and an environment where you can stay comfortably with your pet is hard to find. We would absolutely love to stay here again whenever we visit Karuizawa. Thank you for such a wonderful time.
まかべたろう 9/10/2026The manager was incredibly friendly and considerate, which left a strong impression on us.At the beginning, they carefully explained how to use the Room, but it wasn’t just minimal necessary conversation—they spoke kindly with everyone, including our children, giving us a warm start.We added catering for dinner; although it should have ended with delivery, the manager kindly went out of their way to cook the pizza for us as well, and it was absolutely delicious.They also mentioned that with a private chef service, you can have even more authentic dishes cooked on-site. Given this level of quality and hospitality even with catering, we’re very curious about that option too.The building is unique, but the Room itself is well arranged and easy to use—when we entered, everything was ready right away in a comfortable environment.

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.

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.

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
A private Jacuzzi annex surrounded by forest is also available. Relax in the warm water and enjoy a blissful moment while feeling the presence of the primeval woods. *The detached annex and Jacuzzi annex can be reserved together as a set with the main Wanoie building. Ideal for group stays, this is a private retreat where you can enjoy Karuizawa’s forest all to yourself.*
