Group Facility List
Karuizawa 365 Riverside Villa Happudai
A private forest stay wrapped in the sound of the river. A 170 m² private villa by the riverside, embraced by forest and light. Through a 5.5-meter-wide picture window, all you see is the forest through the seasons and the quietly flowing river. Laughter and even the sound of your dog’s paws running fade gently into the woods. Put down your phone and take a moment to breathe in the scent of the forest and listen to the river. Nature—and you—begin to feel restored, little by little. This is a stay that one day simply isn’t enough for. Enjoy a vacation-home lifestyle in the forest with your family and your dog.
Karuizawa 365 Forest Garden Happudai
A private, whole-house villa where you can fully enjoy life in Karuizawa and feel the beauty of nature in every season. Set on a spacious 350-tsubo property for complete privacy: play with your dog in the exclusive dog run in spring, enjoy BBQs in summer, relax in a hammock while admiring autumn foliage, and savor wine by the wood-burning stove in winter. The modern interior features an airy living room framed by large windows of about 7 meters, plus a deck for campfires and a covered outdoor area. Located slightly away from central Karuizawa in a serene and refined neighborhood, enjoy your own time surrounded by seasonal scenery and exceptionally quiet, crisp air.
Karuizawa 365 Play Garden Ohinata
A seamless connection for both mind and space. Play Garden Ohinata is one of Karuizawa’s sunniest spots—an inviting place that naturally brings out your playful side. A spacious garden that makes you want to run, and an interior that looks out onto it through large windows, flow together seamlessly in an open, airy layout. This flat, continuous space can also serve as a dog run, where your beloved dog can dash around freely—bringing smiles to family and friends as they watch. In this wonderful place where hearts feel seamlessly connected too, time slips by unnoticed, and the moments you share become unforgettable memories.
Karuizawa 365 Tree Nest Happodai
A private villa floating among the trees. Experience the luxury of doing nothing—from a bird’s-eye view. Tree Nest Happodai is a place to spend time as if you were a resting bird. Beyond the windows, leaves sway and specks of light shimmer as nature and time flow gently. In cozy spaces—like the raised living area that makes you feel like a squirrel or small bird, and an airy elevated floor where the breeze passes through—carefully chosen interiors soothe and refresh your mind. Put down your phone, take a deep breath, and surrender to the quiet with your dog. A hidden retreat that feels perfectly within reach. Stretch on the terrace, chat or read, or simply gaze into space—everything fits here. Embrace the forest and enjoy the luxury of doing nothing.
