A private villa nestled among the trees. Enjoy the luxury of doing nothing from a bird’s-eye view.

Tree Nest Happodai is a place to spend time from the viewpoint of a resting bird. Beyond the windows, leaves sway and specks of light shimmer as nature and time flow gently. Enjoy a raised living area that makes you feel like a squirrel or a little bird, and an airy loft-like floor where the breeze passes through. In these cozy spaces, carefully chosen interiors will soothe and enrich your spirit. Put down your phone, take a deep breath, and sink into the quiet with your dog. A hidden retreat that feels perfectly within reach. Stretch on the terrace, chat or read—or simply do nothing at all. Savor the luxury of doing nothing, embraced by the forest.

Notice from the Accommodation

As of June 1, 2026, Karuizawa Town has introduced an Accommodation Tax. For Reservations made via IKYU, due to system limitations, the Accommodation Tax cannot be shown separately; therefore, our displayed prices have been revised to include the equivalent amount in advance. Meanwhile, Reservations made through our official website will be shown with a clear breakdown as “Accommodation Fee + Accommodation Tax.” Regardless of where you make your Reservation, no additional Accommodation Tax will be charged on-site, so you can stay with peace of mind at the displayed price only. We sincerely appreciate your continued patronage.
