Hoshinoya Karuizawa

A stream runs through the property, wild birds nest in the forest outside your window, and some floors are heated by the geothermal spring below your feet. This ryokan-inspired resort sits about an hour from Tokyo in the hills around Karuizawa, built around an onsen and a small lake, with contemporary villas that manage to feel genuinely quiet. The spa, the kaiseki dining room, and most of the guest terraces all face the trees.
