Kasane · 重ね

Kasane means layering. Of seasons, of rituals, of days that slowly settle into one another.

Each retreat is built from its place: a hot spring valley, a volcanic island coast, an ancient cedar forest, a Pacific shore of rice fields. The rhythm is the same wherever you arrive.

Homes that live like a retreat.

Kasane Residences are a small number of private homes inside our retreats. You own the home; we look after it, and everything around it, the way we look after our guests.

When you are away, your home can join the retreat's rental collection, or earn points to stay at our other destinations.
