What they say
Michelin Selected
Michelin
Luxurious, sparsely decorated rooms look out over artfully framed views of the surrounding greenery, and the cuisine is made from freshly harvested local ingredients.
Tucked away
A place apart: the property is the destination.
On the Monobe River banks in Kami, surrounded by reforested hillside greenery.
The rooms
Riverside suites offer open-air hot-spring tubs on private timber decks, alongside tatami living spaces and dedicated listening lounges with vintage speakers.
The onsen
Soak slowly.
Stone soaking baths sit on wooden decks among the trees, filled with amber, isotonic sodium-chloride spring water.
At the table
Dining tables look out toward the river terrace, where seasonal Satoyama dishes arrive alongside music from vintage tube amplifiers.
How it began

Guided by the musical natural sign, the retreat restored degraded hillside terrain along the river and heats its springs with recycled cooking oil.
