Shoraiso

A Nagano valley ryokan whose name translates as "wind through the trees in the mountains," which tells you exactly the kind of stay they're selling. The main draw is a series of baths, indoor, outdoor, communal, and private, that the region has been perfecting for centuries. Rooms are traditional Japanese style: tatami, translucent screens, low furnishings, arabesque archways, and dark wood throughout. A lounge bar opens onto a garden for the intervals between soaks. It holds a Michelin Key.
