What they say
One Michelin Key
Michelin
Shoraiso’s name, meaning ‘wind through the trees in the mountains’, perfectly conjures the luxe onsen tranquility on offer here in the Nagano valley.
Somewhere quiet
Away from the crowds. Getting around takes intention.
In the historic hot-spring streets of Yudanaka, seven minutes on foot from Yudanaka Station.
The rooms
Each suite features tatami matting, private courtyard gardens, and a dedicated open-air bath fed continuously by natural thermal springs.
The baths
Soak slowly.
Mineral springs feed private suite tubs and neighboring Momoyama-buro, built from cedar and keyaki without nails under coffered ceilings.
At the table
Seasonal Shinshu beef kaiseki arrives in private dining rooms, while Lounge Den pours drinks beside a wood stove.
How it began
After a 2021 fire destroyed the original historic annex, master carpenters rebuilt the property in 2024 using pure sukiya woodworking traditions.
