Shibu Onsen Kokuya
Historic wooden ryokan with reservable private baths

Shibu Onsen 渋温泉 — Nagano
Reservable private bath
A family bath called Amatsumikawa — the River of Heaven — free for 40 minutes, fed by the inn's own blend of three Shibu sources.
A single stone lane in snow country, nine public baths, and wooden inns that have stood for centuries. The private bath works like this: you book it, it's yours. Door closed, steam up, nobody else's schedule anywhere near you. Take the late slot — night air on wet skin is the whole point.



Private-bath and water facts were checked against the property's official site and Japanese booking pages in November 2026. Room plans change — confirm the private bath is included in the plan you book.
