Shibu Onsen Kokuya
Historic wooden ryokan with reservable private baths

Shibu Onsen 渋温泉 — Nagano
In-room bath + reservable private bath
Suites whose own baths pour straight from the source — the Yoimachi Suite's open-air bath under the stars — plus a reservable sauna-and-onsen course.
A single stone lane in snow country, nine public baths, and wooden inns that have stood for centuries. You get both kinds of private here — a bath of your own, and reservable ones for the long soak. Most guests use both before checkout. You probably will too.



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.
