Gero Onsen 下呂温泉 — Gifu
In-room bath + reservable private bath
Four reservable family baths, plus annex rooms with their own open-air baths — the inn delivers undiluted source water to its family baths and room baths alike.
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.
