Jozankei Onsen 定山渓温泉 — Hokkaido
Private open-air bath in your room
High-floor rooms with view baths of real Jozankei onsen water, in the valley's biggest hotel — pick a room type with the onsen view bath.
And the bath? It's in your room. Not down a corridor, not on a sign-up sheet. Run it before dinner. Run it again at midnight. Wake up and get straight back in — nobody's timetable touches you here.
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.

Forest cottages and terrace rooms with their own open-air baths, filled straight from the source — a big Tsuruga resort an hour from central Sapporo.
Every room has its own hinoki onsen bath, and four reservable open-air baths are free to use as often as you like — a Kyoritsu resort in the Jozankei valley.
Most rooms look over the valley through a wall of glass with an onsen view bath beside it — the hotel dug for three years to find its own source.
