Yudanaka Onsen 湯田中温泉 — Nagano
Private open-air bath in your room
The renewed suites put a semi-open-air bath on the room, pouring free-flowing spring water — the private soak is built into the stay.
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.

Every guest room's unit bath runs on natural hot spring water here — a Taisho-era source found bubbling up through the riverbed sand — and the shared scenic open-air bath looks over the town.
A small family inn where the hinoki bath is yours alone: write your room number on the board when it's free and lock the door behind you. The water is the inn's own 100% natural spring.
Until 7pm the inn's bath runs on reservations only — pick a 55-minute slot at check-in and the hinoki bath is entirely yours, filled with natural spring water poured straight from the source: no heating, no added water.
