Echigo-Yuzawa Onsen 越後湯沢温泉 — Niigata
Private open-air bath in your room
Some rooms have their own open-air bath, and the hotel states that every bath in the building — rooms included — uses source water.
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.

Three free reservable baths on the top floor. Thirty of the 86 rooms also have an open-air bath with natural onsen drawn in — but not every open-air-bath room is onsen (the Hanamizuki room is not, and rooms' indoor baths are not onsen), so check the room type name when booking.
Two reservable baths filled with 100% source water — Garaku no Yu is ¥2,200 for 50 minutes. The inn discloses that it combines some circulation to keep the temperature steady.
