Only the two second-floor rooms (Satsuki and Yamabuki) have a private bath — an ordinary indoor tub, but the water that comes out is onsen. Day-trip bathing is not offered.
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.
