Day-trip bathing

Overnight stay only

The Pacific below the windows and the shinkansen still warm behind you — the closest real onsen escape from Tokyo. 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.

What Japanese guests say

Translated from Japanese guest reviews — the texture English roundups rarely carry.

Guests keep coming back to: the water itself · the food · the quiet

“The ocean looked a bit distant from the top floor. Since the surrounding area is a residential neighborhood, I couldn't really enjoy the view from the balcony with the open-air bath. The room was reasonably relaxing...”

“Clean, and the bath was open-air. The water quality, in particular, was outstanding. It was a pleasant stay. Way cheaper than expected. Stayed for one night in July 2020. Review for guests only. 10/10 (Very good). Also, 2020...”
