Experience Awaji's seafood at Sumoto Onsen, a Ryokan with all rooms offering ocean views.

All rooms offer ocean views at this Ryokan with Onsen overlooking the Awaji Sea. The 180-degree panorama outside the window is truly breathtaking. Boasting a variety of rooms with different concepts by floor and a wealth of Plans. This is a highly recommended place for all generations to choose their own way of enjoyment.

  • Seaside View

    We were able to relax in a Room with a great view. Dinner was served in the Room, so we didn’t have to move and could take our time. The parking lot felt a bit far away. It seems there are many foreign staff members these days, and they provided courteous service. We would like to stay again.

  • On my first trip to ...

    On my first trip to Awaji Island, I enjoyed a relaxing Multiple Night Stay for two nights. Located in the center of the island, it was convenient for getting around from the northern area all the way to the Tokushima side.The view was wonderful—nothing but the sea—and the meals were excellent. They also changed the menu on the second day, which I really appreciated.One suggestion: it would be helpful to have a luggage rack for suitcases.
