A Ryokan with detached guest rooms featuring open-air baths and ocean views of Kamogawa. Enjoy a moment savoring gourmet cuisine and Onsen.

Opened in August of Reiwa 4, our property features 10 private rooms, each with an Onsen open-air bath and a view of the sea. Enjoy an extraordinary moment as you take in the vast expanse of the Pacific Ocean, the lush greenery of the Mineoka Mountains, the sound of the waves, and the scent of the trees. The guest rooms promise a private stay in an infinity-like space where the sea and sky blend seamlessly. From the open-air baths and wooden decks, you can admire the "water basin," a landmark of Rian, which enhances the sense of unity with the ocean. Be captivated by the setting sun sinking into the horizon and the moon gently floating on the water's surface. Our cuisine is rooted in the traditional fisherman's dishes passed down in this region. Experience FUSION BOBO-CUISINE, which preserves the lineage of flavors while also offering visual beauty and the joy of eating. Indulge in truly delicious seafood dishes made possible by our origins as a fishmonger.

  • I stayed again for two nights, just like last time, after a six-month break.As before, everything was flawless, including the room and the Onsen.The hospitality was especially outstanding, and as someone in the service industry, I learned a lot.Thank you for three memorable days.

  • We stayed with our family of five to celebrate my husband’s retirement. Our daughter and her husband booked a separate Room and were happy they could relax. We were able to eat together in our Room, which made it a fun and memorable trip. The open, spacious bath was wonderful, and the silky water felt very pleasant. They also replaced our towels, which made our stay comfortable. Thank you for your hospitality. However, the dinner portions felt insufficient—I'm not sure what the main dish was supposed to be. It wasn’t visually appealing either, which was disappointing. The rice was also too soft... Breakfast had a good variety of side dishes, but the miso soup sardine dumplings were too heavy, with little depth of broth flavor... The rice also had many overly hard, crispy parts—perhaps because it was cooked in a pot... I think the meals should be improved.
