- Kamogawa Onsen Rian
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.
It was a wonderful, very quiet Onsen Accommodation with a great sense of privacy. As it has only been a little over four years since opening, all the Facilities are new and feel very pleasant. The open-air bath had water that warmed us through to the core, and we enjoyed it many times.The seafood-focused meals were delicious for both dinner and breakfast, and the portions were just right for us. Nothing overly elaborate—just gentle dishes that highlight the quality of the ingredients. The spiny lobster in particular was excellent among the sashimi.The staff member who looked after us was also very kind, making our stay extremely comfortable. Thank you very much.Since it’s not far from central Tokyo, we would love to visit again.
bonissimo 9/23/2026I stayed for one night during the Obon holiday period, and it was a truly wonderful stay. With only 10 Rooms, the Accommodation was very quiet and private, and I hardly ran into other guests during my stay. The Room was spacious and spotless, and the open-air bath in the Room was very relaxing, allowing me to unwind at a leisurely pace. The food was also excellent, and I was extremely satisfied.
