Kokumin Shukusha Oojou
Yamaguchi Prefecture/KudamatsuAll rooms offer ocean views, with an Onsen that blends seamlessly with the sea for a truly relaxing experience.
A Property with all rooms offering ocean views, situated on a hill overlooking Kasado Bay. Fully renovated in 2016, it has been reborn as an even more charming destination. The views from the Onsen are spectacular, featuring an open-air bath with a panoramic view of the Seto Inland Sea and an infinity bath that seamlessly blends with the sea and sky, offering an unparalleled sense of openness and breathtaking scenery. For dining, enjoy seafood dishes that combine Japanese and Western styles, made with an abundance of fresh ingredients from the natural harbor, including the specialty "Kasado Flounder." Embark on a journey to Yamaguchi, where the sea meets the heart.
The Room was spacious with a great ocean view, and both the meals and the Onsen were excellent. Here are a few highlights: - We chose dinner from 17:30, and one alcoholic drink was free. - The flounder tempura was light and fluffy, and absolutely delicious. - Dinner was served as a course meal, while dessert was offered buffet-style—such a luxurious setup. - The ocean view from the large public bath was wonderful, and all the showers and hair dryers were ReFa products. - What impressed me most was how thoroughly cleaned everything was. Although the Room itself didn’t seem particularly new, it was spotless—especially the washbasin area, which looked older but had no water stains at all and gleamed in every corner. It made our stay very comfortable. There were many great points like these, and we were very satisfied with our stay. Thank you very much.
Yahoo!トラベルユー... 9/23/2026I had visited before for a day-trip Onsen and already knew the baths were great, but the view from the Room was outstanding as well.The flounder sashimi was very fresh with a pleasantly firm texture and was absolutely delicious.I would love to stay here again.
