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 ocean views from the Room, the large public bath, and the dining area were outstanding—scenery we could have watched forever. There were very few guests, not only foreigners but also Japanese; only about five groups were dining at the same time, and the open-air bath in the morning felt completely private, so time passed at a wonderfully relaxed pace. If I had to ask for one thing: Rooms without a bath require using the large public bath, so I would have appreciated a carry basket for taking items with me. Also, my husband mentioned that having shaving soap in the Room would make morning grooming easier. The meals were delicious as well—we were extremely satisfied!
Yahoo!トラベルユー... 7/31/2026The views from the Room and the open-air bath were amazing, and I wished I could have stayed one more night to relax.Every dish at dinner was delicious and truly impressed me.The sweets were handmade with a wide variety, and the zenzai and uiro in particular were very tasty.I ate until I was completely full.I would love to stay again in a different season.
