All 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 Facility was clean and comfortable overall. The Room had an ocean view and was spacious, and the washroom and toilet were also large, which was great. We enjoyed delicious meals for both breakfast and dinner. The flounder kamameshi was especially tasty, and the zenzai at the dessert buffet was a unique treat. After 5:00 PM, there were no day-use bath visitors in the large public bath, so we could relax comfortably. This is an Accommodation we would love to stay at again.

  • We chose the Hirame Kaiseki dinner. The sashimi, tempura, and kamameshi were all delicious—absolutely wonderful! The women on staff at the dinner venue were also very kind and attentive. Our child got full and left some of the kids’ set, but they spoke to us gently, which we really appreciated.The Onsen was also excellent, and our children even woke up early to enjoy a morning bath.When we went to breakfast in the 8:00 time slot, some items that had run out (fried chicken and “Chicken Chicken Burdock”) were not replenished, so we couldn’t try them, which was disappointing.Other than that, everything was great with no issues. We’d love to stay again someday.
