A property that combines traditional Sukiya architecture with retro-modern style, featuring private open-air baths in all rooms.
All rooms are detached suite rooms with open-air baths. Located on a vast property of 4,000 tsubo, this exclusive retreat consists of only twelve detached accommodations, all of which are suite rooms. Each room combines traditional Sukiya-style architecture with retro-modern design and features an open-air bath with natural hot spring water flowing directly from the source. Enjoy this private space at your leisure. Additionally, our creative cuisine, which blends Japanese and Western styles, is crafted using carefully selected ingredients from Kyushu, blessed with the bounty of the mountains and sea. We offer a delightful dining experience. Surrounded by trees and flowers that change with the seasons, and a star-filled night sky, immerse yourself in an extraordinary space that can only be experienced here, and spend a blissful moment.
This was my first stay here. The Room was beautifully designed and very comfortable. The open-air bath, a rock bath kept at the perfect temperature, felt wonderful at any time, and there was also a reclining bath where I could truly relax. The Japanese garden was also stunning and helped me forget the hustle and bustle of everyday life. The meals used plenty of local ingredients and were delicious. All staff provided very courteous service, and I would love to visit again. Thank you very much.
ゆる猫 7/28/2026From the moment we were welcomed through to the attentive care during meals, we received heartfelt hospitality throughout.We stayed in the Mizuki Room, and it was wonderful.The living area has a sunken kotatsu and felt a bit compact, but since there were only two of us, it was perfectly comfortable.There is a footbath area where you can sit on a rocking chair, and the open-air bath had hot water flowing continuously—perhaps free-flowing from the source. There is also a cold-water tap, so you can add water to adjust the temperature.We couldn’t find an Onsen analysis report.The footbath and open-air bath are set in a spacious, relaxing area; we could unwind on the deck, or soak while gazing at the rocks and sky, which felt very calming.There are two toilets; one was TOTO’s top-of-the-line model.Even the amenities reflected thoughtful hospitality, so guests may want to look forward to them.Nearby Tawarayama was also lovely!
