A serene adult Onsen resort in Izu with a lush Japanese garden.

  • We stayed in “Yamabuki 301” for a refreshing getaway as a couple. Although we arrived a little earlier than planned due to our own circumstances, the staff welcomed us warmly and graciously, which truly impressed us.What stood out most during our stay was the outstanding dining experience. The French dinner was delicate and beautifully presented—something to enjoy with all five senses—and we savored it to the fullest along with the wine pairing. Even after returning to our Room, we found ourselves talking together about the lingering impressions of the meal. The Japanese breakfast was also wonderful: rice, soup, and grilled fish were served at their best—perfectly warm and delicious—and we felt genuine hospitality in every detail. We would have loved it if items like the miso and nori tsukudani served at breakfast were available for purchase at the shop.One reason we chose this Room was its water garden, and it was truly soothing. In particular, the atmosphere of the in-room bath and its perfectly balanced water temperature were exceptional—it melted away all our everyday fatigue. The spa we enjoyed as a couple was also an excellent relaxation experience from start to finish, thanks to attentive service and skilled all-hand treatments. (It would be even better if there were options such as massage Plans focused on deep tissue or loosening tight muscles.)If there is one small point: since it was an extremely hot day when we visited, we wished the refrigerator in our Room cooled a bit more strongly. However, overall satisfaction far exceeded that minor concern—this was a truly wonderful Accommodation.Next time, we’d love to visit in another season to enjoy the changing scenery; in summer, perhaps choose a villa with a pool; and while the French cuisine goes without saying, we’d also like to try Japanese dinner during a Multiple Night Stay. We’re grateful to have found an Accommodation that makes us want to return again. Thank you very much.

  • A long-held wish came true, and I stayed with my pet at a villa I’d been curious about for some time. The open-air bath, water feature, and bed—everything made me feel truly pampered. The illuminated view at night was especially beautiful. The open-air bath in the Room was spacious, and I wanted to soak in it again and again. It was a wonderful Onsen, and I had a rich, relaxing time.For dinner, I enjoyed authentic French cuisine for the first time in a while. Great care was taken with the tableware and presentation, and every dish was thoughtfully prepared and delicious. The vegetables, eel, splendid alfonsino, and venison were all outstanding. For breakfast I chose Japanese cuisine; it was also carefully prepared and delicious, especially the dried horse mackerel.There was an issue with a Room Facility, but it was handled promptly, and the next day the general manager also greeted me. It truly felt like a luxurious stay overall. Since this is a pet-friendly Room it may be unavoidable, but I did notice some areas where cleaning could have been better. This may be an overly bold request, but it would be perfect if guests could bring their dogs to meals as well (for example on a cart). Because meal times are long, I worried about leaving my dog alone in the Room.Overall it was a luxurious and fulfilling stay. Thank you very much.
