A cozy space with the charm of Japan’s Taisho era.

Built in the Taisho era as a villa for the Mitsui zaibatsu, Mitsui Suishoen. This nationally registered Tangible Cultural Property has been revived as “Ryotei Momiji,” and is surrounded by seasonal gardens. We also offer comfortable guest rooms suited to modern needs while preserving a timeless atmosphere. Enjoy a soothing stay embraced by mountain tranquility and the vibrant presence of trees and flowers.

  • I had always thought that if I were to stay in Hakone, it would be at Suishoen, and my wish finally came true—I was able to visit at last!It was exactly the Accommodation I had imagined, and I could truly feel the high quality in every aspect, making for a very fulfilling stay.I was especially looking forward to the meals—not only were they delicious, but they were also a feast for the eyes. Both dinner and breakfast were wonderful. That said, the corn rice at dinner felt a bit overdone; I think simple corn would have been enough.The Room was more spacious than I expected and very relaxing, and I thoroughly enjoyed the bath with a footbath feature.Above all, the staff’s thoughtful hospitality was outstanding—this was an Accommodation where I felt truly comfortable.

  • This was my first stay at Suishoen, and it was truly wonderful.For dinner, we happened to be offered an open slot, so they kindly changed our meal from kaiseki to teppanyaki. We chose teppanyaki, and it turned out to be absolutely the right decision.Watching the chef cook right in front of us was entertaining in itself, and each dish was carefully prepared—everything was genuinely delicious. Not only the meat, but also the seafood and vegetables were excellent, and we enjoyed every course without getting tired of it. The pacing of the meal was perfect, and the portions were just right—not too much or too little—so we could enjoy everything through to the end.Breakfast was also very luxurious with a great variety of dishes. Being able to enjoy such a substantial breakfast in the morning felt special, and it was a completely different kind of indulgent time compared with our usual mornings. Not only dinner but breakfast left a strong impression as well.The best part for me personally was the private Onsen in our Room. I could soak whenever I wanted and relax without worrying about anyone else, so I ended up using it many times. Having an Onsen in your Room really is unbeatable.The Ryokan had a calm atmosphere overall, and we were able to take things slowly throughout our stay. The staff were polite and attentive, responding pleasantly to everything we asked for. It’s an Accommodation I’d want to stay at again if I come back to Hakone.The only small issue was that my wife didn’t find the hair iron among the amenities suitable for her. That part was slightly disappointing, but aside from that we were very satisfied.Overall satisfaction was high across the food, Onsen, Room quality, and service—highly recommended if you want a luxurious place to unwind at a relaxed pace.We will definitely stay again.
