A hidden hot spring Property registered as a tangible cultural heritage, where you can enjoy natural hot spring water at your feet.

A secluded hot spring property located within Jōshin'etsu Kōgen National Park. Famous for its Rokumeikan-style grand bath "Hōshi no Yu," reminiscent of the Meiji era.

  • This Accommodation offers heartfelt hospitality throughout—and you even get to stay in a rare, registered cultural property building. As you step through the entrance, you’re welcomed by a traditional architectural space with a high-ceilinged hall and the gentle smolder of firewood in the irori hearth. The cuisine is prepared with great care, with no shortcuts. There are three Onsen baths, with fresh spring water welling up directly into them, and separate time slots for men and women so you can relax at your own pace. We chose a Plan without an in-room toilet or bath, but it was a wonderful Room filled with the soothing sound of the river. Thank you very much.

  • The Onsen and the Room atmosphere were excellent, and the service was great.After check-in, there isn’t much to do besides taking a walk around the Accommodation and the surrounding area, but we were able to slowly enjoy an extraordinary getaway with just the Onsen, the Room, and the meals.It’s an Onsen I’d definitely like to visit again.Next time, I plan to check in early and spend a luxurious time relaxing with a book.
