A hidden Hotel with the concept of “staying in a bar”

Featuring a unique fusion of a bar and a Hotel, your extraordinary experience begins the moment you check in at the bar counter during twilight. At "the bar," we offer a selection of light meals that perfectly complement the bar experience, alongside hundreds of whiskey bottles, original seasonal cocktails, and carefully curated fine spirits by our skilled bartenders. Our private bath comes with a bar counter and sofa, allowing you to relax and enjoy your drinks at your leisure. In the refreshing lounge surrounded by greenery, we serve a champagne brunch. Savor coffee or champagne while enjoying the breathtaking mountain views through the windows.

  • The bar counter was wonderful, and we enjoyed many cocktails. When we shared our preferences, the bartender created drinks on the spot, making it a truly enjoyable experience. The champagne brunch we had been looking forward to was a luxurious moment with breathtaking views. We were able to relax at the bar during café time and in the Onsen until the 2:00 PM check-out, making for a very satisfying stay. We would love to visit again.

  • I finally visited this long-awaited Hotel for the first time.I called on the day of arrival and requested Shuttle Service to Chokoku-no-Mori Station.Because the number of Rooms is limited, neither the dining areas nor the Onsen ever felt crowded, and I was able to relax at a very leisurely pace.The staff’s thoughtful hospitality was outstanding, making it a truly meaningful stay.The cocktail pairing at dinner was a wonderful experience, with cocktails I would not normally order myself.Brunch also offered a wide variety of options, and it was a delight to enjoy champagne and wine from the morning.I felt this Accommodation is easy to use even for solo travelers.Thank you very much for such a wonderful time.
