Seasonal cuisine and a relaxing Onsen with views of the sacred mountain.
Located within the Muikamachi Ski Resort, our facility is available year-round for activities such as skiing and trekking. The Onsen large public bath is highly popular, offering views of the sacred Mount Hakkai on clear days. The hot spring features sodium chloride water, which warms you to the core and provides a relaxing experience for both body and mind. Enjoy the charming open-air bath during sunset. For dining, we offer a variety of Japanese, Western, and Chinese fusion dishes made with seasonal local ingredients. In the green season, enjoy views of Minamiuonuma's mountains; in the snow season, immerse yourself in a world of white landscapes. Our bright dining venue provides a casual atmosphere where you can relax and enjoy your meal. The facility also includes amenities such as a library, gift shop, kids' room, and coin laundry for your convenience.
This was my third stay.Last time I stayed in a Deluxe Room, but this time I tried a Superior Room.The Room was smaller, but it was very easy to use, with convenient space for luggage and a well-placed heating setup.The bath and toilet were separate, and there was also a separate vanity sink, so even though we stayed as a large group, we were able to spend our time comfortably.Also, the desk, chairs, and mirror were arranged so that three people could sit side by side. Since there were many women doing their makeup, it really helped.And the food was amazing.Dinner had a time limit, but we could fully enjoy delicious dishes to our heart’s content. Breakfast was also so great that I ended up eating more than usual—the menu was wonderful and something I wanted to brag about to everyone.I didn’t take any photos so there are no images, but the meals are truly something this Hotel can be proud of.
Yahoo!トラベルユー... 3/24/2026The Room had been renovated and was very clean and easy to use. The mountain range view from the window was wonderful and truly relaxing. The meals were delicious, with just the right number of dishes. Even though it was a buffet, the area around the plates was always kept clean, and the side plates were lovely ceramic pieces. The spoons were sparkling clean. Both the ski rental staff and the ski lift staff were very pleasant, and I’d like to come again in summer as well.
