Indulge in the "gastronomy" pursued in the rich land and the freshly born "Onsen" from the source.

2023 NEW OPEN! A three-room auberge Onsen Ryokan where you can enjoy freshly sourced Onsen with a focus on water quality and cuisine crafted by a Michelin-starred chef. All Rooms are over 135 square meters, featuring a maisonette style with two bedrooms and a private open-air Onsen bath made of cypress wood. Additionally, two Rooms are equipped with private saunas, offering a luxurious space for a carefree stay, akin to a private villa. The property includes a restaurant building, a private bath "Yumuro," and a fire pit, providing delightful experiences beyond the Rooms. The highlight is the dinner! At the live kitchen restaurant, the Michelin chef prepares a course meal right before your eyes, featuring seasonal local ingredients with creative presentations and exquisite flavors. From check-in to check-out, this Property offers an unforgettable experience that can only be found here.

  • I came to Yamagata for the first time because I wanted to stay here. Since it’s in the middle of town, I wasn’t sure what to expect—but once inside, it felt like a different world. It was quiet and relaxing, with a real sense of nature.The Room was wonderful—so spacious that it almost felt too big for two people—but we could truly unwind as if we were staying at a private villa. The Onsen water quality was also excellent and incredibly soothing.Above all, dinner was absolutely delicious and genuinely moving. Of course the chef’s skill is outstanding, but it also reminded me just how rich Yamagata’s food culture is. Because dinner is served at the counter in small numbers, it was great to hear directly from the chef, and it left a very positive impression to see how kind and close-knit the staff were. It was such an enjoyable dinner.I was a little surprised when the president came around to greet us. I also heard that at Takinami next door he makes soba every day for dinner—I’d love to try that someday as well. What a wonderful person.Although this is a luxury Accommodation, it also feels warm and welcoming—an extremely comfortable place to stay. I’d love to visit again in another season someday.

  • This is my third stay, and the Michelin-starred chef’s Italian cuisine surprises me every time with a different menu. It’s rare to find Italian food this outstanding even in Tokyo. Conversations with the staff are also enjoyable, making for a wonderful dinner time. Breakfast is equally exceptional, featuring local rice such as “Yumegokochi.” The Room is spacious, and Netflix is available without limits. The Onsen water quality is superb in both the private bath and the in-Room bath—an auberge with no flaws. I’m already looking forward to my next stay.
