Savor the blessings from the mountains at our Chef's Table, available for one group per day.

A culinary inn with a 95-year history, originally established as a lodging for pilgrims visiting the Dewa Sanzan mountains: Mt. Gassan, Mt. Haguro, and Mt. Yudono. Since 2020, the fourth generation ha...s started a chef's table offering special courses focused on "mountain ingredients." From spring to summer, enjoy fresh wild herbs, mountain vegetables, and river fish; in autumn, savor mushrooms; and in winter, indulge in game such as wild duck and bear. Food enthusiasts from all over the country gather to experience the seasonal bounty of the mountains. In spring 2023, the chef's table was newly renovated, now featuring only 8 seats.

Our environmental and social efforts

Our sustainability efforts

We regularly enter the mountains to maintain their ecosystem by walking around and responsibly foraging for wild vegetables and mushrooms. Sometimes, as part of our food education program, we take local children with us, ensuring that we do not bring anything that could become trash. At times, it feels as if the trees are communicating with each other, and I feel like a part of the great natural cycle that connects the mountains to rivers and then to the sea.

The information provided by the restaurant is shown. For details or questions, please contact the restaurant.

ChefHaruki Sato - The Fourth Generation Inheritor of a Mountain Vegetable Cuisine Inn

Born in Nishikawa Town, Yamagata Prefecture in 1988. Moved to Tokyo for university studies, where I learned about management and tourism, while starting my training at a traditional Japanese inn in Tokyo in 2008. In 2012, I returned to my family business, "Dewaya," to pursue a career as a chef. With the motto "Bringing the mountains to the world," I deepened my appreciation for local ingredients. Currently, I am the fourth generation of "Sansai Ryori Dewaya," running the inn alongside the young proprietress.

Food "A Supreme Dish Infused with the Wish to Bring the Mountains' Bounty to the World"

Under the belief that "the local food cooked by local people is the most delicious," we primarily use natural ingredients harvested in Tsukiyama and within Nishikawa Town, as well as other locally sourced ingredients from the prefecture. The "mountain produce," which is nurtured with plenty of water from Mount Gassan, is served fresh depending on the season, and thanks to the wisdom of local people, it is also preserved as salted or dried food. It offers a unique dining experience that makes you want to express gratitude to nature.

SpaceRenovated Chef's Table in Banquet Hall Space

The Chef's Table, which utilized the second floor of the warehouse, garnered significant attention from food enthusiasts nationwide. In January 2023, the banquet space within the facility was renovated. A spacious dining area and wine cellar were newly established, centered around a zelkova counter that was said to be buried wood from 2000 years ago. Reservations are limited to one group per day, with only eight seats available (for overnight guests, a minimum of two people is required, while day visitors must have at least four people to utilize the space).
