The culinary concept is "Oku-Yamanashi Cuisine" "Oku-Yamanashi" derives from the deep, secluded location of Saiko, where Restaurant SAI 燊 is situated—a hidden gem among the Fuji Five Lakes. This concept celebrates the unique ingredients available only in this rare and extraordinary location, elevating them into a culinary art form. It is designed for diners seeking an ever-evolving gastronomic experience. The foundation of the cuisine is wood-fired cooking, harnessing the power of various flame intensities to bring out the profound flavors of ingredients from the northern base of Mt. Fuji. These include game meats, mushrooms, mountain vegetables, highland produce, and freshwater fish. Breaking away from conventional norms, this new gastronomy is guided by the philosophy of "honoring all living things by consuming them fully." It is a bold and innovative approach to dining that showcases the deep connection between nature and cuisine.
