Mountain Foraging at Dewaya Inn

Surviving off the gifts of the mountain.

Experience Outline

At Dewaya, an inn specializing in local sansai (mountain vegetables) cuisine, find physical and spiritual nourishment from the mountain itself.

Experience Details

Sansai, meaning mountain vegetables, is an umbrella term covering a diversity of wild plants, leaves, and vegetables. Deep in the Dewa Sanzan area of Yamagata, in the remote village of Nishikawa, a traditional homestead called Dewaya maintains the skills and traditions of foraging, preserving, preparing, and dining based on these wild plants. Learn the wonder of the mountain, the treasure box, and you’ll see why the chefs call it their natural pantry.

Accompanied by an interpreter, this is a unique opportunity to join Haruki-san, the third generation master and chef of Dewaya inn, to encounter wild food and centuries-old culinary traditions, where farming meets foraging. Venture into mountain trails to forage for sansai, mushrooms, and beech nuts, visit a natural spring water source, and walk through the birch tree glade to spot green silkworm cocoons and seek wild berries.

Back in Dewaya, get a special look inside the pantry of this multi-generational homested, where preserved sansai of generations past are still used, including some which can no longer be found in the wild. Your gathered ingredients will be used in a personal cooking demonstration lunch, accompanied by local sake crafted from the mountain’s spring water.
