“This soba kaiseki restaurant serves the produce of the mountain village, harvested from nearby mountains, fields, and rivers. The restaurant is housed in a relocated old house that took 12 years to build at the end of the Edo period, and serves exquisite local cuisine. The restaurant’s name comes from “”Harikoshi Manju,”” a local buckwheat dish that appears in Shimazaki Toson’s “”Chikuma River Sketches.”””
