Founded in 1789, this is the original Horii family soba shop, reopened in Azabu-Juban in 1984 after the historic Nagasaka Sarashina store closed decades earlier. The counter-and-tatami dining room has a traditional Edo-era craftsman atmosphere, with the noodle-making area visible near the entrance. The house specialty is sarashina-soba, a pale white noodle milled only from the innermost part of the buckwheat kernel, alongside hearty inaka-style futo-uchi soba and seasonal kawari-soba flavored with citron, mugwort, or other seasonal ingredients. A multi-course kaiseki menu is available on weekends and holidays by advance reservation.
