Nishin Soba (にしんそば, Nishin Soba) is a classic Japanese noodle dish featuring buckwheat soba noodles served in a fragrant dashi broth and topped with sweet-simmered Pacific herring (migaki nishin). Originating in Kyoto, this comforting dish has been enjoyed since the late 19th century and is celebrated for its delicate balance of savory broth, earthy soba noodles, and tender, flavorful fish. The herring is slowly simmered in soy sauce, sugar, mirin, and sake until it becomes soft enough to melt in your mouth.

Nishin Soba remains one of Kyoto's signature noodle dishes and is especially popular during the cooler months.

What is Nishin Soba?

Nishin Soba combines hot soba noodles with kanro-ni, a traditional Japanese preparation in which dried or fresh herring is gently simmered in a sweet-savory sauce. The rich, slightly sweet fish pairs beautifully with the light umami of the dashi broth.

Typical garnishes include:

  • Green onions
  • Shichimi Togarashi (Japanese seven-spice blend)
  • Yuzu zest
  • Kamaboko (optional)

The dish is simple yet deeply satisfying, highlighting the refined flavors of Kyoto cuisine.
