Nishin (Pacific herring) can be found in Northern Japan from Toyama and Ibaraki prefectures northward, the northern part of the Yellow Sea, in the Pacific Ocean from California northward and in the Arctic Ocean. The body grows to about 30 cm long.
This is a popular local topping in Hokkaido. It has gradually started gaining popularity outside of Hokkaido as well and you can find it in a wider variety of regions now. Notice the umami distinctly found in silver fish. It has a relatively refreshing taste for a shiny-skinned fish so it is easy to enjoy. As it loses its freshness rather quickly, it is often marinated in vinegar before preparing as sushi. It is a special treat when you find the raw version served fresh.
Also called California herring or Eastern herring or North pacific herring or Oriental herring or Herring.
