The Japanese whiting, Sillago japonica, (also known as the Japanese sillago or Shiro-gisu) is a common species of coastal marine fish belonging to the smelt-whiting family, Sillaginidae. As suggested by its name, the Japanese whiting was first recorded from Japan in 1843, but has subsequently been found to extend to Korea, China and Taiwan. The species inhabits a variety of shallow water habitats where it preys on a variety of crustaceans as well as polychaetes, bivalves and small fish.
