Pacific sauryis a widely distributed fish species in the Northwest Pacific, commonly found in the waters off Japan, the Korean Peninsula, the East China Sea, and the Yellow Sea. The fish has a slender body, typically ranging from 30 to 40 cm in length, with a maximum size of up to 50 cm. Its back is blue-green, while its belly is silver-white, with distinct silver bands along its sides, making it easily recognizable.

Pacific saury is a migratory species, primarily inhabiting warm nearshore waters. They are known for their large migrations during the autumn, becoming an essential food resource in the ocean. These fish are carnivorous, feeding on small fish, crustaceans, and plankton.

The flesh of Pacific saury is delicate and rich in flavor, with moderate fat content. Its taste is especially prized in the autumn when its meat is the most plump and flavorful, earning it the title of "the taste of autumn." In Japanese cuisine, Pacific saury is a highly popular ingredient, often used for salt-grilling, grilling, or sushi. During the autumn season, the aroma and rich oil content of grilled saury are key components in home and restaurant menus. Additionally, its bones are commonly used to make broth, extracting its delicious flavor.
