Japanese Horse Mackerel is a commonly found coastal fish in the waters surrounding Japan, as well as in the western Pacific Ocean. It has a streamlined body with a silver belly and a bluish-green back, characterized by a distinct lateral line with hard scutes (bony scales). Typically, it grows to about 20–40 cm in length.
This species is known for forming large schools and is often found in nearshore areas and bays. It primarily feeds on plankton and small fish. Economically, Japanese Horse Mackerel is an important species in both commercial and recreational fisheries.
Its flesh is light, tender, and flavorful, making it a popular choice in Japanese cuisine. Common preparations include grilling with salt (*shioyaki*), deep frying (*aji fry*), sashimi, or marinated dishes like *nanbanzuke*. Due to its affordability and availability, it is widely enjoyed in both restaurants and home cooking across Japan.
