The Japanese horse mackerel (Trachurus japonicus) is a species named after mackerel in the family Carangidae.[1] Their maximum reported length is 50 cm (20 in) with a common length of 35 cm (14 in). They have a maximum reported weight of 0.66 kg (1.5 lb) and a maximum reported age of 12 years.[2] They are found around the coast of Japan, apart from Okinawa Island, usually on sandy bottoms of 50–275 m (164–902 ft) deep.[2] They feed mainly on small crustaceans such as copepods, and shrimps and small fish. They are similar to the yellowtail horse mackerel around New Zealand and Australia, apart from having more gill rakers and larger eyes.[3]

The Japanese name for this fish is Aji (あじ). It is most commonly written in hiragana. There is a kanji, but it is not in common use. It is commonly deep fried ("aji furai" あじフライ) or salt-grilled ("shioyaki aji" 塩焼きあじ).
