Aji Horse Mackerel Tataki Himono Preparations

Japan — aji consumed since prehistoric coastal settlements; tataki and namero documented in Edo period fishermen's cuisine

Aji (鯵, horse mackerel, Trachurus japonicus) is Japan's most commonly eaten blue fish — abundant, affordable, and deeply embedded in everyday Japanese cooking. The standard preparations reveal the fish's versatility: nanbanzuke (marinated in vinegar with chili after frying); aji no tataki (finely minced with miso, ginger, negi — served raw or seared); himono (half-dried, grilled — the most popular breakfast fish in Japan); aji furai (breaded and fried); and aji no namero (Chiba's specific minced-miso preparation eaten by fishermen). The small silver spine (zeni) must be removed before most preparations. Sagami Bay and the coast around Kanagawa Prefecture produce the most prized aji.

Clean, lively blue fish acidity — aji's slight oiliness and fresh ocean character is Japan's most accessible seafood taste
