Japanese Edo Ichiba: The Fish Market Culture of Tsukiji and Toyosu

Tokyo (Edo period markets to Tsukiji 1935–2018; Toyosu 2018–present)

The culture of the great fish market sits at the heart of Tokyo's culinary identity. Tsukiji, operating from 1935 until 2018, was the world's largest fish market by transaction volume—handling 480 categories of seafood from 60 countries daily at peak operation. Its replacement at Toyosu continues the tradition in a modernized enclosed facility, though the old outer market (Jogai Ichiba) at Tsukiji persists as a culinary destination. The market culture generated its own cuisine: the early morning tuna auction breakfast, teishoku sets of maguro don and miso soup eaten by market workers at 5am, the specific vocabulary of market grades (jō/chū/ge), the knife ceremonies of the maguro kaitai show. Professional buyers develop what traders call mekiki—the ability to judge quality through sight and touch alone, often achieved only after years of apprenticeship. The ike-jime and shinkeijime precision slaughter techniques (to immediately halt nervous activity and prevent rigor mortis from setting in) were refined and propagated through market fish handling culture. For restaurant professionals, understanding the auction system explains why premium tuna grades have relatively fixed price floors—bidding culture sets seasonal benchmarks that ripple through wholesale pricing for the rest of Japan.

The market itself has no flavour but gives flavour to everything: the first-grade tuna's clean ocean minerality, the rich fatty chutoro melt, and the market breakfast's simple clarity are all products of this institutional culture
