In Japan, seafood is a matter of national identity. Fitting then, that the planet's largest wholesale fish and seafood market, Tsukiji, sits at right at the heart of Tokyo. Sprawling across an immense site in Chūō ward, the market feels as much a sacred site as it does a hotbed of consumption and commerce. Doubtless Tsukiji has very real cultural and economic significance. But with dire current trends in marine biodiversity and fisheries and Tsukiji processing around 700,000 metric tonnes of marine life annually, it stands as a model for a bleak global picture.
