The world’s most famous marketplace for maritime delicacies takes up an entire district of central Tokyo and gives work to 60,000 people. Every day, 2,500 tons of seafood pass through the Tsukiji fish market: exotic delicacies, edible seaweed, and every conceivable type of fish – all for sale. The most famous part of proceedings, though, is the daily tuna auction; at one point, it was drawing so many tourists that spectator numbers are now limited to 120, so you’ll need to be there by 2 a.m. if you want a ticket (the market doesn’t open until somewhat later). In autumn 2018, Tsukiji is scheduled to switch to a new location after over 80 years on its current site.
