Toyosu Tuna Auction Time

The tuna sold at Toyosu are frozen so hard that buyers shave the tail with a hooked blade and rub the flesh between their fingers to judge fat content, working by torchlight along rows of fish laid out like polished stone. That inspection is why the toyosu tuna auction time falls where it does: the bidding cannot start until the buyers have finished reading the fish, and the fish must reach Tokyo's restaurants before lunch service. Everything about the morning is shaped by that narrow corridor of hours. What a visitor is dealing with, in practice, is a working wholesale market rather than an attraction with a queue and a turnstile. Toyosu Market opened in October 2018 as the successor to the old Tsukiji inner market, and the fish trade moved wholesale into three buildings connected by bridges at 6-6-1 Toyosu, Koto-ku. Fish Intermediate Wholesale Market Building — usually signposted Building 7 — holds the observation windows above the auction floor. The upper glass gallery is open to anyone who turns up; the lower deck, the closer vantage where the handbell and the auctioneer's chant are audible, is limited and allocated by advance lottery. Neither costs anything to enter. The context that makes the schedule make sense is the supply chain behind it. Bluefin arrive overnight from Oma, Hokkaido and overseas longliners, are numbered, and are laid out for pre-dawn inspection. Once the bell rings the lots move fast, often in a matter of minutes per row, and the floor empties toward the intermediate wholesalers' stalls while the gallery is still filling. Many travellers pair the visit with breakfast at Tsukiji Outer Market, a fifteen-minute ride away, where the retail shops and knife sellers stayed put after the inner market relocated. What to do with the answer is straightforward. Treat the auction as a fixed appointment rather than a flexible sightseeing stop, and build the rest of the morning around it — the sushi counters at Uogashi Yokocho, the rooftop lawn above Building 6, the Tsukiji Hongan-ji temple later on. Anyone booking a guided Toyosu fish market tour should check that the itinerary reflects the same toyosu tuna auction time rather than a later, gentler start; the difference between 05:00 and 07:00 is the difference between watching a live auction and watching a cleaning crew hose down an empty floor.
