The Tsukiji Market (築地市場 Tsukiji shijō), supervised by the Tokyo Metropolitan Central Wholesale Market (東京都中央卸売市場 Tōkyō-to Chūō Oroshiuri Shijō) of the Tokyo Metropolitan Bureau of Industrial and Labor Affairs, is the biggest wholesale fish and seafood market in the world and also one of the largest wholesale food markets of any kind. The market is located in Tsukiji in central Tokyo, between the Sumida River and the upmarket Ginza shopping district. While the inner wholesale market has restricted access to visitors, the outer retail market, restaurants and associated restaurant supply stores remain a major tourist attraction for both domestic and overseas visitors. The market handles more than 400 different types of seafood from cheap seaweed to the most expensive caviar, and from tiny sardines to 300 kg tuna and controversial whale species. Overall, more than 700,000 metric tons of seafood are handled every year at the three seafood markets in Tokyo, with a total value in excess of 600 billion yen (approximately 5.9 billion US dollars on November 24, 2013). The number of registered employees as of 25 January 2010 varies from 60,000 to 65,000, including wholesalers, accountants, auctioneers, company officials, and distributors. The market opens most mornings (except Sundays, holidays and some Wednesdays) at 3:00 a.m. with the arrival of the products by ship, truck and plane from all over the world. Particularly impressive is the unloading of tons of frozen tuna. The auction houses (wholesalers known in Japanese as oroshi gyōsha) then estimate the value and prepare the incoming products for the auctions. The buyers (licensed to participate in the auctions) also inspect the fish to estimate which fish they would like to bid for and at which price. The auctions start around 5:20 a.m. Bidding can only be done by licensed participants. These bidders include intermediate wholesalers (nakaoroshi gyōsha) who operate stalls in the marketplace and other licensed buyers who are agents for restaurants, food processing companies, and large retailers. The auctions usually end around 10:00 a.m. Afterward, the purchased fish is either loaded onto trucks to be shipped to the next destination or on small carts and moved to the many shops inside the market. There the shop owners cut and prepare the products for retail. In case of large fish, for example tuna and swordfish, cutting and preparation is elaborate. Frozen tuna and swordfish are often cut with large band saws, and fresh tuna is carved with extremely long knives. The Tsukiji fish market occupies valuable real estate close to the center of the city. Former Tokyo Governor Shintaro Ishihara repeatedly called for moving the market to Toyosu, Koto. The long-anticipated move to the new market will take place in November 2016, in preparation for the 2020 Tokyo Summer Olympics.
