Tsukiji fish market (築地市場) 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, and is a major attraction for foreign visitors. The market handles more than 400 different types of seafood from tiny sardines to 300kg tuna, from cheap seaweed to the most expensive caviar. 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 5.5 billion US dollars). Tsukiji alone handles over 2000 metric tons of seafood per day. The number of registered employees varies from 60,000 to 65,000, including wholesalers, accountants, auctioneers, company officials, and distributors. The market opens at 3:00 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 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 starts at 5:30. The auctions usually end around 7:00 a.m. Afterwards, 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 located inside of 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 (some well over a meter in length). The market is most busy between 5:30 and 8:00 a.m., and the activity declines significantly afterwards. Many shops start to close around 11:00, and the market closes for cleaning around 13:00 - wikipedia.
