The Tokyo Metropolitan Central Wholesale Market, commonly known as The Tsukiji fish market is located near the Tsukijishijō Station on the Toei Ōedo Line and Tsukiji Station on the Tokyo Metro Hibiya Line. There are two distinct sections of the market as a whole. The "inner market" (jonai shijo) is the licensed wholesale market, where the auctions and most of the processing of the fish take place, and where licensed wholesale dealers (approximately 900 of them) operate small stalls. The "outer market" (jogai shijo) is a mixture of wholesale and retail shops that sell Japanese kitchen tools, restaurant supplies, groceries, and seafood, and many restaurants, especially sushi restaurants. Most of the shops in the outer market close by the early afternoon, and in the inner market even earlier.
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.
