The Tsukiji Market, supervised by the Tokyo Metropolitan Central Wholesale Market of the Tokyo Metropolitan Bureau of Industrial and Labor Affairs, was the largest wholesale fish and seafood market in the world. It was also one of the largest wholesale supermarkets of any kind. The market opened on 11 February 1935 as a replacement for an older market that was destroyed in the 1923 Great Kantō earthquake. It was closed on 6 October 2018, with operations moving to the new Toyosu Market.
The market was located in Tsukiji in central Tokyo between the Sumida River and the upmarket Ginza shopping district. When the inner wholesale market was operational, it offered only restricted access to visitors. While the inner wholesale market has closed, the outer retail market, restaurants, and associated restaurant supply stores remain operational, and the area is still a major tourist attraction for both domestic and overseas visitors.
