"The Tokyo Metropolitan Central Wholesale Market, commonly known as Tsukiji fish market (Japanese: 築地市場, Tsukiji shijō) is the biggest wholesale fish and seafood market in the world and also one of the largest wholesale food markets of any kind.Getting there: Don't go on Sunday when the market is closed. Take a taxi if you want to arrive really early. Otherwise, the Tsukiji station on the Hibiya subway line will get you within a 5-minute walk."
