Tsukiji - Tokyo fish market

Tsukiji was the largest wholesale fish and seafood market in the world.
The market opened on 11 February 1935 as a replacement for an older market destroyed in the 1923 Great Kanto earthquake, and closed on 6 October 2018 to move to the new Toyosu Market.
The tuna auction was the unmissable attraction of Tsukiji. The auction started at 5.30 a.m. and this means that you had to be in queue very very early (2.30 a.m. at least) given that only 120 visitors could witness the tuna auction on any given day.
