Tokyo's Tsukiji fish market is the largest in the world, with $15.5 million worth of fish sold there on a daily basis.
But the iconic market is about to get even bigger. Tokyo recently announced plans for a new fish market 40 percent larger than Tsukiji, to replace the 78-year-old landmark that's become cramped and run-down in recent years.
The city will shutter Tsukiji by the end of 2013, and the fish market will reopen in a new building 1.4 miles away by the beginning of 2014.
Business Insider's Jay Yarow got to visit the market on a trip to Japan last year. It was buzzing with activity when he arrived at 4:30 AM. Tourists aren't normally allowed into the market before 9 AM, because they get in the way of the men who are actually selling fish. But he snuck in and snapped photos until he was kicked out.
