It was the first time I went Tsukiji Fish Market in early June 2015. It's a large wholesale market for fish in central Tokyo. About 9AM on Saturday, really crowded when I was there. Things coming and going. I was trying to photograph working people and tourist as a street photographer. It was a really fun experience.
If you are planning to come here, you should hurry. The Tsukiji Fish Market is scheduled move to a new site in Toyosu in 2016. It's supposed to be clean and neat. I mean old and dirty is better for capturing documentary photograph.
