22. Tsukiji Tuna Fish Market, Japan
The Tsukiji Tuna Fish Market is a bit of a rollercoaster in terms of visitation. It is a large fish market that holds an auction daily, filled with impressive fish, mostly tuna but also oftentimes exotic catches. Only those who have authorization are able to participate in the auction, but the entire process, the fish, and then the elaborate preparation afterward are all major draws for tourists.
However, due to overcrowding and other such problems as an earthquake at one point, the market has been closed to tourists on and off. There was so much of a problem the market was even moved to a new location. Nowadays, you can visit, but the amount of tourists allowed in is limited so best to get there early. Besides, there’s no telling when it will be closed off again.
