Everyday about 2,000 metric tons of seafood passes through the market everyday.
At that time, Tokyo was known by its former name Edo.
As the city grew, so did Uogashi until it developed into a large-scale wholesale market.
In 2013, a 489-pound bluefin tuna was sold for a a mind-boggling $1.76 million.
The auction takes place in the inner market where only licensed wholesale dealers operate.
The auction begins at about 5:30 AM and ends at 10 AM.
For large fish like tuna, it is an elaborate process.
About 700,000 metric tons of seafood worth 5.9 billion US dollars are sold here every year.
The city plans to lay a road through this area as japan prepares Tokyo for the 2020 Olympics.
