This is one of the largest fish markets in the world. 1/6th of all the fish sold in the world comes through this fish market. At 5:00 a.m. each morning the fish is brought in to an auction. The large tuna pictured sells for as much as $10,000 each. I have never seen so many different kinds of fish and eels. Many of the fish are kept alive in tanks. You don't want to eat sushi on Wednesdays because the market is closed so you may eat day old fish on Wednesdays.
