Tsukiji is located on the banks of the Sumida river, close to the upmarket shopping district of Ginza.
The inner wholesale market handles more than 400 different types of fish and seafood.
The daily tuna auction is the world's largest.
As well as fresh, the market also auctions frozen tuna.
The chiming of the bell marks the opening of the auction.
The auction is over in little more than twenty minutes.
Some of the tuna from the morning's auction is taken directly to wholesalers in the market who waste no time in cutting the fish, ready for transportation to Tokyo's sushi restaurants.
Other smaller scale auctions also take place each morning, including the sale of uni (sea urchin).
A number of tiny sushi restaurants operate on the edges of the market, selling the freshest sushi breakfasts.
As the sun rises, the day's business at the market comes to an end.
