The vibrant Tsukiji market in Tokyo is always a hyperventilating experience for a photographer. I am also grateful to the city- and market authorities to let the ordinary public come and stroll there. they could have easily closed it to strangers for security reasons (all this knives and speeding self-propelled carts).
Knives and Blood in Tsukiji
The only thing is that you better awake early, as the peak activity at Tsukiji is in the wee hours of the morning. Arm yourself with determination and don't bring your best shoes, you might come back with bloody stains. The market is buzzing with hundreds of buyers, sellers, workers who slice and package tons of raw fish.
Tsukiji is THE fish market of the world. The Japanese being experts in fish quality because of their age-old fish diet, you will find the best quality here, even for frozen fish, I guess.
