Even after the wholesale market moved to Toyosu, this warren of tightly packed stalls retains its old-Tokyo energy and remains a pilgrimage site for anyone who takes food seriously. You'll zigzag between vendors hawking freshly shucked oysters, sunshine-yellow tamago-yaki on sticks, and deep-fried fish cakes still crackling from the oil. Professional chefs who've shopped here for generations rub elbows with tourists hunting the perfect knife at Tsukiji Hitachiya. Come early, come hungry, and prepare for the best breakfast of your life.
