Tsukiji Fish market – Tokyo
Once upon a time, a visit to Tsukiji was strictly for travelers, freshly arrived in Japan, whose jet lag caused them to get up at 4 a.m., hours before anything else was open. Then the rest of the world discovered how delicious raw fish is, and everything changed. Be forewarned, though. Tsukiji remains first and foremost a working marketplace, so don’t stand in the aisles snapping pictures too long, or you’re liable to get run over by one of the dozens of service carts skittering about the complex.
