Get up at the crack of dawn-as early as 4:00 AM if you need time to prepare. Five AM is acceptable if you don`t have far to travel. It may suit you better to stay up all night, rather than to try and get up after only a few hours of sleep.
Take the subway to Tsukijishijo Station, on the Subway Oedo Line. Be forewarned that the first train may not run until a little after 5am, so check your local train schedules beforehand.
Disembark at Tsukijishijo Station, and follow the steady stream of tourists around the corner into a bustling fish market.
