World's Most Crowded Street (Shibuya, Tokyo, Japan)

With 2.5 million people a day, there's no doubt Tokyo's Shibuya is the busiest intersection in the world. No matter what time you go, the crossing is always busy. During the day, in the middle of night, at dusk – the amount of people is always consistent. It must be quite exciting when the green light goes on and you see the thousands moving in your direction.
