You’ve seen this. It’s that crazy four-way intersection that people all cross at one time. Shibuya is a little like Times Square—not a place to spend a ton of time in, but everyone should see it at least once. Said to be the busiest intersection in the world, as many as 1,000 people will cross at the same time. For an aerial view, go to the second floor of the Shibuya train station, find the Myth of Tomorrow mural, and look out at the intersection from there. Best time to go: evening, when Shibuya’s neon is at full blast.
