The Shibuya junction or crossing is famous for being the “world’s busiest pedestrian crossing”. It’s apparently a popular tourist attraction although I don’t completely understand why because I would not want to be caught in the middle of a busy intersection where every two minutes, the traffic lights change and “thousands of pedestrians all cross at the same time from five directions.
When the crowds meet in the middle chaos ensues.” Seem to me it would be easy to get hurt, but there are other reasons people like to visit, not the least of which is that it’s a great place to take photographs.
