Shibuya crossing might be one of the most iconic images of Tokyo. From the onset, one might think it's just a simple intersection, but upon waiting for the red light, things become all the more clear. Traffic stops from all directions, turning the street into a pedestrian, all-way crossing. Suddenly a surge of people starts flowing from each direction, like fish swimming upstream and down. They call this the "scramble". Shoppers, students, couples, tourists and commuters all rush in all directions.
