The Shibuya Scramble Crossing is the defining image of contemporary Tokyo — an intersection where several hundred pedestrians cross simultaneously from every direction, every two minutes, in a choreography that should be chaos and somehow is not. On busy evenings, the numbers are staggering and the effect — seen from above — resembles a time-lapse of cells dividing.
Cross it yourself at least once; then watch from above. The best vantage point is the second-floor Starbucks in the Shibuya Tsutaya/QFront building, which has windows directly facing the crossing. Alternatively, the new Shibuya Sky observation deck on the Scramble Square tower offers a panoramic view with the crossing visible below.
