Shibuya Crossing in Tokyo, Japan is the world's busiest crossing intersection. It's awfully amazing how you see the crowd of people crossing the intersection once the pedestrian light is GREEN! It's like people coming and going from all direction.
I was there the first time and felt like it reminded me of some zombie movies. So I kinda enjoyed it and crossed all the way back and forth for like three times. I took a video of it and hope you'll get some idea of how is it actually like.
Every crossing is crowded as much if you are wondering there'll be less people this time.
