If you can cross the Shibuya scramble intersection without bumping into anyone, you are a member of the disciplined Japanese society, lol. I've seen the documentary of this traditional mass game performance of Sport Science University almost 10 years ago, and surprised they're walking more than 1000km in total as practice. It seemed the training was super hard as military boot camp. The scene of them crying and hugging each other after the performance was really touching.
