My friend Tom Galloway (who knows everything about everything) sent me this note about the video link just before this post…
FYI, the intersection they start off in, and return to a time or two, is Shibuya Crossing in Tokyo, considered the busiest pedestrian intersection/crossing in the world. To the point where it's actually a tourist attraction (although being in a major shopping area doesn't hurt). At peak times, there can be literally thousands of people crossing in it. I'm curious how much work/time it took for them to get filming permits for their video there. Possibly worth looking at a YouTube video or two that just shows it in normal everyday use.
I am sometimes amazed (and at times, annoyed) at how much most cities in the U.S. are willing to discomfort and inconvenience their citizens if some movie or TV company wants to stop traffic or block off streets to film a scene for just about anything. I guess it's the same in Japan.
