I don't know whether the concept applies in Japan, but right now everyone is walking like it's Monday morning. ;-)
Thanks! I rather enjoyed that, for a couple of minutes. I'll return to have another look when things are hopping.
Haven't read the OP, yet. So, I don't know how much of a voyeur this makes me. I do enjoy having unfiltered looks are places around the world; gets me out of my own little corner of perspective and thought, a bit.

P.S. In the process of reading the OP, now.
One of the best integrations of "flow of traffic" -- almost as a Leitmotif -- into film, that I recall, is in Ang Lee's earlier film (before "Crouching Tiger" and all that), "Eat Drink Man Woman". Set in then contemporary, early 90's Taipai. The flow of life -- which was also a central theme of the movie.
(And the soundtrack complemented and clarified those scenes, perfectly.)
Many Asian arthouse films are of the spice of life variety (not many Chinese/Taiwanese films anymore, but definitely many Japanese ones). If you ever have time to kill on a transpacific flight, the Japanese section of the entertainment system is always lots of fun.
