  1. Shibuya is a valley. Several of the busiest lines coming in do so at the SECOND OR THIRD FLOOR. The B2 underground promenade serves the Fukutoshin/Toyoko Line and Hanzomon/Den-en-Toshi Lines. A lot of people coming in on those lines will follow signs to the most appropriate exit. People coming in on the 3rd floor aren't going to walk down to B2 to cross the street and then go back up 2 floors. When they get to ground level they're just going to exit. Keio, Ginza and in particular the Yamanote Lines all feed this, dumping people right next to the scramble. (Well, Ginza mostly dumps people farther east now, but by and large those people still funnel over to the crossing. A lot more of the train infrastructure for Shinjuku dumps people out at B1 so people use the underground promenades to get to a more appropriate exit.
