I was in a central part of Tokyo while working out of Google's Tokyo office for a few days, and didn't experience any crush passenger loads in the morning. In fact, the trains had plenty of space.
But I did experience a very, very packed train once while I was there, taking a commuter express line out of the city...at 9pm.
