I dare say / guess that 2 combined factors will have helped the successful evacuation effort (especially given that these aircraft for Japan internal flights are some of the densest passenger configurations): 1. Domestic flight, with people less likely to be hauling around lots of belongings, although in Japan people already bring much less onto flights with them. 2. The well-known social expectation/procedure-abiding inclination of everyday Japanese people kicking in to enforce an orderly (and no bag-carrying) exit. Others may have observed similarly when flying in Japan. They can regularly board a widebody plane in 15 minutes, whereas 30-40+ minutes for the US still produces departure delays. I am guessing this efficiency factors into the evacuation as well. Versus other evacuation videos I have seen where people are actually exiting with their rollaboards. Really shocking.
