Standing on the escalator at Shin Tokorozawa Station.
Here in the kanto area, everyone stands on the left and climbs the escalator on the right. This is the opposite in the kansai area. In more regional towns, they just sort of stand. Now that I think about it, that's probably how we're suppose to ride it.
Anyways, I usually climb the escalator because I'm not patient enough to wait. Plus you get the teeniest bit of exercise.
