One manifestation of commendable discipline in Japan is through its escalator ettiquette. The Japanese usually divide their escalators into two sides: the right and the left. In Tokyo, people keep left and leave the right side open for rushing people, especially passengers for trains.
This is the reverse for Osaka wherein people usually keep right and leave the left side open instead. So if you have no idea which side of the escalator you should stand in, I recommend just following the person right in front of you. You do not want to be a big potato on one side of the escalator and block the way for rushing passengers, do you?
