Found a video to share with you. Subway train comes very 1:30--2 minutes (smaller stations are 3-4 minutes) and they are almost 100% on time. I believe this video was not filmed at rush hour. At rush hour, the station can be very crowded but still in order in its own way. People are polite and follow the “rules” even when they are in a rush.
It’s a bit hard for non Japanese visitors to find out what are the “rules” from the beginning, but if you pay attention to what others are doing, you will learn quickly.
