i wouldn't know about japanese culture since i'm chinese american, but that kind of dynamic in primary school doesn't work. some kids don't understand that people have their own circumstances or have no filter/consistent morals whatsoever when they're working with other people (not that this applies to every child ever)
@hobisflower
from what i gather about japanese culture, though, is that people have a
tendency to conform and act as a group and drive out what is different, which is derived from Confucianism. (topic: japanese confucianism).
