It’s not because Japan is a high trust society. It’s not enough to just trust everyone around. It’s a low individualism society - from a young age, children are taught the world is not about you. You must be quiet, courteous, obedient, and respectful. Standing out is actively discouraged. Voicing opinions is discouraged. When everyone understands they are not Gods gift to the country, they all behave better. Americans will never be like this. Our teachings to our children are exactly the opposite. Everyone’s opinion must be validated and respected even when it’s garbage, and children are taught they basically can walk on water.
