I agree the situation and circumstances differ in all countries, what is true for Indonesia, as you said where young children getting accompanied by their parents when going to and returning from school it's true to great extent in India too but in advanced countries to make their children independent they leave them on their own to take their decision after a certain age . Yes, that's true, the matter might differ based on public safety and infrastructure support.
You prefer the family culture of Japan but as a resident of Australia, I love their way . You have a great analysis of the situation, all the best.
