There is the famous episode that Japanese get in line to get the distribution of food,when the big earthquake was occurred and there are not water and food.
In the situation of such emergency, most people seems to think about only myself or family.
So riot and plunder are more likely to happen.
But there are no riot in Japan, when the big earthquake was occured in 2011.
The reason of this is the education of Japan.
Japanese children have edudation of “Doutoku” at elementary school.
“Doutoku” is the education to think about the style of people should be.
“Don’t hurt other people.”
“Think about not only myself but also other people.”
“Value other people kindness.”
and so on.
This mental education make kindly action of Japanese.
