WWII U.S. War Department Technical Manual

In the Japanese social system, individualism has no place. Children are taught that, as members of the family, they must obey their parents implicitly and, forgetting their own selfish desires, help each and every one of the family at all times. This system of obedience and loyalty is extended to the community and Japanese life as a whole; it permeates upward from the family unit through neighborhood associations, schools, factories, and other larger organizations, till finally the whole Japanese nation is imbued with the spirit of self-sacrifice, obedience, and loyalty to the Emperor himself.
