My friend married a Japanese wife. Her parents are of Korean ancestry, living in Japan. She was born and raised in Japan, yet still has to register as a foreigner living in Japan. She has interesting and derisive observations of the native people there.
From young, the students are taught exactly how to behave and become a good Japanese citizen. Individuality is not tolerated. Left-handed students are forced to use their right hand. The saying goes: “The nail that sticks up gets hammered flat!” People would stare rudely at me as I ate left-handed with chop sticks.
I was a guest of a large Japanese electronics company that I was a customer of, on two separate occasions with two tours of the country. I spoke with one company engineer who was American educated and he noted how difficult it was to be a creative engineer when that attitude runs counter to the culture there. Independent thought is not encouraged.
