Speculate Japanese social issue@Furusato

Furusato means "Hometown" in Japanese. For dinner tonight, my student Cyrille who is french and learning Japanese for a year with me invited me Furusato.
Whenever I go to Furusato I feel"home" and enjoy food and talking.
We had good conversation about Japanese culture like " hikikomori（nowhere kid）"　”Business man sarrow、get transferred separated from the family, working late, hierarchy　" etc.
He asked me that "I read French woman who lives Japan blog, is it true if your kids draw animals..let's say giraffe and colered blue, teacher said "no giraffe is not blue, has to be yellow! then, if kid does not listen the teacher, in the end teacher apologized parents?"
--- yes, I think it's true. I am not sure school education systems now but at least when I was school, I always felt presserd that make sure I do "the same things" with others.
Japanese education , culture is still a lot of pressher "have to be the same with others"
Originally Japanese learning style is in the Confucian ethic. It is 2500years old ethic but I think Japanese learning style developed based on Confucian ethic.
Invisible Japanese culture, I think many people have presser that have to be a" standard"and ”not haveing a strong individuality" under the pressure from the society, education system, family expectation..
21st century after bubble economics, I wonder, these traditional Japanese structure and modern culture, internationalization creats social issues. Many people are torn or confused between modern and traditional culture and customs?
Should not forget how Japanese economics is growing so fast after WWⅡ, because Japanese people are fold and good at manugfactuaring and　group organization　work.
*I have little basis, this is just my speculate.
