What the absolute fuck are you talking about.
On this subject more than any other the western brain is completely destroyed by propaganda.
The crazy shit you will and have believed about Korea without any evidence is stunning and can only be explained by racism.
You actually believed when they said the whole country had to get the same haircut?
Some school districts in Japan already do this to kids tbh. There was a kerfuffle a while back and some schools dropped some limitations after lawsuits. Like if your kid has naturally curly or blonde hair you’d need to prove it. (Haven’t gone deep on fact checking, take it with a grain of salt)
I’d say it’s not unreasonable that if you have a manufactured preconceived (racist) notion about a place that you would believe it.
