Not to downplay the severity of the problem in America, but bullying is pretty damn severe in East Asia. The "nail that sticks up gets hammered down" quote often used to describe the situation there. Search "japan bullying" in Youtube and you'll find a long list of videos talking about the issue in Japan in particular.

I know it's not exactly a reliable record, but Japanese high school anime are a popular genre and pretty consistently depict a fairly intense atmosphere of bullying. It's often not the focus so you have to read between the lines a bit in some of them, but it's usually there. Not sure how much of that's true and how much is fictional trope.

I'm not sure what you mean by Japanese high school anime? Some anime, particularly in the slice of life genre, depict a idealized version of high school where there is no bullying.
