One of my friends is from northern Japan, and he told me that when he was a HS student, his bullies threw him off a 3rd floor like that.
Luckily, it snows down a lot, so it broke his fall, and he was perfectly fine.

I live in Japan, and in the school I was we had around 4 cases of sexual assault, and even though they were reported to school, nothing happened.
Nothing ever gets resolved unless you have something like video prove.
