The violent acts in Japanese schools

This chart that I found on the newspaper the other day shows the number of violent acts in the Japanese schools has been increasing sharply. (The black line shows the amounts. The light blue line=middle school,  the dark blue=high school, and the gray=elementary school) What’s going on in schools? Why are they so impetuous?
It reminds me of an incident happened several months ago.

Several months ago, Tatsu(my 9-year-old son) had a quarrel with one of his classmates. That boy  has a reputation for touching their teacher’s teaching materials supposed not to touch while their teacher is absent from the room. Tatsu , as you know, is a person who can’t ignore such a thing, so he started to point a finger at the boy. However, the boy disregarded Tatsu. Tatsu kept reprimanding him, and finally the boy said ” I’ll kill you!”. Tatsu answered him, “Do it! If you can!” and Tatsu ended up being hit and cried. Tatsu was so shocked and got upset. I guess he got upset about his provocative attitude that he didn’t necessarily want to have. He was disturbed by his careless word against that notorious boy.

Their warmhearted veteran teacher, who is around fifty years old, took both of them to another room and let them talk frankly about what they were thinking. According to her, Tatsu expressed to that boy how much he was disappointed and hurt very emotionally. She said his touching speech made the boy conscious of his actions. The boy started to cry as well!! After that, they made up.

That evening, I asked Tatsu how he felt about the boy. He said that he didn’t have any bad feeling towards him anymore, and he accepted the boy’s apology as sincere.  Before this incident, I had persuaded Tatsu not to be involved with, or not to nag at those misfit types and just ignore them. Because I’m afraid of him getting bullied. Tatsu can speak his mind very clearly and logically. It’s nice during the peaceful moment, but you know, he speaks his mind too much sometimes. However, I reflected at this time that I had discriminated against these misfit kids unconsciously, and tried forcing Tatsu to think  the same way.

I take these increasing numbers of violent acts as indicating the number of ignored kids.  People ignor the misfit kids because they don’t understand their minds. Uh..I’ve said a commonplace thing..but they are ignored by adults, teachers and peers. So, I guess that’s  the reason why they are so busy in texting each other.  Nevertheless,  I got used to seeing kids, even girls, chattering in the park at MID NIGHT, or eating HOT INSTANT NOODLES IN THE TRAIN and LEAVING the bowl there. Am I supposed to chastise them in public? I don’t think so. It’s up to their parents, I believe.  

Why are their parents  so dull???  How come can they abandon their responsibility as parents??  They really don’t know what their kids are doing outside the home??
