This is so sad and tragic...such a young girl...

It's is not good to be bullied in school...it makes you feel so lonley...

Anyway, even in my country suicides at young age/13-18/ happen for similar or other reasons. Maybe the parents should have been more caring with their daughter, they should of have had stronger supervision on their little child. But typically for Japanese dads is to be working all day and have no time for their kids and her mother maybe wasn't aware of what would of have happen. Sadly the worst has happened.
Rest in peace little girl.
