Fifteen years after her only child, Kasumi, killed herself at age 15, Midori Komori still hasn't received any apologies from the people who bullied her daughter and the high school she attended said no such abuse occurred.

When a child commits suicide as a result of being bullied, what the family desperately wants to know is the truth about what happened. They also want a sincere apology from the perpetrators, Komori said.

But this is usually just wishful thinking because schools and boards of education often refuse to disclose any information to the victims' families, she said.
