An illustrated book that explains the law in simple terms has sold over 500,000 copies in just over 6 months. Aimed at children, the author Soichiro Yamasaki hopes that understanding the law will help address the ongoing issue of bullying. Yamasaki is not a legal expert. Instead, he draws on his own experiences to drive home the point that bullying is a crime. He talks about how he hopes that the book will not only discourage kids from becoming bullies but also help kids protect themselves.
