Osaka School Massacre - Aftermath

Aftermath

Takuma was diagnosed with Borderline personality disorder, Antisocial personality disorder, and Paranoid personality disorder. He was later convicted and sentenced to death by hanging. The sentence was carried out on September 14, 2004. The Osaka School Massacre was the second largest mass murder, along with the Matsumoto incident, in recent Japanese history, exceeded both of the crimes only by the fatalities caused in the Sarin gas attack on the Tokyo subway. This incident, however, was set apart by the young age of the victims, by its occurrence at a school, and by the murderer's history of mental illness. Because of these factors, the Osaka School Massacre raised questions in Japan about the country's social policies regarding the treatment of mental illness, the rights of criminals and victims, and the accessibility and security of Japanese schools.

After the attack, Yoshio Yamane, the principal administrator of the school, announced that it would receive a security guard, an at-the-time unheard-of feature in Japanese schools. Additionally, J-Pop artist Hikaru Utada rearranged her song Distance in honor of Rena Yamashita, one of the murdered schoolgirls (because of an essay contest she had won, talking about how she respected and wanted to become like Hikaru), retitling it Final Distance. Exactly seven years later, a similar stabbing massacre called the Akihabara massacre took place, though not in a school but in the streets of Tokyo.
