"This week, I'm going to blow up Nintendo headquarters." This anonymous online message appeared on September 10 of this year. Japanese police moved quickly to find out who was responsible for the threat—as well as other threats to blow up Ise Grand Shrine, one of Japan's most important Shinto shrines.
The police in Mie Prefecture located the computer where the threats apparently came from and brought the 27 year-old man who owned it into police custody. A week later he was released. The man, it seems, was apparently the victim of a computer virus. And it seems he was not the virus' first victim.
According to police reports via NHK, the 27 year-old's computer was infected with a type of computer virus previously unseen in Japan. The virus enabled a third party the ability to control the host computer.
This is apparently what happened to animator Masaki Kitamura, who's worked on a whole host of projects, such as Yu-Gi-Oh! (storyboard), Zone of the Enders: Idolo, Tiger & Bunny (episode director), and Mobile Suit Gundam 00 (storyboard, assistant director, and episode director).
"I will ram into pedestrian paradise, and after stabbing indiscriminately with a knife, I will commit suicide.
In July, a message appeared on the Osaka city inquiry page, which read, "I will commit a massacre in Otaroad next Sunday. I will ram into pedestrian paradise, and after stabbing indiscriminately with a knife, I will commit suicide." Otaroad is in Nipponbashi, Osaka's geek district. It's an area with heavy foot traffic—a pedestrian paradise, if you will. The threat seemed similar to the 2008 attack in Akihabara in which seven people ended up dead and ten were injured.
