Theres an update on this:
"Update: Just saw the Japanese evening news, and the game connection has already been picked up on. The news mentioned that the killer was into fighting games and Final Fantasy. A Japanese person into Final Fantasy? Holy shit. Since most of the victims were stabbed in places like the neck, one "expert" was saying that it was through fighting games that Kanagawa learned about the body's weak points as assume things like that are only taught in video games."

The killer said he just wanted to see what it was to kill.
