I should have posted this last week. I went for lunch on June 8 in Akihabara, not far from my office, and passed the street corner where a year ago to the day some nut went on a stabbing spree, killing seven people. News reporters were gathered around the spot where people had placed flowers as a memorial. Akihabara is always crowded, pretty much like the rest of Tokyo's business and shopping areas, and it's hard to imagine what I would have done if I had been one of the people who just happened to be strolling along the street that Sunday. I had passed this street corner dozens of times before the murders and dozens of times since. Random violence like the Akihabara murders is the scariest kind of violence because it could happen anywhere at anytime. Yet, just like with earthquakes, we generally don't let the fear of these kinds of incidents stop us from going about our daily lives.
