No, not at all. It's the same as an earthquake. If something's going to happen, it's going to happen. I'm much more afraid of Mount Fuji erupting or the earth splitting beneath me.

It crossed my mind coming into Tokyo. But the attacks are so random -- there's more chance of a plane or car crash. The more we keep on with our lives the harder it is for terrorists to keep their objective.
Within 3 years it's likely. The day after the London attack I went to Nagatacho and there were so many police there. But I don't worry about terrorism in the real world -- that seems so far away.
We don't really know what al-Qaeda think and Japanese protection against terrorists is very weak compared to the U.S. I'm about 50 percent worried about an attack.
Tokyo doesn't have the same police presence as other major cities, but I think Japan's system, where people will contact the police if they see something suspicious, is effective.
I'm from New York, so I was there during 9/11. I think all cities of the world's G-8 countries are targets, but there's not much you can do. If someone really wants to carry out an attack, they can.
