Interviewer:How did you come up with the idea for this project?
Watanabe: In recent years, there have been terrorist attacks all over the world, but Japanese people seem to be under the impression that these are things that happen in countries far away. However, if there were suddenly serial bombing attacks in the middle of Tokyo, what would happen? How would we deal with that? What if the culprits were teenaged boys? What if terrorists showed up who could use current technology to lead Japan around by the nose using their smartphones? These ideas were what formed the original concept. And then, thinking about possible acts of terror that could occur in Japan, I had to think about the systems in Japan as a country and how they work.
