When asked where he gets ideas from, Urasawa said "I have been illustrating all my life. Inspiration is everywhere, when I get in the bath, when I get out. It's whether you are perceiving these ideas and whether you are able to catch them." He also said that he does not worry about what the readers want, and simply draws stories that he finds interesting. The artist said that while manga is often looked at as simple, he makes sure to use subtleties to show dramatic expressions and convey emotion, claiming "You won't find two expressions that are the same" in his work.
