You never know how a film will play, whether it will be successful or not, or whether it will touch the audience. I always said to myself that whatever happens, big audience or small, that I would not let the results have an impact on my way of working. But it would be a bit silly for me to change my methods when I have a big success. That means my methods work well.

I managed to work for more than 50 years with just paper, pencils and film. My son's generation and the one coming up after can't work with just paper and pencils any more. I managed to avoid using a computer. I don't even have a cellphone. I feel lucky I managed to live like that.

The villains are all parts of me. For years I've been wondering what it would be like if all those negative elements were forced onto the main character's side. I can understand a character with that kind of anger.

In the past, humans hesitated when they took lives, even non-human lives. But society had changed, and they no longer felt that way. As humans grew stronger, I think that we became quite arrogant, losing the sorrow of 'we have no other choice.' I think that in the essence of human civilization, we have the desire to become rich without limit, by taking the lives of other creatures.

When I start creating a villain, I start liking the villain and so the villain is not really evil.

I intend to work until the day I die. I retired from feature-length films but not from animation. Self-indulgent animation. It's nice that I have the mini-theater in the museum. Most of the museum visitors attend the mini-theater screenings and we've never had a complaint about the quality of the films. I'd like to continue to make films that leave the audience satisfied, but I also think it's pointless unless I offer them the kind of animation they can't get anywhere else. They're fun to do. They're short so it's less stressful.

Since I am a person who starts work without clear knowledge of a storyline, every single scene is a pivotal scene.
