I try to dig deep into the well of my subconscious. At a certain moment in that process, the lid is opened and very different ideas and visions are liberated. With those I can start making a film. But maybe it's better that you don't open that lid completely, because if you release your subconscious it becomes really hard to live a social or family life.

In fact, I am a pessimist. But when I'm making a film, I don't want to transfer my pessimism onto children. I keep it at bay. I don't believe that adults should impose their vision of the world on children, children are very much capable of forming their own visions. There's no need to force our own visions onto them.

I've never studied psychology.

But remember this, Japanese boy... airplanes are not tools for war. They are not for making money. Airplanes are beautiful dreams. Engineers turn dreams into reality.

To be born means being compelled to choose an era, a place, a life. To exist here, now, means to lost the possibility of being countless other potential selves.. Yet once being born there is no turning back. And I think that's exactly why the fantasy worlds of cartoon movies so strongly represent our hopes and yearnings. They illustrate a world of lost possibilities for us.

I do believe in the power of story. I believe that stories have an important role to play in the formation of human beings, that they can stimulate, amaze and inspire their listeners.

You always have to appeal to your audience. You always have to consider how well your project will do in terms of admissions. I abandoned many stories because of that. But I don't get too down about it. It's something I accepted from the time I decided to work in films. I could always do something else if I got sick of it, like draw manga, or make my own films. I found it pointless sitting in my house not working, though I'd like to go on extended vacations from time to time.
