For me, trying to expand the energy to make one movie in Hollywood would be the equivalent in terms of energy to making 10 movies in Japan.

I'm not a big fan of violent movies, it's not something I like to watch. And it's not my aim or goal to make a violent movie. My characters are very important, so when I'm trying to depict a certain character in my movie, if my character is violent, it will be expressed that way in the film. You cannot really deny what a character is about. To repeat, my movie end up becoming violent, but I don't start with the intent of making violent movies.

As a filmmaker, you've got to have a nose for what's going on culturally. You have to feel it. It doesn't have to be manga or music, but you need some kind of antenna. That's very important.

You can't really make something or make a movie and feel all through the process that it's a painful thing. It's not possible to do that.

The reason I like incorporating the Yakuza into my movies - all their actions, everything they do, you can say 'It's ok because he's a Yakuza'. Changes happen very quickly in their world. If you were trying to make a movie about politicians, it would takes years and years for something to change; whereas for Yakuzas, it could only take one night and things can change dramatically.

I've been making movies for a long time. The Japanese way of making movies has become second nature to me. To get away from that, I really try to surround myself with younger staff and approach making movies not like a veteran of the industry but always as a beginner and a rookie.
