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.

And if I'm running away from something, I try to make myself face it and overcome that initial fear. As a director, I don't think it's possible to make a movie that you really don't want to make.

Bigger-budgeted films have more restrictions and less freedom to create. Because of this, I try to find freedom in the people I work with. I often work in ways I don't want to. It's more about controlling the situation. Lower-budget films are freer.

I don't mind ratings boards. As a viewer, you have the right not to see a film.

I don't make rules myself. I didn't study enough to be able to make them. I'm too stupid. I spend my whole life making movies, so I have to enjoy it. Even at times when we had a very tight and difficult schedule, it was always enjoyable. Of course I wonder if the film will be successful afterwards. It's wonderful if a film becomes successful as a result of the enjoyment that we had

I believe that every director's films reflect their lifestyle.

On the times when I used to make movies that were with a lower budget, nobody was expecting it to be a hit, and nobody was paying attention to what I was doing, and it was a free type of creative process. So, one way to reset myself is to go back to that kind of moviemaking.
