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'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.

I'm happy that my films were discovered by chance by foreign film festivals. That makes me realise more that there is a world outside Japan too. For me, it's an occasion to meet many people and to experience directly the response of international audiences to my films. But for me as a director, my attitude towards making films hasn't changed with the fame. I feel it's not good to change as a person anyway

When you try to be true to the script, changes occur. A script is there to show us a certain direction. But when you actually have the actors in and you start shooting the movie, you have the actor say a line and it doesn't sound right so you change it and make it different. It's the script that gives birth to these changes and the more you try to stay true to the script, the more that happens.

In Japan, violence isn't as controversial as it is in the West. Pornography is more restricted, but it's not hard to make a crazy, extremely violent film.

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.

When you are completely satisfied with what you have made, you're pretty much done as a director. So when that happens, that'll sort of be the end.
