I think my performances did keep getting better. I also think that I managed to give Godzilla a distinct character. I'm very proud of that. - Kenpachirō Satsuma

I have now done seven films as Godzilla, and I believe I have achieved most everything I have wanted to do inside the costume... Most importantly, I have always felt Godzilla should express its emotions, which is very difficult given the range of movements and expressions the suit can make. So, whatever Godzilla does - roaring, spewing his radiation breath, communicating with Godzilla Junior - I always try to add little movements that will show his emotional state, like moving his fingers, or a short glance. The Heisei Godzilla [has] a very different personality than the old Godzilla. He is very animalistic, always in motion. But I believe Godzilla is a very emotional creature.

I had to wear an oxygen mask both in the water and on land because of the carbon monoxide. I fainted four times during the first day of filming. We were shooting the scene in which Godzilla emerges from the water as he approaches Hong Kong. I wasn't warned about the carbon monoxide, so I wasn't wearing an oxygen mask. We were shooting in water, so nobody could just run up to me when they saw me acting strangely. We were filming a long shot, so nobody was very close to me. The members of the staff didn't realize I'd fainted that first time until they started opening up the costume so I could get out.

[Godzilla kenpo] is a combination of karate and the kinds of moves I make while playing Godzilla. I developed it to help me from becoming too worn out while playing Godzilla.
