It's pre-photography, a fossilization of time, Americans have done the Zen garden to death. I wanted to do something different.

Humans have changed the landscape so much, but images of the sea could be shared with primordial people. I just project my imagination on to the viewer, even the first human being. I think first and then imagine some scenes. Then I go out and look for them. Or I re-create these images with my camera. I love photography because photography is the most believable medium. Painting can lie, but photography never lies: that is what people used to believe.

Art always helps religion; it became an inseparable phenomenon when human beings gained consciousness.

I didn't want to be criticized for taking low-quality photographs, so I tried to reach the best, highest quality of photography and then to combine this with a conceptual art practice. But thinking back, that was the wrong decision [laughs]. Developing a low-quality aesthetic is a sign of serious fine art-I still see this.

I want to put it back together now, this artistic expression that contains religious feeling. I want to investigate: What was the origin? What's happened in the human mind? Can we trace back the moment of the creation of human consciousness? And why did only humans gain consciousness, not other animals? So, evolution? I don't know whether or not I can believe evolution. Maybe we wait for another 100,000 years and then apes get consciousness.

The Buddhist concept is that it takes 48 days to get near this state [of death]. So it's a slow process, moving into, not a permanent death, but the world of the dead.

Fossils work almost the same way as photography as a record of history. The accumulation of time and history becomes a negative of the image. And this negative comes off, and the fossil is the positive side. This is the same as the action of photography.
