"Naming Tokyo" kicked off at the Palais de Tokyo in Paris in June, and it's going to travel to various art institutions for years to come. Every time it is shown, I'm developing the research and involving more and more people in it. The final conclusion of the work would eventually be to put up street signs in Tokyo with my names on them.

I follow these intimate connections of strangers and, surprise!, end up finding even myself in the work at some point.

I wanted to contribute to the landscape tradition in art. By now I guess we are comfortable with the thought that man has been everywhere or affected everything in nature.

National parks, zoos, protected areas, polluted seas - using the whole world as a readymade, I thought about it as a stage set. To activate a stage set you need a drama, an actor to offset it.

I'm very jealous of an era where people were inventing something so beautiful as the Concorde and thinking that's the next step. I'm jealous of an era when people thought, "Let's finally go to the Moon."

I think the wildest wildlife you can find these days is in Chernobyl, where wolves are running around breeding quite well in the nuclear disaster zones.

The space program caused so much future-thinking in culture. People who couldn't go to the Moon were building space-fantasy chairs and corsets and hairdos and anything that they could put their hands on.
