Look at London or Paris: they're both filthy. You don't get that in Tokyo. The proud residents look after their city.

Working in Tokyo has convinced me that, contrary to what people think, it is actually one of the world's most beautiful cities.

When you look at Japanese traditional architecture, you have to look at Japanese culture and its relationship with nature. You can actually live in a harmonious, close contact with nature - this very unique to Japan.

If you give people nothingness, they can ponder what can be achieved from that nothingness.

The speed of change makes you wonder what will become of architecture.

You can't really say what is beautiful about a place, but the image of the place will remain vividly with you.
