- Riichi Miyake: Arata really loves pleasure in a hedonistic way, and he also tries to make architecture which has a common language with other spheres of society. Not only from the craftsmanship, not only from the producing system, but also in a very metaphysic way, also in a very literary way or in any kind of a cultural field. He was quite brilliant in that sense.
- Koji Taki: In Isozaki the relationship between the Western influence and the Japanese tradition is very delicate. To put it very simplistically, I regard him as one of a handful of Japanese architects who are firmly committed to the Western method of thinking. I say this because each culture has its specific and unique way of thinking, and this has a lot to do with the way space is conceived in that culture. Spaces in the West are basically volumes confined by walls, whereas Isozaki conceives of space in Japan as being darkness; space which only appears and emerges as the viewer moves through it.
- Arata Isozaki: Through my work as an architect I have realized that unless we consider architecture as a concept of a higher order, as a meta-concept, we will not be able to find new solutions. So there's a need for establishing an architectural theory, or in more general terms, a theory for architecture as a category, and of late I have been thinking of architecture as a possible foundation for contemporary thought that is to say contemporary philosophy, and with this in mind I am trying to approximate a new architectural theory.
