"I think that one of the visions that is closest to reality is the cardboard city in the subway station in Tokyo, which is based very closely on a series of documentary photographs of people living like that and of the contents of the boxes. Those are quite haunting because Tokyo homeless people reiterate the whole nature of living in Tokyo in these cardboard boxes, they're only slightly smaller than Tokyo apartments, and they have almost as many consumer goods. It's a nightmare of boxes within boxes."
