Thomas Birke, a master of urban photography:
I went to Tokyo in the summer of 2008 for three weeks to take pictures of “the future”. What I found was even more impressive. The future began a long time ago in Tokyo, and so the whole city has a face, there has been so much organic growth – there is no master plan, the city has been shaped by individuals’ desires. The result is a structure that seems alive, even if you do not see the inhabitants, as usually the case with long-exposure photography.
