'The cities of today and tomorrow only exist within the twisted relations between the physical community and its network counterpart'. So argues Akira Suzuki, in the evocatively titled Do Android Crows Fly over the Skies of an Electronic Tokyo? The interactive urban landscape of Japan . This collection of essays by the editor of Telescope magazine and director of the Workshop for Architecture and Urbanism in Tokyo addresses the impact on Japanese cities of social and technological change. This is a very Japanese perspective with talk of one-person mansions, tatami mats and the aftermath of the Kobe earthquake, but also with mobile phones, network overloads and computer games. The illustrations have an immediacy that makes you feel you have just spent a weekend break in rapidly changing Tokyo - and brought home a few ideas for the future of our own cities. The book is published by AA Publications and costs £12.50.
