The book “Sharing Tokyo. Artifice and the Social World” (Actar, 2023), edited by Mohsen Mostafavi and Kayoko Ota, questions how “artifice” and the “social world” can be mutually and constructively integrated so that the contemporary urban space can be shared by all. Taking the example of Tokyo, it takes up the two major traits in urban transformation – the large-scale development model on the one hand, and the small-scale model of neighborhood development or preservation on the other – and instead seeks alternative ideas and new strategies.
