By advancing a broad research program for homelessness and poverty, this book provides the essential understanding of how state rescaling ensnares homeless and impoverished people in the interplay of the state, domiciled society, public space, urban class relations, social movements, and capitalism. Its three angles-- national states, public and private spaces, and urban social movements-- uncover the hidden dynamics of rescaling that emerge, and are resisted, at the fringes of mainstream society and its housing regimes/classes. Evidence is drawn from Japanese cities where the author has conducted long-term fieldwork and develops robust urban narratives by mobilising spatial regulation theory, metabolism theory, state theory, and critical housing theory. The book cross-fertilises these Lefebvrian, Gramscian, Harveyan, and other Marxian strands through meticulous efforts to reinterpret both old and new texts. By building bridges between classical and contemporary interests, and between the theories and Japanese cities, this book attracts various audiences in geography, sociology, urban studies, and political economy.
