This book explores the politics of anti-nuclear activism in Tokyo after the Fukushima nuclear disaster of March 2011. Analyzing the protests in the context of a longer history of citizen activism in Tokyo, it also situates the movement within the framework of a global struggle for democracy, from the Arab Spring to Occupy Wall Street. By examining the anti-nuclear movement at both urban and transnational scales, the book also reveals the complex geography of today’s globally connected social movements. It emphasizes the contestation of urban space by anti-nuclear activists in Tokyo and the weaving together of urban and cyber space in their praxis. By focusing on the cultural life of the movement—from its characteristic demonstration style to its blogs, zines and pamphlets—this book communicates activists’ voices in their own words. Based on excellent ethnographic research, it concludes that the anti-nuclear protests in Tokyo after the Fukushima disaster have redefined social movement politics for a new era. Providing an analysis of a unique period in Japan’s contemporary urban history from the perspective of eyewitness observations, this book will be useful to students and scholars of Japanese Politics, Sociology and Japanese Studies in general.
