The first two decades of the twenty-first century have witnessed a rise of populism and decline of public confidence in many of the formal institutions of democracy. This crisis of democracy has stimulated searches for alternative ways of understanding and enacting politics. Against this background, Tessa Morris-Suzuki explores the long history of informal everyday political action in the Japanese context. Despite its seemingly inflexible and monolithic formal political system, Japan has been the site of many fascinating small-scale experiments in 'informal life politics': grassroots do-it-yourself actions which seek not to lobby governments for change, but to change reality directly, from the bottom up. She explores this neglected history by examining an interlinked series of informal life politics experiments extending from the 1910s to the present day.
