Civil society in Japan is a large and multifaceted sphere with a diversity of actors pursuing various social, political, and economic objectives. The sphere has experienced major waves of transformation in the post-1945 era, especially in the 1990s when volunteering and nonprofit activities came to the forefront of political and popular attention. This handbook brings together twenty-one leading experts to provide comprehensive and up-to-date analyses of civil society in Japan. What is the history of Japanese civil society and how has it evolved in recent decades? Who have been the key participants and what are their objectives? How have international actors and conditions influenced civil society in Japan? More broadly, what do recent developments in Japanese civil society tell us about the condition of democracy, state-society relations, and the public sphere in the country? And how might Japanese civil society develop into the future? The contributions to the handbook offer innovative perspectives based on the most-recent fieldwork and data available. The handbook is divided into three sections: Institutions, Justice and Transnationalism. Topics include nonprofit organizations, volunteering, philanthropy, new media, gender, pacifism, nuclear power, territorial politics, international cooperation and transnational solidarity. The volume will be valuable for scholars in both research and teaching as well as essential reading for anyone wanting to understand the diversity and vibrancy of Japanese civil society today.
