After a decade of deregulation and economic liberalization the high levels of unity and social harmony that had been achieved during Japanfs decades of rapid economic growth is under threat. Social conflict is rapidly increasing, as economic disparities continue to grow, the economy remains stagnant, and new generations of workers find it increasingly difficult to find positions in the lifetime employment system. Against this backdrop, this book reports on the latest social psychology research into social conflict in Japan and how it is managed. Recognizing that social justice is an important factor in many forms of social conflict, the chapters each address the issue of conflict resolution from a social justice perspective. Part 1 analyses the growing disparities and perceptions of injustice in Japan today from the perspectives of social class, value, social principle, culture and legitimization. Part 2 includes empirical research on the mechanisms of conflict and cooperation in social relations.
