This Handbook explores the challenges demographic change poses to today's Japan. The first part provides the fundamental data involved, and the subsequent two parts address the social and cultural aspects of Japan's demographic change. Parts four and five are dedicated to the political, economic and social security aspects of demographic change. The Handbook brings together a group of international scholars of various disciplinary backgrounds to take issue with the world's fastest demographic transition. Topics include the dynamics of gender roles, images of age, policy formation, labour market structures, pension system, living arrangements, ethical values, and many more. Against the background of Japan's demographic change, the latest developments in these fields are being introduced, and whenever appropriate set into a context of historical and/or international comparison. This Handbook is the first comprehensive publication in English on Japan's demographic change.
