The study of Japanese politics is a vibrant field that has changed substantially over time. This work provides an in-depth exploration of current research. Moreover, it addresses theoretical questions and empirical issues that will guide research on Japan for years to come and thus serves as a key resource for scholars, students, and practitioners. Through more than 40 chapters by leading specialists, the Oxford Handbook of Japanese Politics examines major aspects of both domestic politics and international relations. In addition to providing a broad overview of contemporary Japanese politics, the chapters are united by a shared question: what is the nature and quality of Japanese democracy? Contributors consider this matter alongside their individual subjects, which together comprehensively address the central research topics of the field.
