Book excerpt: Despite a master narrative of cultural and racial homogeneity, Japan is home to diverse populations. In the face of systematic exclusions and marginalization, minority groups have consistently challenged the subordinate identities imposed by the Japanese majority. Japan's Minorities addresses a broad range of issues associated with the six principal minority groups in Japan: Ainu, Burakumin, Chinese, Koreans, Nikkeijin, and Okinawans. The contributors to this volume show how an overarching discourse of homogeneity has been deployed to exclude the historical experience of minority groups in Japan. The chapters provide clear historical introductions to particular groups and place their experiences in the context of contemporary Japanese society.
