Book excerpt: This book traces the origins and transformations of a people-the Zainichi, or Koreans “residing in Japan.” Using a wide range of arguments and evidence-historical and comparative, political and social, literary and pop-cultural-John Lie reveals the social and historical conditions that gave rise to Zainichi identity, while exploring its vicissitudes and complexity. In the process he sheds light on the vexing topics of diaspora, migration, identity, and group formation.
