Since before the American Civil War, African American and Japanese encounters produced relationships and discourse of knowledge that transcended Eurocentric conceptions of civilization and hierarchies of personhood. Black Transnationalism and Japan introduces the diverse activity and intellectual movements created, shaped, and led by Japanese and African American people. While some Pan-Asianisms and Pan-Africanisms urged a uniting of colonized spaces against the colonizer, and were often expressed in the form of decolonization movements, this volume introduces various transnational phenomena that transcended such dichotomies. Black American-Japanese transnational encounters often occurred on the non-state level from within the two new competing empires of America and Japan. Such transnational encounters reveal not only heretofore hidden historical actors, friendships, and solidarities, but also innovative cultural productions that challenged hierarchies of race, culture, and imperialism.
