African American and Japanese people share a rich history of nearly two hundred years of transnational engagement and activity. African American writers discussed Japan as early as 1828, and, in the African American and abolitionist press, the 1860 Japanese Embassy to the United States inspired a perception of transnational solidarity between African American and Japanese people based on the shared experience of racial prejudice and the right of all men to participate in the affairs of the world. From the 16th century to the early 19th century, Japanese ideas surrounding Blackness were very different from the racial ideologies prevalent in Europe and later the United States. Japan’s victory in the Russo-Japanese War inspired African American admiration for Japan as a global leader in the fight against racism and imperialism, although Japan expanded its imperial activity across Asia throughout the early 20th century. At the 1919 Paris Peace Conference, the Japanese racial equality bill made Japan even more of a symbol of the fight for racial equality to African American civil rights leaders and writers. Throughout the 1920s and 1930s, many Japanese intellectuals were inspired by the African American struggle for civil rights, as well as their transnational engagement with African American people, to promote anti-imperialism within Japan. Meanwhile, in the 1930s, pro-Japanese organizations proliferated across the United States and influenced tens of thousands of African American people. The Japanese attack on Pearl Harbor ended much, but not all, African American sympathy for Japan. The FBI was concerned that Japanese military agents would racially agitate African American people into subversive activity. As part of the war effort, the Japanese military did plan pro-Japanese racial propaganda targeted toward America’s Black people. During the Occupation period, many Japanese people adopted negative racial attitudes toward Black people. At the same time, during the postwar period, many Japanese and African American people shared transnational relationships free from the increasing racial prejudice perpetuated by the American state. Japanese and African American relations, as well as representations and perceptions of Black people in Japan, have continued to change throughout the 21st century.
