The era sandwiched between the 1924 US Immigration Act and the 1941 Japanese attack on Pearl Harbor marks an important yet largely buried period of Japanese American history. This book offers the first English translation of Yasuo Sakata's seminal essay arguing that the 1930s constitutes a chronological and conceptual "missing link" between two predominant research interests: the pre-1924 immigration exclusion and the mass incarceration of Japanese Americans during World War II. The anthology pays tribute to Sakata's role as a foremost historian of early Japanese America and transpacific migration while providing an opportunity for a younger generation of scholars to reflect on his contributions and carve out a new area of research in Japanese American history. Original and translated essays from scholars of varied backgrounds and generations explore topics from diplomacy, geopolitics, and trade to immigrant and ethnic nationalism, education, and citizenship. Together, they attempt to catalyze further research and writing based on the thorough and careful analysis of primary-source materials, an effort that Sakata spearheaded in both the United States and Japan.
