World War II Japanese American Incarceration: Military and Civilian Service
Records related to Japanese Americans and the U.S. military during World War II reveal a complicated and often contradictory relationship. The federal government closely monitored Nikkei (Japanese emigrants and their descendants) communities as potential security threats, even as many members from these same communities served in military intelligence. Soon after all U.S. citizens of Japanese ancestry were reclassified to Category IV-C (aliens not suitable for service), the American government encouraged, solicited, and even demanded military enlistment—at a time their families languished in incarceration camps. And despite the many Japanese Americans who demonstrated their loyalty by entering uniformed service or in civilian roles, others were sent to federal penitentiaries for refusing the draft or for protesting their mistreatment in the military.
