Even as many of their families were incarcerated, more than 30,000 Japanese Americans volunteered for military service.
Most were members of the 100th Infantry Battalion from Hawaiʻi and the 442nd Regimental Combat Team, segregated units that fought together in Europe. In some of the most grueling battles of the war, they became among the army’s most decorated units. More than six thousand other Japanese Americans served as translators and interpreters for the Military Intelligence Service. Japanese American women also served in the Women’s Army Corps.
