Mike Masaru Masaoka (Japanese: 正岡優, October 15, 1915 – June 26, 1991) was born in Fresno, California. The family moved to Salt Lake City where Masaoka legally changed his first name to "Mike" and became a member of The Church of Jesus Christ of Latter-day Saints.
He became a champion debater and graduated in 1937 from the University of Utah in economics and political science. At the age of 25, Masaoka was named National Secretary and Field Executive of the Japanese American Citizens League (JACL) just before the outbreak of World War II.
Masaoka was a key player in JACL's decision to cooperate with the Japanese American internment during the war, seeing that resistance would be counterproductive and increase the tension between the Nisei and the FDR Administration. In his position as a national spokesman, he urged cooperation and opposed legal challenges to the government and advised the government on how to run the camps (thus to reduce friction between the internees and their captors). He also advocated the segregation of so‑called "troublemakers," though the War Relocation Authority cast the net more broadly than Masaoka had anticipated. The government used him as their liaison with the entire Japanese American population in the camps, although he himself was never imprisoned in a camp.
Masaoka was involved in leading the call for the formation of the Nisei 100th Battalion and 442nd Regimental Combat Team, and later served as publicist for the highly decorated volunteer units, so that the contributions (and heavy price paid) of the Japanese Americans would be known nationwide.
He later served as technical consultant for the 1951 film Go For Broke! which not only portrayed the heroics of the 442nd RCT and 100th Battalion, but also starred several veterans of the 442nd.
