The lives of Roy Matsumoto and thousands of other Americans of Japanese ancestry were changed Dec. 7, 1941, when Japan attacked the U.S. naval base at Pearl Harbor.

Matsumoto, born in Los Angeles and a graduate of Long Beach Polytechnic High School, was classified an enemy alien and sent to a concentration camp in Jerome, Ark. Eager to prove his loyalty to the country of his birth, he enlisted in the Army and became a war hero.

Matsumoto’s story is included in a documentary about the Japanese American men who were incarcerated in concentration camps, enlisted in the U.S. military, and volunteered to become linguists in the Military Intelligence Service in the Pacific Theater during World War II. The film, “Honor and Sacrifice: Nisei Patriots in the MIS” (Stourwater Pictures) focuses on the experience of Matsumoto “and his personal journey – from being born an American, raised in Japan, sent to Jerome, Ark. concentration camp as a young man, to enlisting in the U.S. Army and becoming a hero in fighting the Japanese Army in Burma as part of the U.S. military unit known as Merrill’s Marauders.”

Stourwater Pictures produced the 17-minute documentary for Washington State’s Office of the Superintendent of Public Instruction, and is raising money to expand the documentary to PBS length.
