The Honorable William Marutani was born in Kent, Washington. With the enforcement of Executive Order 9066, Marutani was forced to leave his classes at the University of Washington and sent to Fresno Assembly Center in 1942, and later Tule Lake concentration camp. He was released to attend Dakota Wesleyan University in Mitchell, SD in the fall of 1942 as a pre-law student.

After being rejected by the U.S. Navy for being classified as a 4-C enemy alien, Marutani was finally able to serve by joining the Army where he was assigned to the Military Intelligence Service. Following his service, Marutani attended law school at the University of Chicago and moved to Pennsylvania for a six-month clerkship, where he stayed until 1975, when he was appointed to the bench of the Philadelphia Court of Common Pleas.

Marutani became active in the Japanese American Citizens League (JACL) and served in many different positions. Marutani was appointed to serve on the nine-member Commission on Wartime Relocation and Internment of Civilians (CWRIC) that was created by President Jimmy Carter to investigate matters concerning the wartime incarceration of Japanese Americans. Marutani was the only Japanese American to serve on the commission. (April 11, 2008)
