In spite of facing continual discrimination, Japanese and Japanese Americans living on the U.S. west coast made lives for themselves. On December 7, 1941, everything changed. After the attack on Pearl Harbor (Hawaii), individuals saw every Japanese or Japanese American as a potential spy, ready and willing to assist in a mainland invasion at any moment. In February 1942, President Franklin Roosevelt signed an executive order that moved nearly 120,000 Japanese and Japanese Americans into 10 isolated relocation centers in Arizona, Arkansas, California, Colorado, Idaho, Utah, and Wyoming. This lesson is based on the National Register of Historic Places files "Manzanar War Relocation Center" and "Rowher Relocation Center Memorial Cemetery," and other related materials.
