Answer: As a result of anti-Japanese prejudice and fear. Japanese Americans were more isolated from other Americans. The Japanese were of a totally different cultural and racial background than most Americans, whereas Italian and German Americans were, like other Americans, of European cultural descent.
- Suspicious of anyone of Japanese heritage, the government restricted the civil liberties of Japanese Americans. In February, 1942, President Roosevelt issued Executive Order 9066, which allowed the Secretary of War to designate certain areas as military zones. FDR's executive order set the stage for the relocation of Japanese-ancestry persons to internment camps. By June of 1942, over 100,000 Japanese Americans were sent to such internment camps.
