What happened to Japanese-Americans during World War 2?

Answer 1

they were put into camps were they had to live away from public for safety reason as the USA were paranoid of other attacks. They were not treated badly in these camp but just kept away from the public
They were put in internment camps because the government thought there were spies. Only those Japanese and Americans of Japanese descent who lived on the West Coast of the United States were interned. The Japanese and Americans of Japanese descent in Hawaii were not incarcerated!
