How were japanese-americans treated during world war ii?

Many Japanese-Americans were sent to internment camps, especially on the west coast of America. This was due to fear that they were spies for the Japanese government, which was fighting in opposition of the United States. This also happened on the west coast of Canada with Japanese-Canadians.

They were forced into confinement (called Japanese internment camps) if they were Japanese, or were from Japanese ancestry. The camps were usually very overcrowded.
