You didn't do anything, but you're Japanese so you have to be here
Pearl Harbor was attacked on December 7, 1941 that set off a chain of events for the U.S. involvment in World War ll. Also, it heightened the racial tensions with Japanese Americans in the U.S.
If anyone even had "a drop" of Japanese blood in them, they would be placed in a camp. They were put there for no other reason than being Japanese.
In 1942, Anyone who was Japanese staying on the West Coast and wasn't in a camp yet, was forced to relocate farther East if they wanted to live. This caused about 13,000 Japanese Americans to relocate.
