Congress implemented executive order 9066 on March 21, 1942
You're being taken, follow me
This was significant because the Bombing of Pearl Harbor was the main cause behind the US getting involved in WW2. It infuriated the citizens of the US and made everyone want to fight back. The next day FDR would ask Congress for a declaration of war which would soon be accepted.
Where are we going mother?
I don't know my dear child
On March 21, 1942, Congress implemented executive order 9066 created by Franklin D Roosevelt allowing Japanese exclusion. He was afraid of the possibility of potential Japanese spies on our own land so he felt safest isolating them.
We're losing our property back home and we can't do anything about it
Once the order was passed, the Japanese had a short amount of time to voluntarily evacuate. Eventually, the Japanese were taken involuntarily out of their homes and forced to be moved to an internment camp, no matter the circumstances.
The Japanese people had no idea where they were going other than the fact that there would be other Japanese people there. Families were scared and children would often ask where they were being taken and the parents weren't able to reassure them because they didn't know either.
Many families lost their stores and property while in the internment camps because they were stuck in the camps and couldn't do anything about it. It's estimated that around $1.3 billion dollars worth of property was lost while the Japanese were taken away.
The Japanese were permanently stuck in the camps and sometimes the only way the men could get out was if they joined the military. But for the most part, Japanese families would live on in the camps until the war was over and they were set free. The war lasted until August 6, 1945, when the US dropped the atomic bombs on Hiroshima and Nagasaki.
