120,000 people were sent to the internment camps.
The internment camps ended in 1945.
A lot of the Japanese Americans sent to the internment camps were born in the United States and many had never even been to Japan.
The adults were allowed to work if they chose to for $5 per day.
The govenment decided to allow the prisoners to leave the camps if they joined the U.S. Army but only 1,200 did.
In 1 of the camps there was a kid who grew up to be a famous actor in Star Trek, his name is George Takei.
