In 1942 after the Pearl Harbor attack, ten U.S. concentration camps were built to hold 120,000 Japanese. Seventy percent of these people were American citizens. Each of these camps became highly organized by the people who lived in them. They included stores, bakeries, churches, beauty shops, cemeteries, schools, and more. This is a picture of some Manzanar high school students at recess.
