The internment affected approximately 120,000 individuals, the majority of whom were Japanese Americans.

The camps were surrounded by barbed wire and guarded by armed personnel, adding to the atmosphere of confinement. Despite these adversities, the internees sought to establish a sense of community, organizing schools, cultural events, and even newspapers to maintain morale and a semblance of normalcy amidst the difficult circumstances.

Properties were often sold at a fraction of their value or abandoned entirely. The financial impact was devastating, with estimates of total losses reaching hundreds of millions of dollars. After the war, few received any compensation, and rebuilding their lives proved challenging. This economic displacement had long-lasting effects on the Japanese American community, impacting generations to come.
