What does it mean when many Japanese Americans on the West Coast were placed in internment camp?

The internment of Japanese Americans on the West Coast during World War II refers to the forced relocation and confinement of around 120,000 individuals, two-thirds of whom were U.S. citizens, following the attack on Pearl Harbor in 1941. The U.S. government justified this action by citing national security concerns, fueled by wartime hysteria and racial prejudice. Many of those interned lost their homes, businesses, and personal property, and the internment is now widely recognized as a violation of civil liberties and a grave injustice. In later years, the U.S. government formally apologized and provided reparations to survivors.
