Why were japanese put in internment camp?

Japanese Americans were placed in internment camps during World War II due to widespread fear and paranoia following the attack on Pearl Harbor in 1941. The U.S. government, influenced by racial prejudice and concerns about national security, viewed Japanese Americans as potential threats, despite many being U.S. citizens. This resulted in the forced relocation and incarceration of around 120,000 individuals, primarily from the West Coast, in camps across the country. The internment is now widely recognized as a grave injustice and violation of civil rights.
