 Once the United States entered the war and anti-Japanese sentiment began to circulate, Americans increasingly reacted with racism and hostility, viewing people of Japanese descent as enemies regardless of U.S. citizenship.The U.S. government expressed concerns about the loyalty of the Japanese people living in America and about Japanese spies sending information to Japan.As a result, the Treasury Department froze the assets of all citizens and resident aliens who were born in Japan, and the Department of Justice arrested some 1,500 religious and community leaders as potentially dangerous enemy aliens.
