The real villain of the Japanese internetment camp program was JJ McCloy (1981): https://www.nytimes.com/1981/11/04/us/ex-aide-calls-japanese-internment-humane.html https://www.nytimes.com/1981/11/04/us/ex-aide-calls-japanese... > "John J. McCloy, former Assistant Secretary of War, today defended the internment of Japanese-Americans in World War II as ''reasonably undertaken and thoughtfully and humanely conducted.'' Mr. McCloy, one of the key Government officials who oversaw the relocation program, said he might again support the wartime resettlement of United States citizens because of their national heritage." It's true that there were actual Japanese government agents operating in the USA at the outbreak of WWII, but they were comparable in number to the German and Italian agents who were also US citizens. An overview of the Japanese government's activities from the Office of Naval Intelligence is here (Office of Naval Intelligence, 1941) http://www.mansell.com/eo9066/1941/41-12/IA021.html http://www.mansell.com/eo9066/1941/41-12/IA021.html In comparison to internment of 112,000 Japanese-Americans ancestry (and seizure of property), some 11,500 people of German ancestry and three thousand people of Italian ancestry were incarcerated on suspicion of being foreign agents, out of a population of 1.2 million German-Americans and 2.4 million Italian-Americans. https://encyclopedia.densho.org/German_and_Italian_detainees/#Comparison_to_the_Japanese_American_Experience https://encyclopedia.densho.org/German_and_Italian_detainees... Conclusion: the Japanese internment program was just another example of blatantly racist government policy, of the same kind that motivated Nazi 'master race' thinking. Incidentally, McCloy was also a primarily responsible for the early release of Nazi industrialists from prison in post-WWII Germany.
