One of the major things that led to the internment camps was an incident where a Japanese fighter pilot who was shot down during the attack on Pearl Harbor was helped by Japanese-Hawaiians who had lived in US terriorty for years. The Japanese-Hawaiians attacked the guard, helped the pilot escape, burned down a neighbor's house, and took hostages. This caused many Americans to fear that the war effort would be sabotaged by ethnic Japanese (and Germans/Italians, who were spied upon but not placed in camps in large numbers as it would have been infeasible to do so due to their high American population) citizens who had more loyalty to their homeland than their country. >The behavior of Shintani and the Haradas was included in an official Navy report dated January 26, 1942. The report's author Navy Lieutenant C. B. Baldwin wrote: "The fact that the two Niʻihau Japanese who had previously shown no anti-American tendencies went to the aid of the pilot when Japanese domination of the island seemed possible, indicate[s] [the] likelihood that Japanese residents previously believed loyal to the United States may aid Japan if further Japanese attacks appear successful." https://en.wikipedia.org/wiki/Niihau_incident https://en.wikipedia.org/wiki/Niihau_incident
