What happened that led up to the forming of the japanese interment camps?

The attacks on pearl led to the forming of the Japanese interment camps as one Japanese spy had led to the overall planning of how the raid would have gone. If not for him the Japanese would still have attacked but it is still debated wether or not it would have been as affective as the damage done on the original attacks of Pearl Harbor. This man was Takeo Yoshikawa and his relay of information ultimately led to the Americans leading to the idea of the Internment camps. This was just one way to resolve the majority of American outrage at the time. This for President Rosevelt at the time seemed like a sure way to make the public feel safe and deter any chance of a spy set a foot on American soil. Ultimately none of the Japanese were found to be spies according to my sources but if there was please correct me. But although some may find it immoral it was a way to rally the American people but also allow them to cool down. The country was attacked and some justice had to be done or else the moral and unity of the country would be in shambles. This was a questionable act that made many Americans feel like they had justice and although I personally do not like the action that was taken ultimately the conclusion did help in some minor ways.
