Photocopy of a declassified file on Keizaburo Koyama by the Federal Bureau of Investigation. This page goes into greater detail the reasoning for interning Koyama. The FBI has labeled the Fatherland Society as "one of the most aggressive and active of the Japanese nationalist organizations...It's members are selected by reason of their intense loyalty and belief in the deity of the Mikado." As for the Japanese Chamber of Commerce, the FBI noted the organization's fundraising efforts to support Japan during the Sino-Japanese War and for its goal of promoting Japanese culture abroad. The FBI felt that this was being done to the detriment of raising American born Japanese children as proper Americans. Per notes taken from Tomishichi Akiyama, a fellow Issei arrested by the FBI, the Japanese Association felt that they were under FBI surveillance and recommended greater secrecy during their meetings to avoid trouble.
