Photocopy of a declassified file on Keizaburo Koyama by the Federal Bureau of Investigation. The document speaks on Koyama's hearing at Fort Missoula, Montana and being found to be an enemy alien. The decision was based largely on Koyama having a subscription to the magazine put out by the Sokoku Kai. The panel felt that his association with the Hiro Fuji, organizer of the chapter, gave a sense of "loyalty and subservience to the Imperial Government of Japan."
