Photocopy of a declassified report on Keizaburo Koyama. Confidential Informant N1 provided another translated article from the North American Times dated February 14, 1941 which stated that Koyama was appointed to the Industrial Department of the Japanese Association of Oregon, which was reorganized as a new Japanese Chamber of Commerce. On March 5, 1941, Koyama was appointed as a miscellaneous chairman for the new Chamber. The report by Quinn notes that Koyama was "fairly well acquainted" with the local influential Portland Japanese community. He notes that Koyama is also on the Financial Department of the Japanese Chamber of Commerce for the 31st District (Linnton District of Portland). Additional information was provided by Dr. A. F. Weeks of the State Board of Dental Examiners and a Mrs. Crew of the north Pacific Dental College. Quinn notes that Koyama shares his business office with three other Japanese nationals - Dr. George Shiomi, Dr. D.N. Unthank, and Howard Nomura. Paul Yamada, a Nisei, states that prior to becoming a dentist, Koyama worked in the Oregon News (Oshu Nippo) with Iwao Oyama, its current publisher.
