Photocopy of a declassified report on Keizaburo Koyama. This page further elaborates that Confidential Informant SE N-1 has, on several occasions, mis-translated Japanese names. In this case, he mistook the name "Iwao Oyama" for Keizaburo Koyama. The informant said that his original source for the names, a Japanese newspaper, has since been destroyed. The informant went on to say Koyama came to the United States in 1915, his wife, Teru, followed in 1918, and that his son was born in Oregon in 1928. The informant said that Koyama was on the executive committee of the Japanese Association of Portland in 1938 and 1939 and currently worked as a dentist at 6 S.W. 6th Avenue, Portland, Oregon and resided at 8306 S.E. Washington, Portland, Oregon. The informant advised the Federal Bureau of Investigation about a newspaper article in the G.N. Daily News dated January 28, 1941 that "drastic changes" were taking place in the Portland Japanese Association's internal structure and that Koyama was appointed as a member of the research committee. A translation of another article from the N.A. Times dated January 28, 1941 provided by the informant listed Koyama as one of the consuls for the Japanese Golf Club for Portland, Oregon.
