Photocopy of a declassified report on Keizaburo Koyama by Vincent M. Quinn on January 14, 1942. It states that Koyama was born on October 7, 1897 and immigrated to Seattle, Washington in 1914. He was working as a dentist in Portland, Oregon when the order for his arrest was issued on December 8, 1941. He was picked up on December 10, 1941 and is currently confined in Camp Missoula, Montana. The document further details that a prior report was incorrect in stating that Koyama received the Japanese Foreign Minister's Cup for distinguished services abroad.
