Researching Japanese War Crimes Records: Introductory Essays

Book excerpt: Japanese war crimes committed in Asia and the Pacific between 1931 and 1945 concerned few Americans in the decades following World War II. Japan’s crimes against Asian peoples had never been a major issue in the postwar United States, and—with the notable exceptions of former U.S. prisoners of war held by the Japanese—even remembrance of Japanese wartime atrocities against Americans dimmed as years passed. American attitudes about Japanese war crimes changed markedly following the 1997 publication of Iris Chang’s The Rape of Nanking.2 Chang’s moving testament to the Chinese victims of the sack of Nanjing in 1937 graphically detailed the horror and scope of the crime and indicted the Japanese government and people for their collective amnesia about the wartime army’s atrocious conduct. The bestselling book spurred a tremendous amount of renewed interest in Japanese wartime conduct in China, Korea, the Philippines, Southeast Asia, and the Pacific. The Rape of Nanking raised many issues that demanded further explanation. Why were the Japanese not punished as severely as the Nazis for their crimes? Did the United States suppress evidence of the criminal responsibility of activity by the emperor to ensure a smoothly running occupation of Japan? Did the U.S. government protect Japanese medical officers in exchange for data on human experimentation? Chang also charged the U.S. government with “inexplicably and irresponsibly” returning confiscated wartime records to Japan before microfilming them, making it impossible to determine the extent of Japan’s guilt.3 Others were convinced that the U.S. government retained highly classified documents that would prove Japanese guilt beyond doubt and implicate the highest levels of Japanese government and society in the crimes. These issues led concerned parties to investigate Japanese wartime records among the holdings at the U.S. National Archives and Records Administration (NARA) in College Park, Maryland, and at other U.S. government agencies. Thorough documentation of Japanese war crimes and criminal activities among these holdings seemed unavailable, leading to speculation of an official cover-up. Suspicions that the U.S. government was deliberately concealing dark secrets were fueled when, instead of finding the records they sought, researchers encountered a card stating the records had been “withdrawn for security reasons,” as well as when they received a notice that requested information could not be located.
