Why was evidence of Japanese bacteriological and chemical warfare not presented at the Tokyo War Crimes Tribunal and what part did America play in the conver-up of these crimes?

Fresh evidence from newly released sources clarifies the shocking story of Japanese human experiments in Manchuria during the War, and reveals the true extent of the subsequent US cover-up.

In the aftermath of World War II, the Allied intent to bring Axis crimes to light led to both the Nuremberg trials and their counterpart in Tokyo, the International Military Tribunal of the Far East. Yet the Tokyo Trial failed to prosecute imperial Japanese leaders for the worst of war crimes: inhumane medical experimentation, including vivisection and open-air pathogen and chemical tests, which rivaled Nazi atrocities, as well as mass attacks using plague, anthrax, and cholera that killed thousands of Chinese civilians. In Hidden Atrocities, Jeanne Guillemin goes behind the scenes at the trial to reveal the American obstruction that denied justice to Japan’s victims. Responsibility for Japan’s secret germ-warfare program, organized as Unit 731 in Harbin, China, extended to top government leaders and many respected scientists, all of whom escaped indictment. Instead, motivated by early Cold War tensions, U.S. military intelligence in Tokyo insinuated itself into the Tokyo Trial by blocking prosecution access to key witnesses and then classifying incriminating documents. Washington decision makers, supported by the American occupation leader, General Douglas MacArthur, sought to acquire Japan’s biological-warfare expertise to gain an advantage over the Soviet Union, suspected of developing both biological and nuclear weapons. Ultimately, U.S. national-security goals left the victims of Unit 731 without vindication. Decades later, evidence of the Unit 731 atrocities still troubles relations between China and Japan. Guillemin’s vivid account of the cover-up at the Tokyo Trial shows how without guarantees of transparency, power politics can jeopardize international justice, with persistent consequences.

From 1932 to 1945, in a race to develop germ warfare capability for the Imperial Japanese military thousands of Japanese doctors, nurses and scientists willingly took part in what was known at the time as "the secret of secrets": horrifying experiments on innocent Chinese men, women and children, as well as experiments on American prisoners of war. An elite group known as Unit 731, led by Dr Shiro Ishii (Japan’s answer to Joseph Mengele), infected thousands of prisoners with virulent strains of typhoid, plague, cholera and other epidemic diseases. Germ warfare campaigns were launched against China, cities and towns were hit with biological bombs. Yet after the war, General Douglas MacArthur struck a deal with these doctors, shielding them from accountability for their crimes. Provocative, compelling and alarming, A Plague Upon Humanity exposes one of the most shameful chapters in human history – the story of Japan’s deadly biological warfare programme, and how it was hidden from the history of World War Two.

First Published in 2002. Routledge is an imprint of Taylor & Francis, an informa company.

This book exposes Unit 731 as being the largest bacterial warfare force in the history of the Second World War. Manufacture and the use of biological weapons, the entire process of preparation and implementation of germ warfare, with the reflection on war and human nature, medical and ethical issues, is given by the testimony of the veterans of Unit 731. This evidence is provided by the surviving Chinese labourers and the families of the victims. The book focuses on five aspects: first, the inhuman medical crimes of Unit 731 weapons, the biological combats, and human experiments; secondly, the war damage and the postwar effects of biological war by Unit 731 brought to China and other Asian countries; thirdly, the survey and cover-up at the Khabarovsk War Crime Trials; fourthly the protection status of the site with development status of the exhibition and international exchanges of the Unit 731 Museum; fifthly and finally, there is a separate chapter discussing Japanese chemical warfare.
