Experiments included disease injections, controlled dehydration, biological weapons testing, vacuum chamber experiments on humans, vivisection, amputation, and standard weapons testing. While Unit731 researchers arrested by Soviet forces were tried at the December1949 Khabarovsk war crime trials, those captured by the United States were secretly given immunity in exchange for the data gathered during their human experiments. RT @EzbyThor: Japan's notorious Unit 731 personnel not only avoided punishment, they were even encouraged to continue their abominable experiments on mentally ill patients in Japan. But then finally he stopped. The report describes conditions of every subject precisely without mentioning what happened to them in the long run. If Ishii or one of his co-workers wished to do research on the human brain, then they would order the guards to find them a useful sample. "[68] The children of these women were tested in ways similar to their parents, with specific emphasis on determining how longer infection periods affected the effectiveness of treatments. Skeleton crews of Ishii's Japanese troops blew up the compound in the final days of the war to destroy evidence of their activities, but many were sturdy enough to remain somewhat intact. The term Unit731 can refer to the Harbin complex itself, or it can refer to the organization and its branches, sub-Units and their branches. This Russian was shot to death. Hisato then tried different methods for rapid rewarming of the frozen appendage. Venereal disease has been the bane of organized militaries since ancient Egypt, and so it stands to reason that the Japanese military would take an interest in the symptoms and treatment of syphilis. Date unspecified. [119] Later in that decade, journalists suspected that the murders attributed by the government to Sadamichi Hirasawa were actually carried out by members of Unit731. [40][41], During the final months of World WarII, codenamed Cherry Blossoms at Night, To determine effectiveness, Unit 731 herded captives together on a firing range and blasted them from varying ranges by multiple Japanese weapons, such as the Nambu 8mm pistol, bolt-action rifles, machine guns, and grenades. [91] Prisoners were repeatedly reused for experiments as long as they were healthy enough. [34][35]:xii,173. For example, female captives of childbearing age were sometimes forcibly impregnated so that weapon and trauma experiments could be done on them. Hyperemic conjunctivae. [114] The sentences doled out to the Japanese perpetrators were unusually lenient by Soviet standards, and all but two of the defendants returned to Japan by the 1950s (with one prisoner dying in prison and the other committing suicide inside his cell). The unit is estimated to have killed between 200,000 and 300,000 people. When most of the blood had been siphoned off and the heart was too weak to pump anymore, an officer in leather boots climbed onto the table and jumped on the victims chest with enough force to crush the ribcage, whereupon another dollop of blood would spurt into the container. [6] The United States covered up the human experimentations and handed stipends to the perpetrators. Unit 731 personnel conduct a bacteriological trial upon a test subject in Nongan County of northeast Chinas Jilin Province. One Russian shouted to the members of Unit731, demanding to be shot rather than used as an experimental object. [citation needed], In August2002, the Tokyo district court ruled for the first time that Japan had engaged in biological warfare. The prison cells had wooden floors and a squat toilet in each. Inside Unit 731, Japans Disturbing Human Experiments Program During World War II. Another group was clothed in summer military uniform and shoes; three had masks and another three had no mask. Unit731 was divided into eight divisions: Unit731 had other units underneath it in the chain of command; there were several other units under the auspice of Japan's biological weapons programs. The program received generous support from the Japanese government until the end of the war in 1945. [5] These operations killed tens of thousands with bubonic plague epidemics. "The fellow knew that it was over for him, and so he didn't struggle when they led him into the room and tied him down, but when I picked up the scalpel, that's when he began screaming. [131], In 1997, international lawyer Knen Tsuchiya filed a class action suit against the Japanese government, demanding reparations for the actions of Unit731, using evidence filed by Professor Makoto Ueda of Rikkyo University. In addition to the accusations of propaganda, the US also asserted that the trials were to only serve as a distraction from the Soviet treatment of several hundred thousand Japanese prisoners of war; meanwhile, the USSR asserted that the US had given the Japanese diplomatic leniency in exchange for information regarding their human experimentation. However, Unit 731 was likely the largest biological-warfare production facility in world history. The ministry backed down after new studies were published in Japan and important evidence surfaced in the United States. [11] The majority of research subjects were Chinese, but many were of different nationalities.[1]. [116], As above, during the United States occupation of Japan, the members of Unit731 and the members of other experimental units were allowed to go free. Williams, Peter, and Wallace, David (1989). To study the effects of untreated venereal diseases, male and female prisoners were deliberately infected with syphilis and gonorrhea, then studied. [113] The lead prosecuting attorney at the Khabarovsk trial was Lev Smirnov, who had been one of the top Soviet prosecutors at the Nuremberg Trials. 431968pp. [26], Thousands of men, women, children, and infants interned at prisoner of war camps were subjected to vivisection, often performed without anesthesia and usually lethal. Witnesses to the raid recall a fine reddish dust settling on surfaces all over town, followed by a rash of painful flea bites that afflicted nearly everyone. Unit member Naeo Ikeda wrote: In my experience, when A type blood 100 cc was transfused to an O type subject, whose pulse was 87 per minute and temperature was 35.4 degrees C, 30 minutes later the temperature rose to 38.6 degrees with slight trepidation. This was all in a day's work for the surgeons, but it really left an impression on me because it was my first time. Ministries in Tokyo ordered the destruction of all incriminating materials, including those in Pingfang. Ultimately, inadequate scientific and engineering foundations limited the effectiveness of the Japanese program. So he and another unit member took the keys to the cells and opened one that housed a Chinese woman. ; Japan Confronting Gruesome War Atrocity", "Where To Find The World's Most 'Wicked Bugs': Fleas", "Electrocuted, gassed, frozen, boiled alive", "Inside Japan's wartime factory of death", "Self Determination by Imperial Japanese Doctors", "(RARE) Yoshimura Hisato (excerpt of a telephone interview conducted by Mainichi Shimbun)", "[IAB8] Imperial Japanese Medical Atrocities", https://www.laguardia.edu/maus/files/ethics-ch-16.pdf, https://www.esquiremag.ph/long-reads/features/vivisection-japan-philippines-a00304-20200723-lfrm, "Japanese Medical Atrocities in World War II", " 36 150 . A large area of scratches on his chest were bleeding. [88] One of the prisons housed women and children (Building8), while the other prison housed men (Building7). Human targets were used to test grenades positioned at various distances and in various positions. A report on the Japanese use of plague-infected fleas on Changde was made widely available the following year but was not addressed by the Allied Powers until Franklin D. Roosevelt issued a public warning in 1943 condemning the attacks. Operations and experiments continued until the end of the war. The Russian lying on the floor suddenly sprang up and knocked the guard down. A Unit 731 doctor operates on a patient that is part of a bacteriological experiment. "[33], Unit731 and its affiliated units (Unit 1644 and Unit 100, among others) were involved in research, development and experimental deployment of epidemic-creating biowarfare weapons in assaults against the Chinese populace (both military and civilian) throughout World WarII. Some of the tests have been described as "psychopathically sadistic, with no conceivable military application". It is suspected that the children of female prisoners were killed after birth or aborted.[68]. And as the concept of consent went out the window, so did the restraint of the researchers. Prime Minister Junichiro Koizumi responded that the Japanese government did not then possess any records related to Unit731, but recognized the gravity of the matter and would publicize any records located in the future. [72], At least 3,000 men, women, and children[3]:117[71]from which at least 600 every year were provided by the Kenpeitai[73]were subjected to Unit731 experimentation conducted at the Pingfang camp alone, not including victims from other medical experimentation sites such as Unit 100. Unit 731: The horrors of biological warfare experiments that the world forgot. November 1940. Tamura recalled: Sud had, a few days previously, been interested in talking about women, but now he was thin as a rake, with many purple spots over his body. Two Russian male prisoners were in a cell with handcuffs on, one of them lay flat on the floor pretending to be sick. Even if they had managed to escape the quadrangle (itself a heavily fortified building full of staff), they would have had to get over a three-meter-high (9.8ft) brick wall surrounding the complex, and then across a dry moat filled with electrified wire running around the perimeter of the complex (which can be seen in aerial pictures of the Unit).[97]. The opening of the new Museum of War Crime Evidence by Japanese Army Unit 731 on Aug. 15 in Harbin in northeast China was timed to coincide with the 70th anniversary of Japan's surrender in World War II, part of commemorations across China that included a major Victory Day military parade in Beijing on Sept. 3. Ishii had proposed the creation of a Japanese biological and chemical research unit in 1930, after a two-year study trip abroad, on the grounds that Western powers were developing their own programs. Infected food supplies and clothing were dropped by airplane into areas of China not occupied by Japanese forces. On October 4, 1940, Japanese bombers deployed these casings, each loaded with 30,000 fleas that had each sucked blood from a dying prisoner, over the Chinese village of Quzhou. all the Japanese scientists immunity from war crimes prosecution in exchange for the germ warfare data gathered from experiments in Harbin. Members of Unit 731 were not immune from being subjects of experiments. He then received authorization to move to Pingfang, approximately 24 kilometers (15mi) south of Harbin, to set up a new, much larger facility. Presiding judge Koji Iwata ruled that Unit731, on the orders of the Imperial Japanese Army headquarters, used bacteriological weapons on Chinese civilians between 1940 and 1942, spreading diseases, including plague and typhoid, in the cities of Quzhou, Ningbo, and Changde. After the Japanese invasion of China in 1937, sister chemical and biological warfare units were founded in major Chinese cities and were referred to as Epidemic Prevention and Water Supply Units. Xinhua via Getty ImagesUnit 731 researchers conduct bacteriological experiments with captive child subjects in Nongan County of northeast Chinas Jilin Province. The truth is that Japan's Unit 731 committed some of the most heinous war crimes ever. The Japanese doctors and army commanders who had perpetrated the Unit731 experiments received sentences from the Khabarovsk court ranging from 2 to 25years in a Siberian labor camp. In this way, Unit 731 was performing the service of human experimentation for the entire Japanese medical community, in an on-going feedback loop. Since then, much more in depth testimony has been given in Japan. In 1984, Japanese historian Tsuneishi Keiichi translated and published over 4,000 pages of U.S. documents on Japanese biological warfare. Researchers mostly slipped back into civilian life in occupied Japan as if nothing had ever happened, many of them becoming prominent members of university faculty. Study methods in these experiments were barbaric. [27][28] In a video interview, former Unit731 member Okawa Fukumatsu admitted to having vivisected a pregnant woman. Established by Emperor Hirohito in 1936, Unit 731's exact mission varied over the course of its operations, but two main focuses remained constant. None of the Japanese scientists in Unit 731 was ever punished. Unit731 staff included approximately 300 researchers, including doctors and bacteriologists. Unit 731 was a biological and chemical weapons research and development unit of the Japanese Army. Guards would hold him while another guard would smash the victim's head open with an ax. [16] It was divided at that time into the "Ishii Unit" and "Wakamatsu Unit", with a base in Hsinking. Sanders' duty was to investigate Japanese biological warfare activity. The Unit 731 complex. That was just playing around. Five subjects were forced to drink a solution of yperite and lewisite gas in water, with or without decontamination. When AB type blood 120 cc was transfused to an O type subject, an hour later the subject described malaise and psychroesthesia in both legs. He stated that there were at least over 10,000 victims of internal experiments at the Unit and that he himself vivisected thousands.
