The two Russians opened their handcuffs, took the keys, and opened some other cells while yelling. It is suspected that the children of female prisoners were killed after birth or aborted.[68]. Then, have a look at four of the most evil science experiments ever performed and find out whether or not any of the highly disturbing Nazi research actually contributed anything to medical science. Ishii organized a secret research group, the "Tg Unit", for chemical and biological experimentation in Manchuria. This team wore white overall suits, army hats, rubber boots, and pistols strapped to their sides.[86]. Listen above to the History Uncovered podcast, episode 51: Unit 731, also available on Apple and Spotify. Low morale. Once at the inner-prison, technicians would take samples of the prisoners' blood and stool, test their kidney function, and collect other physical data. The testimony of a unit member that served as a guard graphically demonstrated this reality: One of the former researchers I located told me that one day he had a human experiment scheduled, but there was still time to kill. This got the attention of a staff member who saw it as an unusual condition. A Unit 731 doctor operates on a patient that is part of a bacteriological experiment. The Unit731 complex covered six square kilometers (2.3sqmi) and consisted of more than 150buildings. [94], Despite the prison's status as a highly secure building, at least one unsuccessful escape attempt did occur. One Russian shouted to the members of Unit731, demanding to be shot rather than used as an experimental object. It was around this time that Unit 731 began referring to confined research subjects as logs, or Maruta in Japanese. But then finally he stopped. 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. [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. Koizumi had joined a secret poison gas research committee in 1915, during World War I, when he and other Imperial Japanese Army officers were impressed by the successful German use of chlorine gas at the Second Battle of Ypres, in which the Allies suffered 5,000 deaths and 15,000 wounded as a result of the chemical attack. There is at least one recorded instance of "friendly" social interaction between prisoners and Unit731 staff. Among the individuals in Japan after its 1945 surrender was Lieutenant Colonel Murray Sanders, who arrived in Yokohama via the American ship Sturgess in September1945. [115] This was evidenced by the Soviet Union building a biological weapons facility in Sverdlovsk using documentation captured from Unit731 in Manchuria. As part of Marutas study in limb injuries, Hisato routinely submerged captives limbs in a tub of water filled with ice and had them held until the arm or leg had frozen solid and a coat of ice had formed over the skin. If the first exposure failed to establish infection, more rapes would be arranged until it did. Testimony from multiple guards blames the female victims as being hosts of the diseases, even as they were forcibly infected. Additionally, Unit 731 produced biological weapons that were used in areas of China not occupied by Japanese forces, which included Chinese cities and towns, water sources, and fields. Unit731 staff included approximately 300 researchers, including doctors and bacteriologists. Xinhua via Getty ImagesUnit 731 researchers conduct bacteriological experiments with captive child subjects in Nongan County of northeast Chinas Jilin Province. These bold ones were shot". Unit731 also tested chemical weapons on prisoners in field conditions. 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. Some prisoners, including Russian and Chinese, were frantically roaming the corridors and kept yelling and shouting. [91] Prisoners were repeatedly reused for experiments as long as they were healthy enough. Unit731 and the other units of the Epidemic Prevention and Water Purification Department operated biological weapon production, testing, deployment, and storage facilities. It operated covertly for ten years since 1935 in Harbin, China, and was responsible for some of the most notorious war crimes committed by Imperial Japan, due to its extensive use of lethal human experimentation. In unit 731, human targets were used to test grenades positioned at various distances and in various positions. ][65] Yoshimura developed a "resistance index of frostbite" based on the mean temperature 5 to 30minutes after immersion in freezing water, the temperature of the first rise after immersion, and the time until the temperature first rises after immersion. Some prisoners had their stomachs surgically removed and their esophagus reattached to the intestines. Takashi Tsuchiya. Others were deliberately infected with plague bacteria and other microbes. Evil is as evil does. However, Unit 731 was likely the largest biological-warfare production facility in world history. It was surgery for most, autopsies for the rest. Less discussed than the Holocaust forced on Jewish people during World War II, Unit 731 is Japan's covert biological and chemical research division that primarily operated in China between 1932 and 1945. Its true purpose was masked as the Epidemic Prevention Research Laboratory. [30], Prisoners had limbs amputated in order to study blood loss. Date unspecified. One element of the unit, called "Maruta," took this research a little further than the usual bounds of medical ethics by observing injuries and the course of disease on living patients. Ishii ordered every member of the group to disappear and "take the secret to the grave". There are unit members who were known to be interned at the Fushun War Criminals Management Centre and Taiyuan War Criminals Management Centre after the war, who then went on to be repatriated to Japan and founded the Association of Returnees from China and testified about Unit 731 and the crimes perpetrated there. Unit 731 was responsible for some of the most notorious war crimes committed by the Japanese armed forces. [127] The information was from the country's national archives. Most Japanese civilian scientists before their time at Unit 731 had never used science in an unethical and malicious way. Unit 731, Japan's biological warfare program, was formed in 1932 under the leadership of the notorious Gen. Shiro Ishii, chief medical officer of the Japanese army. One of the most common experiments at Unit 731 was the vivisection of diseased bodies. Experiments included disease injections, controlled dehydration, biological weapons testing, vacuum chamber experiments on humans, vivisection, amputation, and standard weapons testing. To breed the most lethal strains possible, doctors monitored patients for rapid onset of symptoms and quick progression. "Terrorism and Weapons of the Apocalypse". Japanese discussions of Unit731's activity began in the 1950s, after the end of the American occupation of Japan. The fleas were then packed in dust and sealed inside clay bomb casings. Bayonets, swords, and knives were also studied in this way, though the victims were usually bound for these tests. [126], In 2018, Japan disclosed the names of 3,607 members of Unit 731. [35]:xii,173 The American historian Sheldon H. Harris states that over 200,000 died. When AB type blood 100 cc was transfused to a B type subject, there seemed to be no side effect. The program received generous support from the Japanese government until the end of the war in 1945. The effectiveness of various weapons was of obvious interest to the Japanese Army. [86][87] Then, the prisoners would be transported through a secret tunnel dug under the facade of the central building to the inner-prisons. 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. He then received authorization to move to Pingfang, approximately 24 kilometers (15mi) south of Harbin, to set up a new, much larger facility. [6], One graduate of Unit 1644, Masami Kitaoka, continued to perform experiments on unwilling Japanese subjects from 1947 to 1956. [29], According to A. S. Wells, the majority of victims were Chinese,[31] with a lesser percentage being Russian, Mongolian, and Korean.

Weapon Test in Unit 731 Experiments It is common to test weapons before going to the war, but it is uncommon to test weapons on living humans. In one case, at least half a liter of blood was drawn at two-to-three-day intervals.[54]. As the war drew to a close in 1945, the Japanese demolished Unit 731 and most of the other research facilities in China to destroy . [123] [122], Japanese Biological Warfare operations were by far the largest during WWII, and "possibly with more people and resources than the BW producing nations of France, Hungary, Italy, Poland, and the Soviet Union combined, between the world wars. The Japanese unit 731 experiments are a dark part of our history. 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. The complex contained various factories. The Japanese wanted to avoid prosecution under the Soviet legal system, so, the morning after he made his threat, Sanders received a manuscript describing Japan's involvement in biological warfare. World War II devastated the lives of more than 100 million people around the world. However, the amount of effort devoted to BW was not matched by its results. None of the Japanese scientists in Unit 731 was ever punished. On 6May 1947, Douglas MacArthur, the Supreme Commander of the Allied Forces, wrote to Washington in order to inform it that "additional data, possibly some statements from Ishii, can probably be obtained by informing Japanese involved that information will be retained in intelligence channels and will not be employed as 'war crimes' evidence". As stated above, dehydration experiments were performed on the victims. Wound patterns and penetration depths were then compared on the bodies of the dead and dying inmates. [132], In October2003, a member of Japan's House of Representatives filed an inquiry. So he and another unit member took the keys to the cells and opened one that housed a Chinese woman.

Approximately 30 kilograms (66lb) of bubonic plague bacteria could be produced in a few days. More than ten doctors and technicians were present. [21] Researchers in Unit731 also published some of their results in peer-reviewed journals, writing as though the research had been conducted on nonhuman primates called "Manchurian monkeys" or "long-tailed monkeys".[22]. Vivisection, for example, is the practice of mutilating human bodies, without anesthesia, to study the operations of living systems. Parts of organs, such as the brain, lungs, and liver, were removed from others. [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. [71] Harris also said plague-infected animals were released near the end of the war, and caused plague outbreaks that killed at least 30,000 people in the Harbin area from 1946 to 1948. Its head was Lieutenant Shiro Ishii. Epiphora. June 1942. They were strapped, unprotected, to wooden planks that were staked into the ground at increasing distances around a bomb that was then detonated. [5] These operations killed tens of thousands with bubonic plague epidemics. [106] Potassium cyanide vials were issued for use in case the remaining personnel were captured. In August 1945, after Hiroshima and Nagasaki had both been bombed, the Soviet Army had invaded Manchuria and utterly annihilated the Japanese Army, and the emperor read his infamous surrender declaration over the radio, Unit 731 was officially disbanded. Later in 1981, one of the last surviving members of the Tokyo Tribunal, Judge Rling, had expressed bitterness in not being made aware of the suppression of evidence of Unit 731 and wrote, "It is a bitter experience for me to be informed now that centrally ordered Japanese war criminality of the most disgusting kind was kept secret from the court by the U.S. Twenty subjects were divided into three groups and placed in combat emplacements, trenches, gazebos, and observatories. Looks with hollow eyes. [69][70] In addition to Chinese casualties, 1,700 Japanese troops in Zhejiang during Zhejiang-Jiangxi campaign were killed by their own biological weapons while attempting to unleash the biological agent, indicating serious issues with distribution. [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. [28] Imperial Japanese Army surgeon Ken Yuasa suggests that practising vivisection on human subjects was widespread even outside Unit731,[31] estimating that at least 1,000 Japanese personnel were involved in the practice in mainland China. Two Russian male prisoners were in a cell with handcuffs on, one of them lay flat on the floor pretending to be sick. Hisato then tried different methods for rapid rewarming of the frozen appendage. This Russian was shot to death. The history of Imperial Japan's human experiments was one in which Ishii and Unit 731 was the principal actor, but Unit 731 operated in a much larger context. Eyelids and conjunctivae hyperemic and edematous. 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. The hypothetical possibility of vertical transmission (from mother to child) of diseases, particularly syphilis, was the stated reason for the torture. Chief of the Personnel Division of the Kwantung Army Headquarters Tamura Tadashi testified that, when he was shown the inner-prison, he looked into the cells and saw living people in chains, some moved around, others were lying on the bare floor and were in a very sick and helpless condition. Sud shouted "brute!" First, the Imperial Army of Japan wanted to. Unit 731 was one of six human experimentation sites financially supported by the Imperial Japanese government during the Second World War. Study methods in these experiments were barbaric. The two prisoners told Ishibashi that they had not seen their faces in a mirror since being captured and begged him to get one.
