[96] One staff member, who was an eyewitness at this escape attempt, recalled: "spiritually we were all lost in front of the 'marutas' who had no freedom and no weapons. [93] The inner-prison was a highly secured building complete with cast iron doors. [1] The Americans co-opted the researchers' bioweapons information and experience for use in their own biological warfare program, much like what had been done with Nazi German researchers in Operation Paperclip. 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. The ministry backed down after new studies were published in Japan and important evidence surfaced in the United States. To ensure effective transmission of the disease, syphilitic male victims were ordered to rape both female and male fellow captives, who would then be monitored to observe the onset of the disease. 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. The author Seiichi Morimura published The Devil's Gluttony[ja] () in 1981, followed by The Devil's Gluttony: A Sequel in 1983. He made this unimaginable sound, he was screaming so horribly. [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. 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. Whenever he moved, a rope around his neck tightened. November 1940. Mucous and bloody diarrhea. A Youth Corps member deployed to train at Unit731 recalled viewing a batch of subjects that would undergo syphilis testing: "one was a Chinese woman holding an infant, one was a White Russian woman with a daughter of four or five years of age, and the last was a White Russian woman with a boy of about six or seven. So he and another unit member took the keys to the cells and opened one that housed a Chinese woman. Operations and experiments continued until the end of the war. It was made clear that anyone resisting would be shot. [84], No one who entered Unit731 came out alive. [68] Until Sanders finally threatened the Japanese with bringing the Soviets into the picture, little information about biological warfare was being shared with the Americans. Ultimately, inadequate scientific and engineering foundations limited the effectiveness of the Japanese program. Unit 731 was a Japanese biological warfare research unit that operated during WWII. To determine the best course of treatment for varying degrees of shrapnel wounds sustained on the field by Japanese Soldiers, Chinese prisoners were exposed to direct bomb blasts. [30], Prisoners had limbs amputated in order to study blood loss. At the time of his arrival in Japan, he had no knowledge of what Unit731 was. As explained in an internal War Department memorandum, dated June 23, 1947: "Since it is believed that the USSR possesses only a small . [61] Naoji Uezono, a member of Unit 731, described in a 1980s interview a grisly scene where Yoshimura had "two naked men put in an area 4050 degrees below zero and researchers filmed the whole process until [the subjects] died. . [39], Due to pressure from numerous accounts of the biowarfare attacks, Chiang Kai-shek sent a delegation of army and foreign medical personnel in November1941 to document evidence and treat the afflicted. There is at least one recorded instance of "friendly" social interaction between prisoners and Unit731 staff. Its records were mostly burned, destroying any useful information the team had managed to generate in 13 years of research. The two Russians opened their handcuffs, took the keys, and opened some other cells while yelling. September 1937. June 1942. rape became a common feature of Unit 731s experiments, infected with several of the most lethal pathogens known to science, Japan likewise planned to bomb America with plague-ridden fleas, Nazi research actually contributed anything to medical science. Unit 731 started out as a research unit, investigating the effects of disease and injury on the fighting ability of an armed force. From 1948 to 1958, less than five percent of the documents were transferred onto microfilm and stored in the US National Archives before they were shipped back to Japan.[118]. He was about to rape her anyway, then he saw that her sex organ was festering, with pus oozing to the surface. An expedition to Nanjing involved spreading typhoid and paratyphoid germs into the wells, marshes, and houses of the city, as well as infusing them in snacks distributed to locals. Listen above to the History Uncovered podcast, episode 51: Unit 731, also available on Apple and Spotify. A former member of the Special Team (who insisted on anonymity) recalled in 1995 his first vivisection conducted at the Unit: He didn't struggle when they led him into the room and tied him down. A Unit 731 doctor operates on a patient that is part of a bacteriological experiment.

Unit 731 was a biological and chemical weapons research and development unit of the Japanese Army. For example, female captives of childbearing age were sometimes forcibly impregnated so that weapon and trauma experiments could be done on them. And as the concept of consent went out the window, so did the restraint of the researchers. In 1952, human experiments carried out in Nagoya City Pediatric Hospital, which resulted in one death, were publicly tied to former members of Unit731. For example, one experiment documented the time it took for three-day-old babies to freeze to death.[57][58]. David C. Rapoport. 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. [132], In October2003, a member of Japan's House of Representatives filed an inquiry. It had around 4,500containers to be used to raise fleas, six cauldrons to produce various chemicals, and around 1,800containers to produce biological agents. A large area of scratches on his chest were bleeding. All of these units comprised Ishii's network, which, at its height in 1939, oversaw over 10,000 personnel. 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. The main site of Japan's experiments into biological warfare was the prisoner of war camp known as Unit 731 located in Pingfan, Manchuria, where Chinese inmates were subjected to gruesome experiments aimed at testing the limits of the human body and the effectiveness of biological and chemical agents. [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]. Other attacks, using anthrax, killed approximately 6,000 more people in the area. 431968pp. Unit 731 was one of six human experimentation sites financially supported by the Imperial Japanese government during the Second World War. Looks with hollow eyes. And to study the effects of high G-forces on pilots and falling paratroopers, Unit 731 personnel loaded human beings into large centrifuges and spun them at higher and higher speeds until they lost consciousness and/or died, which usually happened around 10 to 15 Gs, though young children showed a lower tolerance for acceleration forces. Sanders was a highly regarded microbiologist and a member of America's military center for biological weapons. Millions of inhumane experiments occurred in this research center. While they have added over 60,000names to the watchlist, they have only been able to identify under 100 Japanese participants. [91] Prisoners were repeatedly reused for experiments as long as they were healthy enough. [56] Ice was then chipped away, with the affected area being subjected to various treatments, such as being doused in water, exposed to the heat of fire, etc. Unit 731 was a biological warfare research division of the Imperial Japanese Army, which was founded in 1936. Victims included not only kidnapped men, women (including pregnant women) and children but also babies born from the systemic rape perpetrated by the staff inside the compound. [18] Medical doctors and professors from Japan were attracted to join Unit731 both by the rare opportunity to conduct human experimentation and the Army's strong financial backing. Unit731 also performed transfusion experiments with different blood types. First, the Imperial Army of Japan wanted to. Ishibashi asked where she came from and learned that she was from Ukraine. 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. Male prisoners infected with syphilis would be told to rape female prisoners as well as male prisoners in order to see how syphilis spreads in the body. Unit 731 (731) led by Japanese microbiologist Shiro Ishii, was a covert biological warfare research and development unit of the Imperial Japanese Army that undertook human experimentation mainly on Chinese, Koreans, and Russians, during the Second Sino-Japanese War (1937-1945) and World War II. The disturbances and upheavals that these invasions caused shook China to its very foundations, triggered a civil war and a famine that probably killed more people than currently live in Canada and Australia combined, and lasted until the countrys Soviet liberation in 1945. Ishii had wanted to use biological weapons in the Pacific War since May1944, but his attempts were repeatedly snubbed. After World WarII, the Office of Special Investigations created a watchlist of suspected Axis collaborators and persecutors who are banned from entering the United States. Takeo Wano, a former medical worker in Unit 731, said that he saw a Western man, who was vertically cut into two pieces, pickled in a jar of formaldehyde. [128], Japanese history textbooks usually contain references to Unit731, but do not go into detail about allegations, in accordance with this principle. [75][76][77] Vivisections were also conducted on native Filipinos in the Philippines. Study methods in these experiments were barbaric. Insisting on anonymity, the former Japanese medical assistant recounted his first experience in dissecting a live human being, who had been deliberately infected with the plague, for the purpose of developing "plague bombs" for war. 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. Xinhua via Getty ImagesUnit 731 personnel conduct a bacteriological trial upon a test subject in Nongan County of northeast Chinas Jilin Province. [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. Human experimentation at Unit 731 was a well-known secret within the Japanese research community. It was around this time that Unit 731 began referring to confined research subjects as logs, or Maruta in Japanese. As the last witnesses to this history grow old and die, its possible that the matter will never be addressed again. [42] The plan was scheduled to launch on 22September 1945, but Japan surrendered five weeks earlier.[43][44][45]. [35]:xii,173 The American historian Sheldon H. Harris states that over 200,000 died. Some were forced to wear various types of gas masks; others wore military uniforms, and some wore no clothes at all. Unit 731 personnel conduct a bacteriological trial upon a test subject in Nongan County of northeast Chinas Jilin Province. Vivisection, for example, is the practice of mutilating human bodies, without anesthesia, to study the operations of living systems. Epiphora. ", Prisoners were injected with diseases, disguised as vaccinations,[25] to study their effects. The Supreme Court of Japan ruled in 1997 that the testimony was indeed sufficient and that requiring it to be removed was an illegal violation of freedom of speech. However, according to a junior uniformed civilian employee of the Imperial Japanese Army working in Unit731, the project was internally called "Holzklotz", German for log. In James M. Ludes, Henry Sokolski (eds.). I cut him open from the chest to the stomach, and he screamed terribly, and his face was all twisted in agony. Originally set up by the Kenpeitai military police of the Empire of Japan, Unit731 was taken over and commanded until the end of the war by General Shir Ishii, a combat medic officer in the Kwantung Army. [127], In 1983, the Japanese Ministry of Education asked Japanese historian Sabur Ienaga to remove a reference from one of his textbooks that stated Unit 731 conducted experiments on thousands of Chinese. It was surgery for most, autopsies for the rest. An attack on Changde in 1941 reportedly led to approximately 10,000 biological casualties and 1,700 deaths among ill-prepared Japanese troops, in most cases due to cholera. Eyelids and conjunctivae hyperemic and edematous. The idea of Unit 731 first circulated around by a memo written in April 23, 1936, that speaks about the establishment of reinforcement military forces in Manchuria. Some prisoners, including Russian and Chinese, were frantically roaming the corridors and kept yelling and shouting. He later testified about the playfulness of the experimenters:[24], Some of the experiments had nothing to do with advancing the capability of germ warfare, or of medicine. Unit 731: The horrors of biological warfare experiments that the world forgot. The prison cells had wooden floors and a squat toilet in each. Army Engineer Hisato Yoshimura conducted experiments by taking captives outside, dipping various appendages into water of varying temperatures, and allowing the limb to freeze. 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. The report describes conditions of every subject precisely without mentioning what happened to them in the long run. [7][8] On 28 August 2002, Tokyo District Court ruled that Japan had committed biological warfare in China and consequently had slaughtered many residents. To study the effects of untreated venereal diseases, male and female prisoners were deliberately infected with syphilis and gonorrhea, then studied. In 1984, Japanese historian Tsuneishi Keiichi translated and published over 4,000 pages of U.S. documents on Japanese biological warfare. 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. In this way, Unit 731 was performing the service of human experimentation for the entire Japanese medical community, in an on-going feedback loop. While he was there, he watched footage of human experiments and executions from Unit731. In a 1998 correspondence letter between the DOJ and Rabbi Abraham Cooper, Eli Rosenbaum, director of OSI, stated that this was due to two factors: There have been several films about the atrocities of Unit 731. However, Unit 731 was likely the largest biological-warfare production facility in world history. Unit 731 was responsible for some of the most notorious war crimes committed by the Japanese armed forces. To learn what they needed to know, doctors assigned to Unit 731 infected victims with the disease and withheld treatment to observe the uninterrupted course of the illness. In response, in February2011 the Ministry of Health began to excavate the site. As stated above, dehydration experiments were performed on the victims. 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. Prisoners were generally well fed on a diet of rice or wheat, meat, fish, and occasionally even alcohol in order to be in normal health at the beginning of experiments. None at all. In addition, poisoned food and candy were given to unsuspecting victims. However, he rejected victims' compensation claims on the grounds that they had already been settled by international peace treaties. He performed his experiments while he was working for Japan's National Institute of Health Sciences. Its head was Lieutenant Shiro Ishii. In one of many records, after a Japanese surgeon fetched a Filipino native from the population and performed vivisection on him, he then removed his appendix and sewed him back up. Finally, when a prisoners body was all used up, they would typically be shot or killed by lethal injection, though some may have been buried alive. November 1940. [9][10], Japan started its biological weapons program in the 1930s, partly because biological weapons were banned by the Geneva Convention of 1925; they reasoned that the ban verified its effectiveness as a weapon. Unit731 staff included approximately 300 researchers, including doctors and bacteriologists. Two Russian male prisoners were in a cell with handcuffs on, one of them lay flat on the floor pretending to be sick. Most Japanese civilian scientists before their time at Unit 731 had never used science in an unethical and malicious way. ; Japan Confronting Gruesome War Atrocity", Centers for Disease Control and Prevention, "Biohazard: Unit 731 and the American Cover-Up", "The 1925 Geneva Protocol: China's CBW Charges Against Japan at the Tokyo War Crimes Tribunal", "Unmasking Horror A special report. [52][53] Massive amounts of blood were drained from some prisoners in order to study the effects of blood loss according to former Unit731 vivisectionist Okawa Fukumatsu. At least 12 large-scale bioweapon field trials were carried out, and at least 11 Chinese cities attacked with biological agents. While most documents captured by the US in Europe were microfilmed before being returned to their respective governments, the Department of Defense decided to not microfilm its vast collection of documents before returning them to the Japanese government.

Unit 731 (Japanese: 731, Hepburn: Nana-san-ichi Butai),[note 1] short for Manshu Detachment731 and also known as the Kamo Detachment[3]:198 and the Ishii Unit,[5] was a covert biological and chemical warfare research and development unit of the Imperial Japanese Army that engaged in lethal human experimentation and biological weapons manufacturing during the Second Sino-Japanese War (19371945) and World War II. Unit731 tested many different chemical agents on prisoners and had a building dedicated to gas experiments. [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, [95] Seiichi Morimura in his book The Devil's Feast went into some greater detail regarding this escape attempt. 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. [60] Once frozen, Yoshimura would strike their affected limbs with a short stick, "emitting a sound resembling that which a board gives when it is struck". These books purported to reveal the "true" operations of Unit731, but falsely attributed unrelated photos to the Unit, which raised questions about their accuracy. At that time we understood in our hearts that justice was not on our side". In fact, Japan arguably started the war by attacking Manchuria in 1931, and it inarguably waged war with China by invading in 1937. That staff member decided to enter the cell. Estimates of the death toll from experiments performed on prisoners at Unit 731 range from 3,000 to 12,000. Five subjects were forced to drink a solution of yperite and lewisite gas in water, with or without decontamination. Date unspecified. Technician Naokata Ishibashi interacted with two female prisoners. Although the dissemination methods of delivering plague infected fleas by aircraft were crude, the method, among others, allowed the Japanese to "conduct the most extensive employment of biological weapons during WWII." Ministries in Tokyo ordered the destruction of all incriminating materials, including those in Pingfang. After this look at Unit 731, read up on some more of the worst war crimes ever committed as well as other Japanese war crimes from the World War II era. These bacteria were injected into subjects regularly, and the resulting infections were studied. [4] Japanese researchers performed tests on prisoners with bubonic plague, cholera, smallpox, botulism, and other diseases. [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. A report authored by unknown researcher in the Kamo Unit (Unit731) describes a large human experiment of yperite gas (mustard gas) on 710September 1940. 541 Likes, 42 Comments - PORTRAITSOUL | Speak Truth (@portraitsoul5.0) on Instagram: ""Unit 731 was responsible for some of the most notorious war crimes committed by the Japanese a." PORTRAITSOUL | Speak Truth on Instagram: ""Unit 731 was responsible for some of the most notorious war crimes committed by the Japanese armed forces. Twenty subjects were divided into three groups and placed in combat emplacements, trenches, gazebos, and observatories. But that didn't stop a Japanese army medical officer named Shiro . September 8, 6 pm: Tired and exhausted. Ishii organized a secret research group, the "Tg Unit", for chemical and biological experimentation in Manchuria. [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. And out of all the atrocities that Imperial Japan unleashed upon the Chinese people during this brutal occupation, probably none were as gratuitously hateful as the operations of Unit 731, the Japanese biological warfare unit that somehow plumbed new depths in what was already a genocidal war. [126], In 2018, Japan disclosed the names of 3,607 members of Unit 731. Sometimes he did this by dousing the limb with hot water, sometimes by holding it close to an open fire, and other times by leaving the subject untreated overnight to see how long it took for the persons own blood to thaw it out.
