Ministries in Tokyo ordered the destruction of all incriminating materials, including those in Pingfang. Weeping redness of the skin of the upper part of the body. The ministry backed down after new studies were published in Japan and important evidence surfaced in the United States. These bacteria were injected into subjects regularly, and the resulting infections were studied. These experiments also showed how easily we can rationalize these kinds of actions if we believe that we are doing it for the greater good. 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. This term originated as a joke on the part of the staff because the official cover story for the facility given to local authorities was that it was a lumber mill. None of the Chinese, Mongolian, Korean, or Russian captives assigned to Unit 731 survived their confinement. Unit 731 was split into eight divisions. However, the amount of effort devoted to BW was not matched by its results. Operations and experiments continued until the end of the war. 1341361982pp. 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 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. And as the concept of consent went out the window, so did the restraint of the researchers. Japan Confronting Gruesome War Atrocity", "Dissect them alive: order not to be disobeyed", "(RARE) Unit 731 surgeon Okawa Fukumatsu (interview footage)", "Interview with former Unit 731 member Nobuo Kamada", "Vivisectionist recalls his day of reckoning", "Unmasking Horror -- A special report. Unit 731 (Japanese: 731, Hepburn: Nana-san-ichi Butai), short for Manshu Detachment 731 and also known as the Kamo Detachment: 198 and the Ishii Unit, 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 . "It was said that a small number of these poor men, women, and children who became marutas were also mummified alive in total dehydration experiments. Corporal Kikuchi Norimitsu testified that he was told by another unit member that a prisoner "had shown violence and had struck the experimenter with a door handle" and then "jumped out of the cell and ran down the corridor, seized the keys and opened the iron doors and some of the cells. Prisoners were also repeatedly subjected to rape by guards. November 1940. 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. [4] Japanese researchers performed tests on prisoners with bubonic plague, cholera, smallpox, botulism, and other diseases. Bayonets, swords, and knives were also studied in this way, though the victims were usually bound for these tests. There were also twelve members who were formally tried and sentenced in the Khabarovsk War Crime Trials. One of the unit members raped her; the other member took the keys and opened another cell. Unit 731 was one of six human experimentation sites financially supported by the Imperial Japanese government during the Second World War. Unit 731 researchers conduct bacteriological experiments with captive child subjects in Nongan County of northeast Chinas Jilin Province. [129][130] Sabur Ienaga's New History of Japan included a detailed description, based on officers' testimony. Infected food supplies and clothing were dropped by airplane into areas of China not occupied by Japanese forces. [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. [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". To this day, Japan has not apologized for, and China has not forgiven, the countless atrocities Japanese forces visited upon China between 1931 and 1945. 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. In addition to the experimentation in Manchukuo, the Japanese ran human experimentation units all over, such as Unit Ei 1644 in Nanjing and Unit 2646 in inner Mongolia. Their deteriorating health was recorded. Date unspecified. With the coming of the Red Army in August1945, the unit had to abandon their work in haste. and died with this last word. 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. Listen above to the History Uncovered podcast, episode 51: Unit 731, also available on. 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. 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. 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. After being infected with various diseases, exposed to chemical weapons, or suffering crush injuries, bullet wounds, and shrapnel injuries, the pregnant subjects were opened up and the effects on the fetuses studied. [32] Yuasa said that when he performed vivisections on captives, they were "all for practice rather than for research", and that such practises were "routine" among Japanese doctors stationed in China during the war.[21]. Parts of organs, such as the brain, lungs, and liver, were removed from others. Human experimentation at Unit 731 was a well-known secret within the Japanese research community. 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. World War II devastated the lives of more than 100 million people around the world. One one occasion, he demanded a human brain to experiment on, so guards grabbed a prisoner and held him down while one of them hacked. Some were forced to wear various types of gas masks; others wore military uniforms, and some wore no clothes at all. 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. Limbs removed were sometimes reattached to the opposite side of victims' bodies. It was around this time that Unit 731 began referring to confined research subjects as logs, or Maruta in Japanese. A prisoner would be taken from his cell. The purpose of these tests was to determine the amount of water in an individual's body and to see how long one could survive with a very low to no water intake. Members of the Unit referred to Yoshimura as a "scientific devil" and a "cold-blooded animal" because he would conduct his work with strictness. Subjects had limbs amputated and reattached to the other side of the body, while others had their limbs crushed or frozen, or had the circulation cut off to observe the progress of gangrene. Beyond just the syphilis experiments, rape became a common feature of Unit 731s experiments. 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. [56] Wano guessed that the man was Russian because there were many Russians living in the area at that time.[56]. Its records were mostly burned, destroying any useful information the team had managed to generate in 13 years of research. The gruesome professionalism of Unit 731 included a touch of sardonic humor. November 1940. September 8, 1940, 6 am: Neck, breast, upper abdomen and scrotum weeping, The subject was not pursued further by Sutton, who was probably unaware of Unit731's activities. Some were also vivisected. September 1937. 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. At that time we understood in our hearts that justice was not on our side". [34][35]:xii,173. At least 12 large-scale bioweapon field trials were carried out, and at least 11 Chinese cities attacked with biological agents. 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. [112] Whereas the perpetrators of Unit 731 were exempt from prosecution, the U.S. held a tribunal in Yokohama in 1948 that indicted nine Japanese physician professors and medical students for conducting vivisection upon captured American pilots; two professors were sentenced to death and others to 1520 years' imprisonment.[112]. A male and female, one infected with syphilis, would be brought together in a cell and forced into sex with each other. But then finally he stopped. Low morale. Proteinuria. One of the most common experiments at Unit 731 was the vivisection of diseased bodies. September 8, 6 pm: Tired and exhausted. Some prisoners, including Russian and Chinese, were frantically roaming the corridors and kept yelling and shouting. [7][8] On 28 August 2002, Tokyo District Court ruled that Japan had committed biological warfare in China and consequently had slaughtered many residents. As explained in an internal War Department memorandum, dated June 23, 1947: "Since it is believed that the USSR possesses only a small . Professional people, too, like to play. 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. 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. MacArthur struck a deal with Japanese informants:[108] he secretly granted immunity to the physicians of Unit731, including their leader, in exchange for providing America, but not the other wartime allies, with their research on biological warfare and data from human experimentation. More than ten doctors and technicians were present. That guard would then telephone to the "Special Team" in the inner-prison (Shiro Ishii's brother was head of this Special Team). Takashi Tsuchiya. Unit 731 (731), based in the Pingfang district of Harbin and led by the infamous Japanese microbiologist Shiro Ishii, was a covert biological warfare research and development unit of the Imperial Japanese Army that undertook human experimentation during the Second Sino-Japanese War (1937-1945) and World War II. In addition, gas chambers were set up at unit facilities and test subjects exposed to nerve gas and blister agents. 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. All of these units comprised Ishii's network, which, at its height in 1939, oversaw over 10,000 personnel. According to American historian Sheldon H. Harris: The Togo Unit employed gruesome tactics to secure specimens of select body organs. [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. Ishii organized a secret research group, the "Tg Unit", for chemical and biological experimentation in Manchuria. This took place in August1946 and was instigated by David Sutton, assistant to the Chinese prosecutor. 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. 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. But then finally he stopped. Genitals of female prisoners that were infected with syphilis were called "jam-filled buns" by guards.[68]. Plague-infected fleas, bred in the laboratories of Unit731 and Unit1644, were spread by low-flying airplanes over Chinese cities, including coastal Ningbo and Changde, Hunan Province, in 1940 and 1941. As the last witnesses to this history grow old and die, its possible that the matter will never be addressed again. Japanese discussions of Unit731's activity began in the 1950s, after the end of the American occupation of Japan. After Sud's body was carefully checked [by the surgeon], I handed a scalpel to [the surgeon] who, reversely gripping the scalpel, touched Sud's stomach skin and sliced downward. [127] The Japanese government hesitantly acknowledged the unit's existence in the late 1990s, but has refused to discuss its activities. He painfully cried and breathed with difficulty. The tales of World War II are replete with innumerable accounts . [124][125] Harris speculates that US scientists generally wanted to acquire it due to the concept of forbidden fruit, believing that lawful and ethical prohibitions could affect the outcomes of their research. Xinhua via Getty ImagesJapanese personnel in protective suits carry a stretcher through Yiwu, China during Unit 731s germ warfare tests. [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. Epidemics broke out shortly after, to the elation of many researchers, who concluded that paratyphoid fever was "the most effective" of the pathogens. [95] Seiichi Morimura in his book The Devil's Feast went into some greater detail regarding this escape attempt. "The Imperial Japanese Experiments in China". This got the attention of a staff member who saw it as an unusual condition. [17], His younger brother, Prince Mikasa, toured the Unit 731 headquarters in China, and wrote in his memoir that he watched films showing how Chinese prisoners were "made to march on the plains of Manchuria for poison gas experiments on humans. The United States refused to acknowledge the trials, branding them communist propaganda. I cut him open from the chest to the stomach, and he screamed terribly, and his face was all twisted in agony. Millions of inhumane experiments occurred in this research center. Unit 731 was a Japanese biological warfare research unit that operated during WWII. November 1940. 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. Inmates of these facilities were infected with several of the most lethal pathogens known to science, such as Yersinia pestis, which causes bubonic and pneumonic plague, and typhus, which the Japanese hoped would spread from person to person after being deployed and depopulate disputed areas. These books purported to reveal the "true" operations of Unit731, but falsely attributed unrelated photos to the Unit, which raised questions about their accuracy. In 2006, Toyo Ishiia nurse who worked at the school during the warrevealed that she had helped bury bodies and pieces of bodies on the school's grounds shortly after Japan's surrender in 1945. Some of the prisoners managed to jump out but these were only the bold ones. While male prisoners were often used in single studies, so that the results of the experimentation on them would not be clouded by other variables, women were sometimes used in bacteriological or physiological experiments, sex experiments, and as the victims of sex crimes. In addition, poisoned food and candy were given to unsuspecting victims. The occupying US government undertook the cover-up of Japanese war crimes after the end of World War II, granting political immunity to military personnel who had engaged in human experimentation and other crimes against humanity, predominantly in mainland China. Unit 731 started out as a research unit, investigating the effects of disease and injury on the fighting ability of an armed force. Researchers performed invasive surgery on prisoners, removing organs to study the effects of disease on the human body. [84], No one who entered Unit731 came out alive. But before Unit 731 was broken up in 1945, it committed some of the most torturous human experiments in recorded history. Other sources suggest that it was the usual practice in the Unit for surgeons to stuff a rag (or medical gauze) into the mouth of prisoners before commencing vivisection in order to stifle any screaming. While they have added over 60,000names to the watchlist, they have only been able to identify under 100 Japanese participants. Its head was Lieutenant Shiro Ishii. Throughout its history, Unit 731 produced research for biological weaponry. September 1937. In this way, Unit 731 was performing the service of human experimentation for the entire Japanese medical community, in an on-going feedback loop. The hypothetical possibility of vertical transmission (from mother to child) of diseases, particularly syphilis, was the stated reason for the torture. [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. When the plague bacillus had been bred to what was felt to be a sufficiently lethal caliber, the last generation of victims to be infected were exposed to huge numbers of fleas, Y. pestis preferred vector of contagion. One of the most heinous types of experiments conducted in Unit 731 was . Unit 731: The horrors of biological warfare experiments that the world forgot. Approximately 30 kilograms (66lb) of bubonic plague bacteria could be produced in a few days. A glass-walled chamber about three meters square [97sqft] and two meters [6.6ft] high was used. 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. A Unit 731 doctor operates on a patient that is part of a bacteriological experiment. These bold ones were shot". [20] In a further parallel, the corpses of "sacrificed" subjects were disposed of by incineration. Looks with hollow eyes.

[29] Vivisections were performed on prisoners after infecting them with various diseases. [94], Despite the prison's status as a highly secure building, at least one unsuccessful escape attempt did occur. 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. [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. 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. First, the Imperial Army of Japan wanted to. Flamethrowers were also tested, on both covered and exposed skin. They spanned all the way to Singapore, as well, with Unit 9420.Unit 731 was just one out of several, but it became infamous once the extent and variety of its atrocities became known to the public. 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. [59] The following is an excerpt of one of these reports: September 7, 1940, 6 pm: Tired and exhausted. 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 totality of Unit 731s research was in support of their larger mission, which by 1939 was to develop horrific weapons of mass destruction for use against the Chinese population, and presumably American and Soviet forces, if the time ever came. [107] Sanders took this information to General Douglas MacArthur, who was the Supreme Commander of the Allied Powers and responsible for rebuilding Japan during the Allied occupations. [11] They viewed the Chinese as no cost research subjects, and hoped that they could use this advantage to lead the world in biological warfare. reddened, swollen. Most or all Units had branch offices, which were also often referred to as "Units". Body temperature 37 degrees Celsius. Unit100 also experimented with toxic gas. "[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. [81] Sheldon H. Harris documented that the victims were generally political dissidents, communist sympathizers, ordinary criminals, impoverished civilians, and the mentally disabled. Hisato then tried different methods for rapid rewarming of the frozen appendage. Since then, much more in depth testimony has been given in Japan. [15], In 1936, Emperor Hirohito issued a decree authorizing the expansion of the unit and its integration into the Kwantung Army as the Epidemic Prevention Department. The Japanese unit 731 experiments are a dark part of our history. [6], One graduate of Unit 1644, Masami Kitaoka, continued to perform experiments on unwilling Japanese subjects from 1947 to 1956. There is such a thing as professional curiosity: What would happen if we did such and such? What medical purpose was served by performing and studying beheadings? Ishii had wanted to use biological weapons in the Pacific War since May1944, but his attempts were repeatedly snubbed. 1936-1945: Unit 731 the Asian Auschwitz was a massive biological warfare research program of the Japanese Imperial Army under the command of Lt. General Dr. Ishii Shiro in Pin Fang, Manchuria outside the city of Harbin. 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. [30], Prisoners had limbs amputated in order to study blood loss. The Japanese defense counsel argued that the claim was vague and uncorroborated and it was dismissed by the tribunal president, Sir William Webb, for lack of evidence. . [128], Japanese history textbooks usually contain references to Unit731, but do not go into detail about allegations, in accordance with this principle.

It was surgery for most, autopsies for the rest. Meanwhile, prolonged X-ray exposure sterilized and killed thousands of research participants, as well as inflicting horrible burns when the emitting plates were miscalibrated or held too close to the subjects nipples, genitals, or faces. 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."

Some of Unit731's satellite (branch) facilities are still in use by various Chinese industrial companies. Located in the Pingfang district of what is now China, most of . [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. all the Japanese scientists immunity from war crimes prosecution in exchange for the germ warfare data gathered from experiments in Harbin. One group was clothed with Chinese underwear, no hat, and no mask and was subjected to as much as 1,800 field gun rounds of yperite gas over 25minutes. Xinhua via Getty ImagesA Unit 731 doctor operates on a patient that is part of a bacteriological experiment. Study methods in these experiments were barbaric. [63] Although this article drew criticism, Yoshimura denied any guilt when contacted by a reporter from the Mainichi Shimbun. One prisoner was a 21-year-old Chinese woman, the other a Soviet girl who was 19years of age. Unit 731 is a biological warfare organ of the Imperial Japanese Army, which conducted horrific human experiments on prisoners of war and civilians in northeast China during WWII. As stated above, dehydration experiments were performed on the victims. [35]:xii,173 The American historian Sheldon H. Harris states that over 200,000 died. All under the auspices of the US govt, ofc. [133] In April2018, the National Archives of Japan released the names of 3,607members of Unit731, in response to a request by Professor Katsuo Nishiyama of the Shiga University of Medical Science.[134][135]. Flamethrowers were tested on people. [1] Japan's occupation of Manchuria began in 1931 after the Japanese invasion of Manchuria. Eyelids and conjunctivae hyperemic and edematous. [86] No one could enter without special permits and an ID pass with a photograph, and the entry/exit times were recorded.
