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. However, conducting experiments without being bounded by ethical laws was appealing to most Japanese scientists. Established by Emperor Hirohito in 1936, Unit 731's exact mission varied over the course of its operations, but two main focuses remained constant. [132], In October2003, a member of Japan's House of Representatives filed an inquiry.

Since then, much more in depth testimony has been given in Japan. In fact, Japan arguably started the war by attacking Manchuria in 1931, and it inarguably waged war with China by invading in 1937. [6] The United States covered up the human experimentations and handed stipends to the perpetrators. This Russian was shot to death. [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. 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. government.

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. Unit 731 started out as a research unit, investigating the effects of disease and injury on the fighting ability of an armed force. Technician Naokata Ishibashi interacted with two female prisoners. Sanders' duty was to investigate Japanese biological warfare activity. [29] Vivisections were performed on prisoners after infecting them with various diseases. [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. A Unit 731 doctor operates on a patient that is part of a bacteriological experiment. It routinely conducted tests on people who were dehumanized and internally referred to as "logs". Unit 731 researchers conduct bacteriological experiments with captive child subjects in Nongan County of northeast Chinas Jilin Province. Its true purpose was masked as the Epidemic Prevention Research Laboratory.

The design of the facilities made them hard to destroy by bombing. 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. At death, the corpses would only weigh 1/5 normal bodyweight.". 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. Some of Unit731's satellite (branch) facilities are still in use by various Chinese industrial companies. 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 . 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." These bold ones were shot". [6], One graduate of Unit 1644, Masami Kitaoka, continued to perform experiments on unwilling Japanese subjects from 1947 to 1956. Unit731 tested many different chemical agents on prisoners and had a building dedicated to gas experiments. The report describes conditions of every subject precisely without mentioning what happened to them in the long run. He performed his experiments while he was working for Japan's National Institute of Health Sciences. 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. A glass-walled chamber about three meters square [97sqft] and two meters [6.6ft] high was used.

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. I sanitised his whole body with disinfectant. To study the effects of untreated venereal diseases, male and female prisoners were deliberately infected with syphilis and gonorrhea, then studied. 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. [88] One of the prisons housed women and children (Building8), while the other prison housed men (Building7). Low morale. [126], In 2018, Japan disclosed the names of 3,607 members of Unit 731. They show what humans are capable of when they are given free rein to experiment on other human beings. [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. [63] Although this article drew criticism, Yoshimura denied any guilt when contacted by a reporter from the Mainichi Shimbun. The complex contained various factories. November 1940. 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. [29], According to A. S. Wells, the majority of victims were Chinese,[31] with a lesser percentage being Russian, Mongolian, and Korean. 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. [93] The inner-prison was a highly secured building complete with cast iron doors. [4] Japanese researchers performed tests on prisoners with bubonic plague, cholera, smallpox, botulism, and other diseases. There is at least one recorded instance of "friendly" social interaction between prisoners and Unit731 staff. Date unspecified. ][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. Other articles where Unit 731 is discussed: World War II: The horror of war in pictures: Unit 731 of the Imperial Japanese Army carried out horrific medical experiments on thousands of prisoners of war and civilians; men and women were subjected to chemical and biological agents and vivisected to survey the results. Two Russian male prisoners were in a cell with handcuffs on, one of them lay flat on the floor pretending to be sick. 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.

One member of Unit 731 later recalled that very sick and unresisting captives would be laid out on the slab so a line could be inserted into their carotid artery. Sanders was a highly regarded microbiologist and a member of America's military center for biological weapons. Warning: Child-related post. Mucous and bloody erosions across the shoulder girdle. His brain would be extracted off to the pathologist, and then to the crematorium for the usual disposal. [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. [84], No one who entered Unit731 came out alive. September 9, 1940, 7 am: Tired and exhausted. Unit731 also performed transfusion experiments with different blood types. 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. 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. 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. Covered with millet-seed-size to bean-size blisters. 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.

However, Unit 731 was likely the largest biological-warfare production facility in world history. In response, in February2011 the Ministry of Health began to excavate the site. Despite innocent beginnings as a research and public health agency, Unit 731 eventually grew into an assembly line for weaponized diseases that, if fully deployed, could have killed everyone on Earth several times over. It is suspected that the children of female prisoners were killed after birth or aborted.[68]. Some of the tests have been described as "psychopathically sadistic, with no conceivable military application". 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. According to one eyewitness account, the limbs made a sound like a plank of wood when struck with a cane. 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. Unit 731: The horrors of biological warfare experiments that the world forgot. [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". In addition, gas chambers were set up at unit facilities and test subjects exposed to nerve gas and blister agents. One of the unit members raped her; the other member took the keys and opened another cell. 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. September 1937.
