Unit 731 was a Japanese prison camp where grizzly experiments were performed on human subjects, including men, women, and children, during the Second Sino-Japanese War and WW2. Most of the experiments were done on Koreans and Chinese.
* Human targets were used to test grenades positioned at various distances and in different positions.[11] Flame throwers were tested on humans.
* To study the effects of untreated venereal diseases, male and female prisoners were deliberately infected with syphilis and gonorrhea, then studied[11]. Prisoners were infested with fleas in order to acquire large quantities of disease-carrying fleas for the purposes of studying the viability of germ warfare
* Prisoners were subjected to other torturous experiments such as being hung upside down to see how long it would take for them to choke to death, having air injected into their arteries to determine the time until the onset of embolism, and having horse urine injected into their kidneys.
* being placed into centrifuges and spun until dead, having animal blood injected and the effects studied, being exposed to lethal doses of x-rays, having various chemical weapons tested on prisoners inside gas chambers, being injected with sea water to determine if it could be a substitute for saline and being buried alive.
* Vivisections were also performed on pregnant women, sometimes impregnated by doctors, and the fetus removed.[16] Prisoners had limbs amputated in order to study blood loss.[11] Those limbs that were removed were sometimes re-attached to the opposite sides of the body.[11] Some prisoners' limbs were frozen and amputated, while others had limbs frozen then thawed to study the effects of the resultant untreated gangrene and rotting.
Some prisoners had their stomachs surgically removed and the esophagus reattached to the intestines.[11] Parts of the brain, lungs, liver, etc. were removed from some prisoners.
Following the Wikipedia link to
vivisection shows a more complete picture:
* Prisoners of war were subjected to vivisection without anesthesia.[12]
* Vivisections were performed on prisoners after infecting them with various diseases. Scientists performed invasive surgery on prisoners, removing organs to study the effects of disease on the human body. These were conducted while the patients were alive because it was feared that the decomposition process would affect the results.[13] The infected and vivisected prisoners included men, women, children, and infants.[14]
* Vivisections were also performed on pregnant women, sometimes impregnated by doctors, and the fetus removed.[15]
* Some prisoners' limbs were frozen and amputated, while others had limbs frozen then thawed to study the effects of the resultant untreated gangrene and rotting.
* Prisoners had limbs amputated in order to study blood loss.[16]
* Some prisoners had their stomachs surgically removed and the esophagus reattached to the intestines.[16]
* Parts of the brain, lungs, liver, etc. were removed from some prisoners.
Other joys of this place included tossing babies in the air and shooting them, like skeet shooting.
Ultimately, the Japanese dropped infected fleas, clothes, and other dirty chemicals on mainland China, infecting the Chinese with bubonic plague, cholera, etc.

The Horror of Unit 731
Unit 731 is now a war museum. The Japanese are fairly honest about what happened during that time. But alas, there are still deniers that this stuff really took place. I guess that some people simply cannot accept that people can do such harm.
