Yoshimura Hisato, a physiologist assigned to Unit 731, took a special interest in hypothermia. As part of Maruta’s 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. According to one eyewitness accoun...
Unit 731 started out as a research unit, investigating the effects of disease and injury on the fighting ability of an armed force. 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. At first, these patients were vo...
The effectiveness of various weapons was of obvious interest to the Japanese Army. 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. Wound patterns and penetration depths were...
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. To learn what they needed to know, doctors assigned to Unit 731 infected victims with the disease and withheld treatment to observe the uninterrupted ...

After being infected with various diseases, exposed to chemical weapons, or suffering crush injuries, bullet w...

To this end, Unit 731 cycled through tens of thousands of captives at several facilities across Manchu...
