Human Experimentation at Unit 731

Overview

• Unit 731 was a covert biological and chemical warfare research and development unit of the Imperial Japanese Army during World War II.
• Located in Pingfang, China, it is notorious for conducting inhumane experiments on humans, referred to as "marutas" or "logs."
• Estimated 3,000 to 12,000 deaths occurred due to these experiments.

Key Experiments

Frostbite Testing

• Conducted by physiologist Yoshimura Hisato.
• Prisoners' limbs were submerged in icy water until frozen, then tested for thawing techniques using hot water, open flames, or natural thawing.
• Found that the best treatment was water between 100-122 degrees Fahrenheit.

Vivisection

• Performed on conscious prisoners without anesthesia to study living systems.
• Included infected subjects with diseases like cholera and plague to study effects on organs.
• Methods included amputation, reattachment of limbs, and other brutal procedures.

Weapon Testing

• Involved testing bayonets, swords, knives, flamethrowers, blister agents, and nerve gases on prisoners.
• Prolonged X-ray exposure tests led to sterilization and death.

Venereal Disease Studies

• Focused on syphilis.
• Male prisoners were ordered to rape others to study disease transmission and progression.

Human Limits Testing

• Experiments on survival without food/water, crash injuries, and effects of high G-forces.
• Human subjects were spun in centrifuges until they lost consciousness or died.

Rape and Forced Pregnancy

• Female prisoners were impregnated for experimentation on trauma, disease effects, and weapon impacts on fetuses.
• Special interest in syphilis effects on pregnant women.
