Japanese war crimes
The Empire of Japan committed war crimes and crimes against humanity in many Asian-Pacific countries during the period of Japanese imperialism, primarily during the Second Sino-Japanese and Pacific Wars. These incidents have been described as "the Asian Holocaust". Some war crimes were committed by Japanese military personnel during the late 19th century, but most were committed during the first part of the Shōwa era, the name given to the reign of Emperor Hirohito.
Kwantung Army
The Kwantung Army (Japanese: 関東軍, Kantō-gun) was a general army of the Imperial Japanese Army from 1919 to 1945. The Kwantung Army formed in 1906 as a security force for the Kwantung Leased Territory and South Manchurian Railway Zone after the Russo-Japanese War of 1904–1905, and expanded into an army group during the Interwar period to support Japanese interests in China, Manchuria, and Mongolia.
Biological warfare
Biological warfare, also known as germ warfare, is the use of biological toxins or infectious agents such as bacteria, viruses, insects, and fungi with the intent to kill, harm or incapacitate humans, animals or plants as an act of war. Biological weapons (often termed "bio-weapons", "biological threat agents", or "bio-agents") are living organisms or replicating entities (i.e. viruses, which are not universally considered "alive"). Entomological (insect) warfare is a subtype of biological warfare.
Pacific War
The Pacific War, sometimes called the Asia–Pacific War, was the theater of World War II that was fought in eastern Asia, the Pacific Ocean, the Indian Ocean, and Oceania. It was geographically the largest theater of the war, including the vast Pacific Ocean theater, the South West Pacific theater, the Second Sino-Japanese War, and the Soviet–Japanese War. The Second Sino-Japanese War between the Empire of Japan and the Republic of China had been in progress since 7 July 1937, with hostilities dating back to 1931 with the Japanese invasion of Manchuria.
Doolittle Raid
The Doolittle Raid, also known as Doolittle's Raid, as well as the Tokyo Raid, was an air raid on 18 April 1942 by the United States on the Japanese capital Tokyo and other places on Honshu during World War II. It was the first American air operation to strike the Japanese archipelago. Although the raid caused comparatively minor damage, it demonstrated that the Japanese mainland was vulnerable to American air attacks. It served as an initial retaliation for the December 7, 1941 attack on Pearl Harbor, and provided an important boost to American morale.
Human subject research
Human subject research is systematic, scientific investigation that can be either interventional (a "trial") or observational (no "test article") and involves human beings as research subjects, commonly known as test subjects. Human subject research can be either medical (clinical) research or non-medical (e.g., social science) research. Systematic investigation incorporates both the collection and analysis of data in order to answer a specific question.
Kempeitai
The Kempeitai was the military police of the Imperial Japanese Army from 1881 to 1945. The organization also shared civilian secret police, espionage, and counter-intelligence roles within Japan and its occupied territories, and was notorious for its brutality and role in suppressing dissent. The broad duties of the Kempeitai included maintaining military discipline, enforcing conscription laws, protecting vital military zones, and investigating crimes among soldiers.
Comfort women
Comfort women or comfort girls were women and girls forced into sexual slavery by the Imperial Japanese Army in occupied countries and territories before and during World War II. The term "comfort women" is a translation of the Japanese ianfu (慰安婦), which literally means "comforting, consoling woman". During World War II, Japanese troops forced hundreds of thousands of women from Korea, the Philippines, Vietnam, China, and other countries into brothels where they were sexually enslaved and repeatedly raped.
Plague (disease)
Plague is an infectious disease caused by the bacterium Yersinia pestis. Symptoms include fever, weakness and headache. Usually this begins one to seven days after exposure. There are three forms of plague, each affecting a different part of the body and causing associated symptoms. Pneumonic plague infects the lungs, causing shortness of breath, coughing and chest pain; bubonic plague affects the lymph nodes, making them swell; and septicemic plague infects the blood and can cause tissues to turn black and die.
Nazi human experimentation
Nazi human experimentation was a series of medical experiments on prisoners by Nazi Germany in its concentration camps mainly between 1942 and 1945. There were at least 15,754 documented victims from a variety of nationalities and age groups, although the plurality were young adults at the time of the experiment. Although most victims survived, many suffered disability as a result. Nazi physicians and their assistants forced prisoners into participating; they did not willingly volunteer and no consent was given for the procedures.
