Mass killings

R. J. Rummel, a professor of political science at the University of Hawaii, states that between 1937 and 1945, the Japanese military murdered from nearly 3,000,000 to over 10,000,000 people, most likely 6,000,000 Chinese, Indonesians, Koreans, Filipinos, and Indochinese, among others, including Western prisoners of war. "This democide was due to a morally bankrupt political and military strategy, military expediency and custom, and national culture."[29] According to Rummel, in China alone, during 1937-45, approximately 3.9 million Chinese were killed, mostly civilians, as a direct result of the Japanese operations and 10.2 millions in the course of the war.[30] The most infamous incident during this period was the Nanking Massacre of 1937-38, when, according to the findings of the International Military Tribunal for the Far East, the Japanese Army massacred as many as 300,000 civilians and prisoners of war, although the accepted figure is somewhere in the hundreds of thousands.[31] A similar crime was the Changjiao massacre. In Southeast Asia, the Manila massacre, resulted in the deaths of 100,000 civilians in the Philippines. It is estimated that at least one out of every 20 Filipinos died at the hand of the Japanese during the occupation.[32][33] In the Sook Ching massacre, between 25,000 and 50,000 ethnic Chinese in Singapore were taken to beaches and massacred. There were numerous other massacres of civilians e.g. the Kalagong massacre.

Historian Mitsuyoshi Himeta reports that a "Three Alls Policy" (Sankō Sakusen) was implemented in China from 1942 to 1945 and was in itself responsible for the deaths of "more than 2.7 million" Chinese civilians. This scorched earth strategy, sanctioned by Hirohito himself, directed Japanese forces to "Kill All, Burn All, and Loot All."

Additionally, captured allied service personnel were massacred in various incidents, including:

[edit] Human experimentation and biological warfare

Shiro Ishii, commander of Unit 731.

Special Japanese military units conducted experiments on civilians and POWs in China. One of the most infamous was Unit 731 under Shirō Ishii. Victims were subjected to vivisection without anesthesia, amputations, and were used to test biological weapons, among other experiments. Anesthesia was not used because it was believed to affect results.[34]

To determine the treatment of frostbite, prisoners were taken outside in freezing weather and left with exposed arms, periodically drenched with water until frozen solid. The arm was later amputated; the doctor would repeat the process on the victim's upper arm to the shoulder. After both arms were gone, the doctors moved on to the legs until only a head and torso remained. The victim was then used for plague and pathogens experiments.[35]

According to GlobalSecurity.org, the experiments carried out by Unit 731 alone caused 3,000 deaths.[36] Furthermore, according to the 2002 International Symposium on the Crimes of Bacteriological Warfare, the number of people killed by the Imperial Japanese Army germ warfare and human experiments is around 580,000.[37] According to other sources, "tens of thousands, and perhaps as many as 400,000, Chinese died of bubonic plague, cholera, anthrax and other diseases...", resulting from the use of biological warfare.[38]

One case of human experimentation occurred in Japan itself. At least nine out of 12 crew members survived the crash of a U.S. Army Air Forces B-29 bomber on Kyūshū, on May 5, 1945. (This plane was Lt. Marvin Watkins' crew of the 29th Bomb Group of the 6th Bomb Squadron.[39]) The bomber's commander was sent to Tokyo for interrogation, while the other survivors were taken to the anatomy department of Kyushu University, at Fukuoka, where they were subjected to vivisection or killed.[40] On March 11, 1948, 30 people including several doctors were brought to trial by the Allied war crimes tribunal. Charges of cannibalism were dropped, but 23 people were found guilty of vivisection or wrongful removal of body parts. Five were sentenced to death, four to life imprisonment, and the rest to shorter terms. In 1950, the military governor of Japan, General Douglas MacArthur, commuted all of the death sentences and significantly reduced most of the prison terms. All of those convicted in relation to the university vivisection were free by 1958.[citation needed]

In 2006, former IJN medical officer Akira Makino stated that he was ordered—as part of his training—to carry out vivisection on about 30 civilian prisoners in the Philippines between December 1944 and February 1945.[41] The surgery included amputations.[42] Ken Yuasa, a former military doctor in China, has also admitted to similar incidents in which he was compelled to participate.[43]

[edit] Use of chemical weapons

According to historians Yoshiaki Yoshimi and Kentaro Awaya, during the Second Sino-Japanese War, gas weapons, such as tear gas, were used only sporadically in 1937 but in the spring of 1938, however the Imperial Japanese Army began full-scale use of phosgene, chlorine Lewisite and nausea gas (red), and from summer 1939, mustard gas (yellow) was used against both Kuomintang and Communists Chinese troops.[44]

According to Yoshimi and Seiya Matsuno, Emperor Hirohito signed orders specifying the use of chemical weapons in China.[45] For example, during the Battle of Wuhan from August to October 1938, the Emperor authorized the use of toxic gas on 375 separate occasions, despite Article 23 of the Hague Conventions (1899 and 1907)[13] and article V of the Treaty in Relation to the Use of Submarines and Noxious Gases in Warfare[46] A resolution adopted by the League of Nations on May 14 condemned the use of poison gas by Japan.

Another example is the Battle of Yichang in October 1941, during which the 19th Artillery Regiment helped the 13th Brigade of the IJA 11th Army by launching 1,000 yellow gas shells and 1,500 red gas shells at the Chinese forces. The area was crowded with Chinese civilians unable to evacuate. Some 3,000 Chinese soldiers were in the area and 1,600 were affected. The Japanese report say that "the effect of gas seems considerable".[47]

In 2004, Yoshimi and Yuki Tanaka discovered in the Australian National Archives documents showing that cyanide gas was tested on Australian and Dutch prisoners in November 1944 on Kai Islands (Indonesia).[48]

[edit] Preventable famine

Deaths caused by the diversion of resources to the Japanese military in occupied countries are also regarded as war crimes by many people. Millions of civilians in Southeast Asia—especially Vietnam and the Netherlands East Indies (Indonesia), both of which were major rice-growing countries—died during a preventable famine in 1944–45.[49] (See, for example, the articles on the Vietnamese Famine of 1945 and Japanese occupation of Indonesia.)

An estimated 2 million Vietnamese, or 10% of the population then, died during the famine of 1944–45.[50] A later UN report stated that 4 million people died in Indonesia as a result of famine and forced labour during the Japanese occupation.[51]

The sheer volume of murdered civilians posed a formidable logistical challenge when it came to disposing of the bodies. Many Chinese were conscripted into "burial teams", an experience they would later recall as horrifically traumatic.[52]
