Unit 1644 was established after the [[Nanjing Massacre]]. It was originally established as an Epidemic Prevention and Water Supply Department (EPWSD) (Boeki Kyusui Bu). It soon became a center for the testing of [[chemical weapon|chemical]] and [[biological weapon]]s. It was part of the human experimentation facilities operated by [[Shiro Ishii]]. Unit 1644 conducted tests to determine human susceptibility to a variety of harmful stimuli ranging from infectious diseases to poison gas. It was the largest germ experimentation center in China. Unit 1644 regularly carried out human [[vivisection]]s as well as infecting humans with [[cholera]], [[typhus]], and [[bubonic plague]]. It is possible that the Japanese, who controlled Manchuria at the time, designated the unit "1644" because it was in this year that the [[Manchu Dynasty]] took control of China. ==See also== *[[Japanese war crimes]] ==References== *Hal Gold, Unit 731 Testimony, Yenbooks: Singapore, 1996, p.151-152 *"Inter Armma Enim Silent Leges: The Impunity of Japan's Secret Biological Warfare Unit", Patrick Fong, New England Journal of International and Comparative Law, Vol. 6, p. 1-15. ==External links== *http://www.lit.osaka-cu.ac.jp/~tsuchiya/gyoseki/presentation/ICHS05oral.html [[Category:Japanese human experimentation]] [[Category:Biological warfare facilities]] [[Category:Chemical warfare]] [[Category:Imperial Japanese Army]] [[Category:Japanese human experimentation]] [[Category:Second Sino-Japanese War]] [[Category:War crimes in China]] {{IJA special research units}}
