The years leading up to World War II saw an increase in the use of biological and chemical warfare in Japan, spearheaded by Major-General Ishii Shiro. BW most commonly took the form of anthrax, glanders, and plague, while chemical warfare included tear, smoke, and other poison gases. The proliferation of these two tactics in Japan, outlawed by the 1929 Geneva Convention, was enabled by the mechanized nature of the project. Shiro had great factories built in Manchuria and other areas of China. These “factories of death” included the infamous Unit 731 and were developed for research and human experimentation revolving around chemical and biological warfare.
