1August 993 14 "Asahi shimbun" reported on the front page that the business logs of Japanese officers in that year kept by the library of the Defense Research Institute of the Defense Agency recorded that 73 1 troops of the Japanese army secretly developed bacterial weapons in northeast China and actually used them in various parts of China.
According to Asahi Shimbun, China's data show that 73 1 troops fought germ warfare in China. However, Japanese data confirm that this is the first time.
According to the log records of the combat unit at that time,1941year1October 4th, a 1997 light bomber planted a 36-kilometer-long flea belt in Changde City, Hunan Province. Two weeks later, there was a report on the results of the plague epidemic. The log of 1940 September 18 also recorded that Ningbo, Jinhua, Yushan, Taizhou and Lishui were the targets of bacterial warfare attacks. On June 7th of the same year 10, the magazine recorded that six attacks had been launched so far, and according to this result, the specific methods of spreading bacteria later were discussed.
1935 to 1936, according to the secret order of emperor hirohito, the Japanese military department established two secret germ units in northeast China, one of which was the kwantung army epidemic prevention and water supply department led by Shiro Ishii, and later renamed as 73 1 unit.
73 1 troops are stationed in the bungalow area in the south of Harbin, covering an area of more than 30 square kilometers. It is strictly confidential to the outside world. Just building a bacterial experimental factory in Sifang, more than 3,000 workers from China who participated in the construction were secretly killed. This unit has more than 3000 bacteriologists and technicians, and has its own special aviation team. Four detachments, Hailar, Sunwu, Mudanjiang and Linkou, were also established. The 73 1 Army has eight departments, which are responsible for the experiment and production of bacterial weapons. Cultured bacteria include plague, cholera, gangrene, typhoid fever and paratyphoid fever.
Not only animals but also living people were used in the experiment. To this end, there are secret prisons that can accommodate three or four hundred people. The army is also responsible for cultivating parasites that spread bacteria, making special weapons that spread bacteria, and having large-scale production equipment. With these equipment, no less than 30 trillion microorganisms can be produced in a production cycle, and 300 kilograms of Yersinia pestis and tens of millions of fleas can be cultivated every month.
The most cruel thing is to test bacteria with living people. The living people who have stood the test include anti-Japanese patriots from China, innocent people, and people from the Soviet Union, Mongolia and North Korea. They call these people wood and slaughter them at will. The Japanese army experimented with living people in various ways, and the means were extremely cruel. The most common experiments are bacterial liquid injection experiment, bacterial diet experiment, poisonous gas experiment, frostbite treatment experiment and flame thrower lethal experiment.
The Japanese army not only tested a large number of bacteria on living people, but also performed vivisection on people who were sick but not dead. Kiyoshi Kawashima, the former minister of bacterial production of 73 1 Army, admitted in Boli Military Court that during the five years when 73 1 Army entered the bungalow, at least 3,000 people were killed by the deadly bacteria infected by the factory.
The Japanese invaders not only made bacterial weapons on a large scale, but also blatantly violated international law. They used a lot of germ weapons in the war of aggression against China, which brought great disasters to the people of China and committed unforgivable crimes.
