Leading experts in China recently revealed that at least 3,000 people were killed by germ warfare experiments the Japanese army's notorious Unit 731 conducted in its headquarters in Harbin, capital of northeast China's Heilongjiang province, from 1939 to 1945 during the Japanese invasion of China. Researchers have acquired detailed information on the victims, which is regarded as direct evidence of the atrocity of Japanese troops in China.

Information on the victims is explicit, including the name, birthplace, age, occupation, address, educational background and even a photo of each victim.

These will be displayed in the Exhibition Hall of Criminal Evidence of the Unit 731 of the Japanese Army Aggression against China.

During World War II, the secretive Japanese detachment Unit 731 conducted biochemical experiments on living people in its base in Harbin in order to develop germ warfare weapons that could spread the bubonic plague, typhoid, anthrax and cholera. More than 3,000 Chinese were killed by the germ experiments in horrific ways - frozen, bombed, roasted, infected, injected and dissected. Some 300,000 others were affected by the tests.

To cover up its crimes, Unit 731 destroyed most documents relating to the germ experiments when the Japanese fled China. During the past ten years, Chinese researchers have uncovered documents from the unit, including some related to the biochemical tests.

Experts say the large amount of documents and testimonies prove that experiments were carried out on Mongolians, Koreans, Russians, British and Dutch, but mostly Chinese.
