New evidence of Japanese germ warfare unit made public

The discoveries further suggested that the Japanese army hospital in Harbin was closely related to Unit 731 and was an extension of medical crimes committed by Unit 731, said Jin Shicheng, a researcher with the exhibition hall.

Studies found that the human experiments and germ warfare carried out by Unit 731 were assisted by Japanese wartime medical institutions, said Jin Chengmin, curator of the exhibition hall. "It once again proves that the Japanese invasion of China was a top-down, organized, and planned group crime carried out by the Japanese militarism."

Unit 731 was a top-secret biological and chemical warfare research base established in Harbin as the nerve center for Japanese biological warfare in China and Southeast Asia during World War II.
