731部队原队员证实日军曾在中国埋藏毒气弹

The exhibition hall of the crimes of the Japanese Army's Unit 731 disclosed newly organized historical materials on August 12. The oral testimony of the medic Gu Zaki and others from the original 731 Unit Hailar Detachment (Manchukuo 543 Unit) lasted 70 minutes, confirming that the Japanese army buried a large number of gas bombs in China on the eve of their defeat. This provides oral evidence from the perpetrators for further research on the issue of Japan's abandoned chemical weapons.

This testimony was collected during the exhibition hall's evidence-gathering trip to Japan in 2016. The interviewee Gu Zaki, originally named Ozaki, candidly stated in the video that he was 21 years old when he enlisted, and before joining the army, he assisted a doctor and attended a night commercial school. He recounted his experiences in the 731 Unit, such as undergoing three months of training upon enlistment, practicing daily with covered glass petri dishes to prepare culture media, then inoculating with bacteria, and placing them in an incubator until visible colonies formed.

Later, while responsible for managing the breeding of wild mice, Gu Zaki and others needed to record the number of male and female wild mice that gave birth and died. He often carried a shovel, going deep into the trenches to dig and capture wild mice.

Importantly, Gu Zaki revealed the fact that the Japanese army destroyed evidence and buried gas bombs at the time of their defeat. He confirmed that during the retreat, the Hailar Detachment set fire to all military facilities, but the Japanese gas unit secretly buried a large number of gas bombs. He stated, “That was not bacteria, but gas” and “The gas unit did exist, established in the area of Fularji.”

Researchers at the exhibition hall of the crimes of the Japanese Army's Unit 731, including Jin Shicheng, indicated that this oral testimony directly corroborates that the Japanese army abandoned chemical weapons in China at the time of their defeat, and explains the historical roots of the post-war gas hazards, holding significant contemporary relevance.
