When I was in the unit, the captain told me that people were used as experimental animals: Chinese, Russians and Japanese." This is the testimony of a Japanese prisoner of war named Yamamoto Sui, which formed the basis of the Khabarovsk trial. On December 25, 1949, within the walls of Khabarovsk's officers' house, a court began its work, which for the first time in human history saw crimes related to the development and use of bacteriological weapons on people. 12 people were on the dock - these were leaders, scientists and rank-and-file members of the secret units of the Imperial Japanese Army, Units 100 and 731. According to official figures alone, more than 3,000 people died from their actions. The test subjects were not considered people: they were simply called "diaries". In the new season of the "MASHRUMTOUR" project we will go to Khabarovsk, where we will visit the large concert hall of the officers' house of the Eastern Military District. There the trial took place, where the war criminals received their deserved punishment.
