China on Monday released the full video testimony of Masakuni Kurumizawa, a former member of the Imperial Japanese Army’s Unit 731, in what officials said was the first public screening of the complete confession. The footage was unveiled at the Exhibition Hall of Evidence of Crime Committed by Unit 731 in Harbin and broadcast by state television. In the hour-long recording, the 94-year-old veteran admits to dissecting about 300 prisoners—mostly Chinese, Korean and Mongolian nationals—while they were still warm, preserving roughly one-third of the bodies as laboratory specimens and burning the remainder. He also details the unit’s broader program of live human experimentation and germ warfare during Japan’s occupation of China. Separately, the Guangdong Provincial Archives displayed a newly obtained personnel list for Unit 8604, another Japanese germ-warfare detachment that operated in South China. The roster, donated by Japanese researcher Seiya Matsuno and sourced from Japan’s National Archives, is the most complete record yet released of the unit’s structure and members, according to Chinese historians. The disclosures come ahead of the 88th anniversary of the July 7, 1937 Lugou Bridge Incident, which marked the start of Japan’s full-scale invasion of China. To commemorate the date, China’s Central Archives opened a seventh batch of 57,000 historical documents—more than 40,000 of them related to the War of Resistance and World War II—bolstering what Beijing says is an expanding body of evidence of Japanese wartime atrocities.
