former member reveals how Unit 731 secrecy protocols bury atrocities

The Exhibition Hall of Evidence of Crime Committed by Unit 731 of Japanese Imperial Army on Monday released for the first time the testimony of Masakuni Kurumizawa, a former member of the notorious Unit 731, revealing how the Japanese invaders hide their atrocities with strict secrecy protocols.

The 83-minute testimony, recorded in August 1991 during a peace exhibition in Iida City, Japan, was released on the occasion of the 88th anniversary of July 7 Incident, which marked the start of Japan's full-scale invasion of China and China's whole-nation resistance against the Japanese invaders.

Unit 731 is a secret Japanese germ warfare unit during the World War II, infamous for its atrocious human dissections, live experiments, and biological warfare targeting civilians and prisoners. According to Kurumizawa's recollection, while in China, the Japanese invaders enforced strict secrecy rules, requiring all Unit 731 members to keep silent.

"I never told anyone. It was an absolute secret. Even my wife knew nothing. Before going home each time, I had to change clothes. She had no idea I was involved in dissections," Kurumizawa said in the footage.

"Unit 731 was a confidential unit. It had a confidentiality mechanism that forbade members from telling even their families about the crimes they committed there. That is one of the main reasons why Unit 731's crimes were not exposed to the world quickly after World War II," said Jin Shicheng, deputy secretary general of the Harbin Research Institute on History of Bacterial and Gas War of Japanese Invasion in China.

In addition, before its defeat and retreat in 1945, the Japanese invaders blew up major buildings of the Unit 731 headquarters to destroy evidence. During the withdrawal, the unit's commander, Shiro Ishii, issued a secrecy order of "three nots" within the unit, allowing its crimes to remain concealed for decades.

"No. I absolutely could not become a civil servant. I was forbidden to take public office or leak secrets. That was the unit's regulation," Kurumizawa said in the footage, in response to questions about his career after returning to Japan.

"First, after returning to Japan, they were not allowed to contact each other. Second, they were not allowed to work in the medical field. Third, they were not allowed to work as civil servants. But after the 1947 deal between the U.S. and Japan, in which the U.S. granted them immunity in exchange for Unit 731's data, many of these members ended up working in government agencies, hospitals, and universities in Japan. They were actually holding important positions in Japanese postwar society. That is why Japan's medical community has never completely reflected and repented after the war," said Jin.

In the "Roster of Epidemic Prevention and Water Purification Department of Kwantung Army" on display at the Exhibition Hall, 3,497 personnel are registered, the vast majority of whom have passed away.

"Over all these years, only a few former Unit 731 members have voluntarily stood out. Most have remained hidden and stayed silent. Exposing Unit 731's crimes should be a joint mission of all peace-lovers worldwide. Our purpose is to uncover the evidence of Unit 731's atrocities, learn the lessons of history, and look ahead to the future," said Jin.

China's achievements and cooperation initiatives in the technology and innovation sector have been highlighted at the ongoing Zhongguancun Forum (ZGC Forum) in Beijing.

The five-day forum opened on Wednesday and has attracted over 1,000 guests from more than 100 countries and regions to exchange views under the theme of "Full Integration Between Technological and Industrial Innovation".

This year's event showcased over 500 cutting-edge achievements across fields such as embodied intelligence, smart manufacturing and biomedicine, fully demonstrating China's latest scientific and technological advancements and innovations.

"[I'm] really impressed about the level of modernization and dynamism of the technology industry and AI here in China. We need support, commitment and leadership. China is providing all of them and in particular in the emerging technologies, including AI," said Sergio Mujica, secretary-general of the International Organization for Standardization.

At the forum's annual meeting, 60 parallel sessions are scheduled -- 21 of them debuting this year -- furthering global technology exchange.

"China is opening its full technical infrastructure to the world, and I think specifically for the Global South. This acts as a major advancement and it shows the level of responsibility and openness that China is showing towards the advancement of science and the collaboration," said Said Taha, a consultant for the Egyptian Ministry of Education.

At the 2026 Zhongguancun International Technology Trade Fair, part of the ZGC Forum, over 500 high-quality projects and scientific and technological achievements were on display, establishing a multi-level, wide-ranging platform for technology transaction and cooperation.

The attendees hailed the fair for bringing together global companies and facilitating exchanges.

"The innovation here in China is so attractive that a lot of global companies are coming to China in order to do the business deals in order to bring the products to the global markets," said Joseph Scheeren, member of the French National Academy of Pharmacy.

"The ZGC Forum provides an open platform for dialogue, and we hope to participate in more international cooperation in the future to promote Chinese technology and products to the world," said Yang Zhilin, CEO of Moonshot AI, a Chinese tech company.
