TOKYO — As Japan’s defeat marking the tip of WWII nears its eightieth anniversary, and a few occasions fade from dwelling reminiscence, historical past is hardly consigned to books. It lives on in unhealed wounds, still-simmering disputes, freshly unearthed discoveries, and historic classes ready to be realized.
The discharge of WWII-era navy paperwork this yr has given a lift to researchers digging into Japan’s infamous germ warfare program, which lasted from 1936 to 1945. And in China, the premiere of a movie about this grotesque episode in historical past was postponed with out clarification, inflicting a web based outcry.
Titled 731 Biochemical Revelations in English, the movie tells the story of Chinese language victims of the Japanese Imperial Military Unit 731’s inhumane medical experiments.
When the screening was canceled and later pushed again to September with out clarification, some movie followers questioned the authorities’ motives, questioning whether or not the transfer was supposed to keep away from a spat that might harm fragile ties between Beijing and Tokyo.
“Just because the movie exposes scars, does that mean people should choose to forget that part of history?” requested state-run Hunan Satellite tv for pc TV anchor Liu Jiaying in a social media video. “This film is not only a retelling of the past but also a warning to the future,” she added.
First-hand accounts are uncommon
One of many final eyewitnesses ready and keen to talk about Unit 731 is 95 year-old Hideo Shimizu, who lives in central Japan’s Nagano prefecture.
He joined Unit 731’s Youth Corps at age 14 and arrived at unit headquarters in Japanese-occupied Northeast China in 1945, 5 months earlier than the tip of the battle.
In an interview at his house, he says he assumed he can be given some manufacturing job, so he was shocked to see docs in white lab coats on the headquarters.

He says he by no means imagined he can be doing something associated to medication, a lot much less working in a unit accused of dissecting stay prisoners, some with out anesthesia, infecting them with illnesses or conducting germ warfare towards Chinese language troopers and civilians.
Shimizu remembers that the primary inkling he bought that one thing horrible was taking place was when he was led someday right into a room stuffed with specimens of human organs in glass jars.
“The most shocking thing for me,” he remembers, “was a specimen of a whole female body with a fetus in its womb.”
Shimizu says he himself grew to become significantly in poor health, after an older unit member gave him a chunk of bread, and he believes that the unit carried out experiments by itself youth corps trainees.
As Japan’s defeat loomed, unit 731 members had been instructed to destroy proof — and witnesses. Unit 731 docs referred to as the folks they experimented on “maruta,” or logs, in different phrases, not human.
“I did not see any of the maruta alive,” Shimizu says. “All I did was collect their bones and put them in a bag,” after they’d been killed and their our bodies burned.
Unit 731 is estimated to have killed round 3,000 folks, whereas bioweapons developed by different branches of this system are believed to have killed way more.
Japan’s authorities has by no means apologized for Unit 731’s actions, and insists that it has discovered no proof that the unit experimented on Chinese language prisoners, although a Tokyo court docket dominated in 2002 that the navy had performed such experiments and waged organic warfare.
Final yr, Shimizu traveled to China to apologize. He has confronted criticism in Japan for talking out. Others, like Hideaki Hara, a former faculty instructor who has curated a part of an exhibit coping with Unit 731 at a neighborhood museum in Nagano, assist him.
“When we talk about the war, it’s easier to talk about ourselves as victims, such as of the atomic bombings,” Hara says. “But our role as perpetrators is not often discussed. People don’t want to talk about it.”
Uncovering a secret historical past
However 77-year previous Katsutoshi Takegami desires to speak. A number of years in the past, in his house in Nagano prefecture, he found a trunk that belonged to his father.
It contained images that confirmed his father serving in Unit 1644, one other a part of Japan’s biowarfare program. Since then, Takegami has been researching his father’s navy service.

“If you kill a lot of people, you become a hero and get promoted,” he says. “I was worried that my father had done something bad, and that’s how I got started investigating this thing.”
In Could, on the request of researchers, Japan’s nationwide archives made public Unit 1644’s personnel rosters. Takegami hopes to make use of the rosters to trace down any surviving members of the unit.
“I feel the personnel rosters are a treasure,” says Lv Jing, a historian at Nanjing College, within the metropolis the place Unit 1644 was primarily based. She believes the rosters will allow researchers to higher perceive the construction of Japan’s germ warfare system.

Researchers in recent times have found a community of items, stretching from Unit 731 within the north to Unit 8604 in southern China’s Guangzhou metropolis, and all the way down to Unit 9420 in Singapore.
Lv says that every unit “tried to adapt to local conditions, solving problems in the environment they were fighting in, and using them against their enemy.”
With euphemistic names resembling “anti-epidemic and water supply” items, their job was to maintain their very own troops wholesome, whereas getting their enemies sick, by spreading illnesses resembling plague and malaria.
After the battle, a global tribunal, generally known as the Tokyo Trial — much like the Nuremburg trials in Germany — sentenced seven Japanese officers to loss of life for battle crimes.
However Lv Jing notes that Unit 731’s leaders returned to Japan, the place lots of them led illustrious careers as heads of medical establishments and pharmaceutical corporations.

That is as a result of the U.S. gave Unit 731 leaders immunity from prosecution, and withheld proof of their battle crimes from the tribunal, in alternate for the info from the unit’s medical experiments. The U.S. authorities saved the main points of Unit 731 and its immunity deal secret for many years.
“It is a lapse of justice to the highest degree,” says Cambridge College professor of East Asian Historical past Barak Kushner. “And of course, the reason it’s kept out mainly is Americans want the data for themselves and they don’t want the Soviets to get it.”
Equally, Kushner notes, the U.S. gave German scientists, together with former Nazi get together members, immunity in alternate for his or her assist with U.S. missile and area packages, a program generally known as “Operation Paperclip.”
In Japan, the U.S.’ overriding concern was to rebuild the nation, Kushner says, right into a bulwark towards communism.
“I think the immunity offered in that situation reflects the tenor of the times, the political situation, and perhaps the limits of what sort of justice was achievable” for battle crimes within the instant post-war period, Kushner says.
It was one necessary episode, he provides, by which American beliefs of justice took a again seat to self-interest and nationwide safety.
