The horrific human experimentation conducted by Japan’s covert biological warfare division during World War II remains one of the darkest, most brutal chapters in human history. Shifting away from standard Hollywood blockbusters, Well Go USA Entertainment is bringing this crucial, harrowing, horrific history to home video with the release of 731.

Written and directed by Zhao Linshan (The Assassins), the Chinese film anchors its massive historical scope in a deeply intimate, human perspective. The cast features  Wu Jiang (Dragon, A Touch of Sin), Zhiwen Wang (Battle of the Warriors), and Naiwen Li (The Adventure). Qian Sun (Three Weddings) and Ziye Lin (My Blue Summer) round out the cast.

Suffering and Survival Behind the Wire

Set inside the notorious, hidden complex of the Japanese Imperial Army’s Unit 731, the film confronts the reality of prisoners. Victims were held captive and subjected to torturous medical experiments aimed at developing advanced biological and chemical weaponry.

At the center of this nightmare is Wang (Wu Jiang). He is a prisoner reluctantly assigned by the camp guards. He acts as an interpreter and organizer for his fellow captives. Wang becomes the ultimate, heartbroken witness to history. Through his eyes, audiences see an uncompromising, raw story of systemic cruelty. That includes psychological guilt and the desperate instinct for human survival.

The Real History of Unit 731

For decades, the true extent of the atrocities committed by Unit 731 was kept shrouded in secrecy. Officially known as the Epidemic Prevention and Water Purification Department of the Kwantung Army, the unit operated a massive, sprawling complex in Pingfang, in Japanese-occupied Northeast China (then known as Manchukuo) from the mid-1930s until the end of the war in 1945.

Under the command of General Shiro Ishii, the unit carried out lethal human experimentation on thousands of victims, whom the researchers callously referred to as “maruta” (logs). The captives—primarily Chinese civilians and military prisoners, alongside Russian, Mongolian, and Korean victims—were subjected to horrific procedures, including:

There was biological warfare testing: Prisoners were deliberately infected with deadly pathogens such as anthrax, cholera, the bubonic plague, and typhoid to study the progression of diseases. It also tested the effectiveness of biological bomb delivery systems.

Victims faced Body experiments. Victims were exposed to extreme conditions, including induced frostbite, starvation, dehydration, and lethal doses of X-ray radiation, while researchers meticulously documented the limits of human endurance. Some people were left tied up in the snow, their limbs frozen solid, or left until dead.

Doctors conducted invasive, often unnecessary surgeries and organ removals on living patients without anesthesia, believing that the use of narcotics would alter the physiological data they were trying to collect.

In 1945, the Japanese military blew up the Pingfang facilities in an attempt to destroy the evidence of their research. In a controversial turn of history, the U.S. government granted secret immunity from war crimes prosecution to Ishii and his top researchers. All in exchange for the exclusive biological warfare data gathered during the human experiments. The full reality of Unit 731 only gradually came to light decades later through archival discoveries, testimonies from repentant veterans, and the tireless work of international historians.

A Survival Thriller Like No Other

731 is a somber, cinematic examination of historical trauma, serving as both a devastating drama and a vital monument to remembrance of the hundreds of thousands of victims. If you prefer your historical cinema with uncompromising weight and deep respect for the truth, look for this powerful title exclusively on Amazon, on Blu-ray and DVD, starting June 2.
