Film 731 premieres in Harbin and is released globally, revealing the previously untold story of Unit 731’s WWII atrocities.
The world premiere of the film 731 took place on September 17 in Harbin, shining a light on one of the darkest chapters of World War II.

The movie tells the story of Unit 731, the covert Japanese military unit that carried out human experiments under the guise of “water supply and epidemic prevention” in Harbin’s Pingfang District during the war. On the eve of Japan’s surrender in 1945, civilians were captured and forced into brutal experiments. Victims endured frostbite tests, poison gas trials, and even live dissections, all under false promises of freedom.
Rather than portraying victims as nameless sufferers, the film gives them individuality and dignity. Characters like street vendor Wang Yongzhang emerge as real people with stories, resilience, and spirit. Their resistance—whether through open defiance or silent endurance—highlights the strength of the human spirit in times of unimaginable darkness.

A Decade of Research Behind the Film
Director Zhao Linshan and his team spent a decade on research and production. They collected over one million words of historical documents, conducted extensive field studies, and worked with experts to ensure accuracy. Jin Chengmin, associate researcher at the Unit 731 Evidence Exhibition Hall, served as the film’s historical consultant, carefully reviewing details for authenticity.
731 aims to bridge history and emotion through cinematic storytelling. By combining rigorous scholarship with powerful imagery, the film seeks not only to document atrocities but also to prompt reflection on shared human values.
In addition, the film will be released worldwide starting September 18. It will gradually reach theatres in countries including the United Kingdom, Germany, and France, bringing this untold story to international audiences.
