The Chinese film Evil Unbound, depicting Japan’s notorious Unit 731 germ warfare experiments during World War Two, set a box office record for war films in China this year with over 345 million yuan (\$48.5 million) on its first day. The movie dramatizes the horrific human experiments conducted by the Japanese military research base on thousands of prisoners. While Beijing uses the film to highlight Japan’s wartime actions and perceived lack of accountability, its release risks inflaming long-standing tensions between China and Japan, both historically linked to the occupation and suffering during the war.
