Battles Without Honor and Humanity , also known in the West as The Yakuza Papers, is a Japanese yakuza film series produced by Toei Company. Inspired by a series of magazine articles by journalist Kōichi Iiboshi that are based on memoirs originally written by real-life yakuza Kōzō Minō, the films detail yakuza conflicts in Hiroshima Prefecture.

Kinji Fukasaku was a Japanese film director and screenwriter. Known for his "broad range and innovative filmmaking", Fukasaku worked in many different genres and styles, but was best known for his gritty yakuza films, typified by the Battles Without Honor and Humanity series (1973–1976). According to the Berkeley Art Museum and Pacific Film Archive, "his turbulent energy and at times extreme violence express a cynical critique of social conditions and genuine sympathy for those left out of Japan's postwar prosperity." He used a cinema verite-inspired shaky camera technique in many of his films from the early 1970s.
