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.

Yakuza film is a popular film genre in Japanese cinema which focuses on the lives and dealings of yakuza, Japanese organized crime syndicates. In the silent film era, depictions of bakuto as sympathetic Robin Hood-like characters were common.
