Adachi Masao, born in Kitakyushu on the northern tip of Kyushu in 1939, is a director, screenwriter, and anti-imperialist revolutionary active in the world of cinema from in the 1960s-early 1970s and after the mid-2000s. In the early 1960s, he rose to fame in the world of underground experimental cinema as a member of the Nihon University Cinema Club. He collaborated closely with Wakamatsu Koji and Oshima Nagisa as a screenwriter, often under the pen name "De Deguchi", and later joined the independent production company Wakamatsu Pro where he became a key figure of pink film in the 1960s. Representative of the most radical wing of Japanese New Wave cinema, Adachi's filmmaking and theoretical writings are characterized by an attunement to the immediacy and actuality of left-wing revolutionary politics as it unfolds historically. The "Landscape Theory" pioneered by Adachi and his comrades has had a profound impact on generations of moving image makers committed to resisting the operations of power in visions of the everyday. In the early 1970s, Adachi left Japan for Lebanon, where he joined the Popular Front for the Liberation of Palestine (PFLP) and became a spokesperson for the Japanese Red Army (JRA) under the leadership of Shigenobu Fusako. Adachi was arrested and imprisoned in 1997, extradited to Japan in 2000, and returned to filmmaking upon his release. Retrospectives and exhibitions of his work have been held at the Harvard Film Archive, International Film Festival Rotterdam, and the American University of Beirut in recent years.
