Kazuo Hara's 1987 Japanese documentary.

The Emperor's Naked Army Marches On is a confrontational 1987 Japanese documentary. It was initiated by Shōhei Imamura, who introduced director Kazuo Hara to its protagonist, the ageing veteran Kenzo Okazaki, a survivor of the desperate battles in Papua New Guinea towards the end of the Second World War. The film follows Okazaki's relentless, increasingly violent and ethically dubious pursuit of his former comrades, uncovering harrowing truths about their execution and the atrocities of the Japanese Imperial Army. It also forces the audience to confront the ethical questions of filmmaking itself, with the camera acting as both witness and perpetrator of a different kind.
