The Emperor's Naked Army Marches On (ゆきゆきて、神軍, Yuki Yukite Shingun) is a 1987 Japanese documentary film by director Kazuo Hara.

The documentary centers on Kenzō Okuzaki, a 62-year-old veteran of Japan's campaign in New Guinea in the Second World War, and follows him around as he searches out those responsible for the unexplained deaths of two soldiers in his old unit.

At the end of the war, the Japanese garrison in New Guinea was crammed into a small area and almost completely cut off from food supplies, leading to starvation and eventually to cannibalism.

An epilogue shows pictures of newspaper headlines where it is revealed that Okuzaki attempted to kill Koshimizu, whom he holds responsible for the deaths of the two soldiers.

Errol Morris listed it as one of his top 5 favorite films for Rotten Tomatoes,[3] while Mark Cousins credited it with reviving his own film-making.
