Kenzo Okuzaki (February 1, 1920 – June 16, 2005) was a veteran of Japan's Second World War campaign in New Guinea. Okuzaki was the subject of the documentary film The Emperor's Naked Army Marches On, directed by Kazuo Hara. The documentary follows the veteran Okuzaki's attempt to uncover the circumstances behind the deaths of two of his wartime comrades-in-arms, Jinpei Nomura and Private Yoshizawa. Okuzaki had been captured in the jungles of New Guinea in 1944; of the 1,000 troops in his unit only 30 survived, ten of whom appear in the films. Okuzaki uses the occasion of the filmmaking to doggedly pursue the truth behind the deaths of his friends, who were executed by a firing squad composed of his own unit, after the end of the war. Okuzaki confronts the survivors of his unit with persistent questioning, and when they stonewall he literally beats the story out of them.
Okuzaki died on June 16, 2005 in Kobe, Japan. Shizumi, Kenzo Okuzaki's wife, accompanies her husband on Kenzo's missions. She died in 1986.
