Nagao is best known for his photograph of Otoya Yamaguchi assassinating Japanese Socialist Party politician Inejiro Asanuma. At the time Nagao was a cameraman working for Mainichi Shimbun; Hisatake Abo, Nagao's picture editor, told Nagao to cover a debate at Hibiya Hall. As Yamaguchi challenged Asanuma, Nagao changed the focus to fifteen feet from ten feet.
Nagao left the newspaper in 1962 and became a freelance photographer.
Nagao was discovered collapsed in his bathroom on May 2, 2009. It is believed he died of natural causes.
