Osami Nagano (永野修身, Nagano Osami; June 15, 1880 – January 5, 1947) was a Marshal Admiral of the Imperial Japanese Navy and one of the leaders of Japan's military during most of the Second World War. In April 1941, he became Chief of the Imperial Japanese Navy General Staff. In this capacity, he served as the navy's de facto commander-in-chief in the Asia-Pacific theater of World War II until his removal in February 1944. After the war, he was arrested by the International Military Tribunal for the Far East but died of natural causes in prison during the trial.
