Hiroo Onoda

Onoda initially held out with three other soldiers: one surrendered in 1950, and two were killed, one in 1954 and one in 1972. The men did not believe flyers and letters from their families stating that the war was over. They survived on wild fruits, game, and stolen rice, and occasionally engaged in shootouts with locals and the police. Onoda was contacted in the jungles of Lubang by a Japanese explorer in 1974, but still refused to surrender until he was formally relieved of duty by his former commanding officer, Major Yoshimi Taniguchi, who flew from Japan to the island to issue the order.
Onoda surrendered on 10 March 1974, and received a hero's welcome when he returned to Japan. That year he wrote and published a best-selling autobiography, and later moved to Brazil, where he became a cattle rancher. In 1984, Onoda returned to Japan, where he died in 2014 at the age of 91.
