Iwao Hakamada (袴田 巖, Hakamada Iwao, born March 10, 1936) is a Japanese former professional boxer who was sentenced to death on September 11, 1968, for a 1966 mass murder that became known as the Hakamada Incident. On March 10, 2011, Guinness World Records certified Hakamada as the world’s longest-held death row inmate. In March 2014, he was granted a retrial and an immediate release when the Shizuoka district court found there was reason to believe evidence against him had been falsified.
