Iwao Hakamada, who has been on death row for more than half a century, was found guilty in 1968 of killing his boss, the man’s wife and their two teenage children.
He was recently granted a retrial amid suspicions that investigators may have planted evidence that led to his conviction for quadruple murder.
More than half a century spent on death row has taken a heavy toll on Hakamada's mental health, though, meaning he was unfit to attend the hearing where his acquittal was finally handed down.
