The 1984 murder
In December 1984, a 69-year-old woman who operated a liquor shop in Hino, Shiga Prefecture, disappeared. Her body was found about a month later. A portable safe belonging to her was discovered months after the disappearance. The crime was investigated as robbery-murder.
Hiromu Sakahara, a regular customer at the shop, was questioned during the investigation. He initially denied involvement and was released after an alibi was provided, but police returned to him as the investigation continued.
Confession and conviction
Sakahara was arrested in March 1988 after prolonged questioning produced confession statements. He later retracted the confession and maintained his innocence throughout the court proceedings.
The Otsu District Court sentenced him to life imprisonment in 1995. The Osaka High Court rejected his appeal in 1997, and the Supreme Court allowed the conviction to become final in 2000. Sakahara continued to seek a retrial.
Death in prison and the family's campaign
Sakahara filed a retrial request in 2001. He died from illness in 2011 at age 75 while still serving the life sentence. His family continued the effort to reopen the case after his death.
The second retrial request focused heavily on the reliability of the confession and on evidence disclosed after the original trial, including photographic material related to an investigative reenactment. Courts considering the retrial concluded that the new evidence raised serious doubt about the basis of the conviction.
Supreme Court orders a retrial
On February 24, 2026, the Supreme Court's Second Petty Bench rejected the prosecution's special appeal. That made final the Otsu District Court's 2018 decision to grant a retrial, which the Osaka High Court had upheld in 2023.
Japanese bar associations described the ruling as historically significant because it allowed a posthumous retrial in a serious case in which the former defendant had died while serving a life sentence.
Prosecutors abandon a guilt case
On June 19, 2026, the Otsu District Public Prosecutors Office announced that, after reviewing the record, it would not argue that Sakahara was guilty and would not present new evidence to establish guilt at the retrial.
That announcement makes a posthumous acquittal highly likely, but it is not itself the acquittal judgment. Crime by Region therefore records the present posture precisely: the original murder remains unresolved as to the true perpetrator, while Sakahara's conviction is subject to a court-ordered retrial in which prosecutors have declined to pursue guilt.
What remains unresolved
The victim's killing remains a real, documented murder. The legal system once attributed the crime to Sakahara, but the retrial decisions concluded that the conviction required re-examination. Unless and until a new judgment establishes criminal responsibility, this page does not identify Sakahara—or anyone else—as the proven killer.
