As a majority of the international community has abolished capital punishment. Japan and the U.S. are the only two countries in the Group of Seven leading industrialized nations that put people to death. The execution of Takami Sunao—an arsonist whose 2009 attack in Osaka killed five—on August 21, 2026, was Japan’s first use of capital punishment in just over a year. Over a Decade from Sentencing to Execution Takami Sunao was executed on August 21, 2026 , for a 2009 arson attack at an Osaka pachinko parlor that killed five people. In July 2009, Takami poured gasoline on the floor of a pachinko parlor in Osaka and set it alight, killing 5 customers and staff members and injuring 10 more. While the defense argued that he was in a state of diminished capacity, the Supreme Court finalized his death sentence in February 2016. The execution took place 17 years after the initial crime and 10 and a half years after the death sentence was finalized.
The ruling throws another wrench into the long-running death penalty case involving Khalid Sheikh Mohammed on the eve of the 25th anniversary of the deadliest U.S. terrorist strikes. A U.S. military judge has thrown out Khalid Sheikh Mohammed's 2007 confession to FBI agents about his alleged lead role in the 9/11 attacks, ruling that it wasn’t given voluntarily and can’t be used against him at trial. The Aug. 28 ruling by the trial judge, Air Force Lt. Col. Michael Schrama, throws yet another wrench into the long-running death penalty case on the eve of the 25th anniversary of America’s deadliest terrorist strike that killed nearly 3,000 people.
