Death row in Japan means years, often decades, of solitary confinement in a five-square-meter cell, waiting for an execution by hanging that will be announced only on the morning it happens. Inmates average roughly 15 years under sentence before execution. They cannot speak to other prisoners, cannot walk around their cells during the day, and cannot know when, or whether, the trapdoor will come for them.
Inside the Cell
Under Article 36 of the Act on Penal Detention Facilities and the Treatment of Inmates and Detainees, anyone sentenced to death is held in a single-person room throughout the day and generally barred from contact with other inmates.1Office of the United Nations High Commissioner for Human Rights. Response of the Government of Japan to the Joint Communication from the Special Procedures Each cell measures about five square meters and contains a sink, a toilet, and a desk. Windows are small and barred. Closed-circuit cameras watch the cell around the clock.
The daily routine enforces stillness. Inmates must remain seated during waking hours. They cannot stand and walk around the cell, make noise, or speak without permission. They leave the cell only to shower, roughly 15 minutes two or three times a week, to exercise in a small concrete yard for about 30 minutes on a similar schedule, and to receive the rare visitor.
Entertainment and information are tightly rationed. Television and computers are prohibited. Inmates may hold three books at a time, each subject to administrative approval. A radio is allowed, but the station is chosen for them, not by them.
Japan’s government has defended the regime as necessary for detention and institutional security.2Japanese Law Translation. Act on Penal Detention Facilities and the Treatment of Inmates and Detainees In its response to UN Special Procedures, the government noted that inmates can request contact with staff, voluntary visitors, or chaplains to reduce complete isolation. Outside monitors have reported that the cumulative effect of years of enforced silence and immobility causes serious mental and physical deterioration.
Contact With the Outside
Visits are reserved for close family and legal counsel, held once a week for about 20 minutes, through a separation screen with a guard present. The conversation must be in a language the monitoring officials understand, or it must be translated on the spot.
Mail is censored in both directions. Outgoing letters are capped at one per day of no more than seven pages, and anything the administration considers inappropriate is blacked out or rewritten before it leaves. Phone calls are not permitted at all.
How Long the Wait Lasts
After a District Court imposes a death sentence, the case moves to the High Court and then to the Supreme Court. Once the Supreme Court upholds the sentence, the judgment becomes final and the defendant is officially a death row inmate.3Supreme Court of Japan. Outline of Criminal Justice in Japan
Article 475 of the Code of Criminal Procedure says the Minister of Justice must personally sign an execution order, and that this should happen within six months of the final judgment.4Japanese Law Translation. Code of Criminal Procedure In practice the six-month deadline is treated as advisory. There is no enforcement mechanism and no penalty for missing it. Inmates spend an average of about 15 years on death row, and some wait far longer. Iwao Hakamada spent more than 45 years under a death sentence before his acquittal in 2024.
The result is a prolonged limbo. The legal status is settled, but the date is not, and that uncertainty is the defining feature of the sentence.
Same-Day Notification
Inmates do not learn their execution date in advance. They are told on the morning it happens, usually just hours before. Families are informed only afterward. Every morning on death row carries the possibility of being the last.
In 2021, two inmates sued in Osaka District Court, arguing that same-day notification violates Article 31 of the Japanese Constitution, which guarantees due process. They said the practice leaves no opportunity to contact a lawyer or file a legal challenge. In April 2024, the court rejected the claim. Presiding Judge Noriko Yokota found that same-day notification “has a certain rationality in order to stabilize the sentiments of death row inmates and to ensure a smooth execution.” The court declined to issue an explicit constitutional ruling, leaving the broader question unresolved.
The Execution Itself
Japan carries out executions by hanging, as specified in Article 11 of the Penal Code.5Japanese Law Translation. Japan Penal Code The procedure takes place in a dedicated chamber inside the detention facility, using a trapdoor mechanism. Several correctional officers press separate buttons at the same moment, and only one of the buttons is wired to the trapdoor. The design is intended so that no single officer knows which of them triggered the drop.
Retrials, Exonerations, and Pardons
Death row inmates can petition for a retrial under Article 435 of the Code of Criminal Procedure. Grounds include new evidence that would justify an acquittal, proof that trial evidence was fabricated, or misconduct by officials involved in the case.4Japanese Law Translation. Code of Criminal Procedure Filing does not automatically pause an execution. Prosecutors have discretion to suspend it, but no obligation.
Retrials are rare, and the pattern of outcomes is stark. Since World War II, five death-sentenced prisoners in Japan have received retrials, and all five were exonerated. Hakamada’s case is the most prominent. A former boxer, he was convicted in 1968 of a quadruple murder on a 2-1 vote of a three-judge panel, and his sentence was finalized in 1980. His legal team filed for a retrial in 1981. A court did not grant one until 2014, after DNA testing showed the blood-stained clothing used to convict him did not match Hakamada or the victims. On September 26, 2024, the Shizuoka District Court acquitted him, finding that key evidence had been fabricated. In March 2025, he was awarded roughly 217 million yen, about $1.4 million, in compensation.
There is no formal pardon process. The Prime Minister technically has the power to commute a sentence, but there is no established procedure for requesting a pardon, no deadline for a government response, and no requirement to explain a refusal. An execution can proceed while a pardon petition is pending.
The Current Execution Pause
Japan has not carried out an execution since July 26, 2022, when Tomohiro KatÅ was hanged for a 2008 stabbing spree in Tokyo’s Akihabara district that killed seven people. The pause has now lasted several years. No official moratorium has been declared, and the government has not publicly explained the gap. Some observers have attributed it to heightened international scrutiny during Japan’s 2023 presidency of the G7.
Who Ends Up on Death Row
Japanese law lists 19 offenses that can carry the death penalty, spread across the Penal Code and several special statutes, including insurrection, inducing foreign aggression, arson of an inhabited building, contaminating a water supply resulting in death, hijacking resulting in death, and piracy resulting in death.6CrimeInfo. Death Penalty in Japan In practice, almost every death sentence comes from a murder case, usually involving multiple victims or a killing committed during a robbery. Since 1983, judges have applied the Nagayama Criteria, a Supreme Court framework that weighs nine factors including the number of victims, the defendant’s motive, the method of killing, and the degree of remorse.7Kansai University of International Studies. Faculty of Psychology – How Many People Must I Kill to Get the Death Penalty The number of victims carries the most weight: a death sentence for a single killing is difficult to secure, while three or more victims makes it near-certain.
Public support for the system remains high. A 2024 government survey found that 83.1 percent of respondents consider the death penalty unavoidable for certain crimes, and Japan has consistently declined international calls to impose a formal moratorium.
