Japan's Pachinko Execution and the Death Penalty's Quiet Future

A first execution, a familiar pattern

Sunao Takami died Friday morning at the Osaka Detention House. He was 58. Five people died in his 2009 arson attack on a pachinko parlor, and 10 were injured. Takami turned himself in the next day.

His execution matters less for what happened than for what it signals. It is the first carried out under Prime Minister Sanae Takaichi’s administration, and Justice Minister Hiroshi Hiraguchi convened a hastily arranged news conference to justify the decision within hours. The word ‘hastily’ is important. Hiraguchi’s statement was terse — extraordinary consequences, widespread shock, careful consideration — but it read like a performance of resolve, not reflection.

Japan now executes at a pace that contradicts its own bureaucratic habit. The average death-row inmate waits 17 years and five months. Takami’s conviction became final in 2016. The gap between sentencing and execution shrank under the current government, and that compression is the story, not the crime.

The numbers no one disputes

One hundred inmates remain on death row in Japan. Eighty-three percent of the public supports capital punishment, according to a government poll conducted in October 2024. Sixteen and a half percent want abolition.

Those numbers are real. They are also incomplete.

Japan does not have life imprisonment without parole. Parole is theoretically available to those serving life sentences, but it is rare. In the decade through 2024, only 96 life-sentence inmates received parole. Out of 1,650 prisoners serving life terms in 2024 alone, just one was released through that channel. The near-absence of a genuine alternative to execution is the structural engine behind Japan’s retentionist stance. Without life without parole, the state cannot offer a proportional punishment for the worst crimes except death.

Lawmakers have discussed reforming this gap. The proposal has not gained traction. That is the quiet barrier: not popular opinion, but the absence of a credible sentencing substitute.

International pressure, domestic indifference

By the end of 2025, 145 countries had abolished the death penalty by law or in practice, according to Amnesty International. Japan remains in the shrinking group that continues to carry out executions as a routine part of its criminal justice system.

The pressure is not new. It comes from the United Nations, the European Union, and human rights organizations. It has not moved Japan. What is new is the acceleration of executions relative to previous administrations, and the political framing of each one as a necessary act of justice rather than a reluctant duty.

Hiraguchi’s language this week — ‘unavoidable’ — repeated a line of reasoning that appeared in a 2024 roundtable report which itself cast doubt on the death penalty’s effectiveness as a deterrent and warned about its impact on Japan’s international reputation. The government cited that same roundtable report while simultaneously proceeding with executions. That contradiction is the operating logic: acknowledge the criticism, dismiss its force, continue.

The wrongful-conviction shadow

The 2024 roundtable report also flagged the risk of wrongful conviction. The case of Iwao Hakamata made that risk visible to the public. Hakamata spent 44 years on death row before his exoneration in 2024, following the disclosure of new evidence by prosecutors. He had been convicted of a 1966 quadruple murder in Shizuoka Prefecture.

Hakamata’s case triggered a revision to the criminal procedural law, passed in July 2025, designed to speed up retrial processes and improve access to evidence for applicants. The reform is modest. It does not address the deeper question that the roundtable raised: if human courts are fallible, and the death penalty is irreversible, how can the system justify its existence at all?

The answer, in practice, is that Japan has not yet answered it. The state proceeds because the public supports it, because no alternative sentence exists, and because no court has struck down the hanging method despite defense challenges to its constitutionality.

Who wins, who loses

Takami’s execution satisfies a political demand for visible enforcement of criminal justice. It gives the Takaichi administration a concrete act of governance in a period where the prime minister’s portfolio has drawn scrutiny for other reasons. Hiraguchi gains credibility with a constituency that treats leniency as weakness.

The losers are harder to name because they are structural. They include the 100 inmates waiting their turn, whose average wait time is measured in decades. They include defense lawyers who face the same procedural wall every time they challenge an execution order. They include Japan’s diplomatic standing in forums where human rights benchmarks matter, however selectively.

International bodies will issue statements. They always do. The statements carry no penalty. Japan will continue executing.

What happens next

The next execution is inevitable. The system is built for continuity, not pause. What could change is the political calculus around it. If the Takaichi government faces sustained diplomatic pressure — from trade partners, from multilateral human rights mechanisms, from domestic legal challenges that gain momentum — the cost-benefit analysis of each execution shifts slightly.

So far, that shift has not happened. The last execution before Takami’s was in June 2025, when Takahiro Shiraishi was hanged for killing nine people he met through social media in Zama, Kanagawa Prefecture. Two executions in seven months. That pace, if maintained, would mark a significant departure from the previous administration’s rhythm.

Japan’s death penalty is not ending soon. The structural conditions — no life-without-parole alternative, strong public support, a political class that treats abolition as politically toxic — all reinforce retention. But the gap between Japan’s domestic practice and the global trajectory is widening, not narrowing. Every execution deepens that gap.

The question is whether Japan’s leaders consider that distance a cost worth paying. So far, the answer has been no. The Takami execution confirms it.
