Tokyo, Japan – In a case that has shocked the nation, Japan has executed Takahiro Shiraishi, known as the “Twitter killer,” for the murder and dismemberment of nine individuals. This marks the country’s first use of capital punishment in nearly three years.

Immediate Impact of the Execution

Shiraishi, aged 34, was hanged at the Tokyo Detention House on Friday. He was sentenced to death in 2020 after admitting to killing nine people, predominantly women. The victims were lured via social media, including the platform formerly known as Twitter.

The execution has reignited debates about the death penalty and the dangers of social media in Japan. The case had captivated the public’s attention due to its gruesome nature and the vulnerabilities exploited by Shiraishi.

Key Details Emerge from the Case

Shiraishi’s arrest in October 2017 followed a police investigation into the disappearance of a 23-year-old woman from Kanagawa Prefecture, who had expressed suicidal thoughts online. Police discovered human remains in his apartment, confirming the horrific nature of his crimes.

9 victims aged between 15 and 26 were murdered by Shiraishi.

The victims had reportedly posted about their suicidal intentions online, making them targets for Shiraishi, who used a pseudonym translating to “hangman” to contact them and lure them to his apartment under false pretenses.

Industry Response and Public Reaction

The execution has sparked a range of reactions, with some supporting the decision as justice served, while others, including families of the victims, express a desire for Shiraishi to have spent his life contemplating his actions.

Justice Minister Keisuke Suzuki stated, “This case, driven by selfish motives such as sexual and financial gratification, resulted in the deaths of nine individuals over two months – a deeply serious incident that has caused shock and anxiety across society.”

By the Numbers: Japan’s Use of Capital Punishment

  • First execution since July 2022
  • Execution method: Hanging
  • Execution dates are not publicly announced beforehand
  • Japan’s approach to the death penalty remains controversial, with executions carried out in secrecy, often with minimal notice to the families and legal representatives of the condemned.

    What Comes Next for Japan’s Legal System?

    The execution of Shiraishi may prompt further examination of Japan’s legal and social systems, particularly concerning mental health support and the regulation of online platforms. The case highlights the need for increased awareness and protective measures for vulnerable individuals online.

    As Japan navigates the aftermath of this high-profile execution, the debate over capital punishment and social media’s role in facilitating crime continues to evolve.
