Takahiro Shiraishi, known by the media as the "Twitter Killer," has been executed by hanging after being convicted of murdering and dismembering the bodies of nine people he met online in 2017.
This is the first execution case in Japan since 2022.
According to reports, Shiraishi lured his victims – mostly young women, aged 15 to 26 – to his apartment near Tokyo, posing as someone who “offered help to those who wanted to die” after contacting them through the social media platform now known as X (formerly Twitter). He would then kill them, dismember them and hide their remains in small refrigerators scattered throughout his apartment.
Japanese Justice Minister Keisuke Suzuki told the media: “Shiraishi’s crimes include robbery, rape, murder, destruction and abandonment of the body. Nine victims were raped, strangled, robbed and their bodies were dismembered. Some body parts were thrown in the trash, others were stored in boxes.”
He added that the decision to execute was made "after much careful consideration."
Japan is one of two G7 countries that still uses the death penalty, alongside the United States. In a 2024 government poll, 83% of Japanese considered the death penalty "inevitable."
However, Japan's execution system has drawn widespread criticism - prisoners are often held in solitary confinement for years or decades, unaware of their execution date. They are given only a few hours' notice of their execution, usually in the early hours of the morning, which severely affects their mental state.
As of December 2023, 107 people were awaiting execution in Japan.
One of the most well-known cases in recent years was that of the Aum Shinrikyo sect, who were executed in 2018 for the sarin gas attack on the Tokyo subway in 1995, which killed 14 people and poisoned thousands more.
