Japan Executes 'Twitter Killer' in First Hanging Since 2022

27 June, 2025

Japan has executed Takahiro Shiraishi, dubbed the "Twitter killer," for the 2017 murder and dismemberment of nine people he contacted via social media. This marks the country's first use of capital punishment since July 2022. The Justice Minister authorized the hanging, citing the "extremely selfish" motive for the crimes that shocked the nation. The execution has reignited the long-standing debate on capital punishment in Japan, a practice strongly condemned by international human rights groups.

Unpacked:

Why did Takahiro Shiraishi target his victims on social media?

Shiraishi targeted individuals who had expressed suicidal thoughts online. He contacted them under the guise of offering support or proposing to die together, exploiting their vulnerability for his own sexual and financial motives.

How was Shiraishi ultimately caught by authorities?

Shiraishi was apprehended in October 2017 after police investigated the disappearance of a young woman. They found human remains in his Zama apartment, which led to the discovery of his crimes.

What is the current public opinion on capital punishment in Japan?

Despite international criticism, capital punishment retains overwhelming support among the Japanese public. Many view it as a necessary deterrent and appropriate punishment for severe crimes like serial murder.

How does Japan's use of the death penalty compare to other G7 countries?

Japan and the United States are the only G7 nations that still practice capital punishment. Other G7 members have abolished the death penalty, reflecting broader international opposition to the practice.
