Takahiro Shiraishi was hanged for the murders of eight women and one man whose body parts he concealed in his small apartment.

Japan has executed a man who was found guilty of killing and dismembering nine people he made contact with on social media, the first use of capital punishment in the country in nearly three years.

Takahiro Shiraishi was hanged on Friday after he was sentenced to death for the 2017 murders of eight women and one man in his apartment in Zama city in Kanagawa near Tokyo.

He was dubbed the “Twitter killer” as he had contacted his victims via the social media platform, now known as X.

Shiraishi admitted to committing the murders after reaching out and offering to help people – who were contemplating suicide – to die. He had stashed bits of the bodies of his nine victims in coolers around his small apartment, according to media reports.
