Japan executes ‘Twitter killer’ who murdered and dismembered nine people

A man guilty of murdering nine people, most of whom had posted suicidal thoughts on social media, has been executed in Japan.

Takahiro Shiraishi, known as the “Twitter killer”, was sentenced to death in 2020 for the 2017 killings of the nine victims, who he also dismembered in his apartment near Tokyo.

His execution was the first use of capital punishment in the country in nearly three years and it was carried out as calls grow to abolish the measure in Japan since the acquittal of the world’s longest-serving death-row inmate Iwao Hakamada last year.

He was freed after 56 years on death row, following a retrial which heard police had falsified and planted evidence against him over the 1966 murders of his boss, wife and two children.

Eight of Shiraishi’s victims were women, including teenagers, who he killed after raping them. He also killed a boyfriend of one of the women to silence him.

Police arrested him in 2017 after finding the bodies of eight females and one male in cold-storage cases in his apartment.

Investigators said Shiraishi approached the victims via Twitter, offering to assist them with their suicidal wishes.

Justice Minister Keisuke Suzuki, who authorised Shiraishi’s hanging, said he made the decision after careful examination, taking into account the convict’s “extremely selfish” motive for crimes that “caused great shock and unrest to society”.

“It is not appropriate to abolish the death penalty while these violent crimes are still being committed,” Mr Suzuki said.

There are currently 105 death row inmates in Japan, he added.
