A man who murdered and dismembered nine people he met online, has been executed in Japan, in the country's first enactment of the death penalty since 2022.
Takahiro Shiraishi, 34, was executed for killing his young victims, all but one of whom were women, after contacting them on the social media platform now called X.
Dubbed the 'Twitter Killer' he had targeted users who posted about taking their own lives, telling them he could help them in their plans, or even die alongside them.
Justice Minister Keisuke Suzuki said Shiraishi's crimes, carried out in 2017, included "robbery, rape, murder... destruction of a corpse and abandonment of a corpse".
Shiraishi acted "for the genuinely selfish reason of satisfying his own sexual and financial desires" and the murders "caused great shock and anxiety to society", Mr Suzuki said.
"After much careful consideration, I ordered the execution."
Japan and the United States are the only two G7 countries to still use capital punishment, and there is overwhelming support for the practice among the Japanese public.
Shiraishi was sentenced to death in 2020 for the murders of his nine victims, aged between 15 and 26.
After luring them to his small home near the capital, he hid parts of their bodies around the apartment in coolers and toolboxes sprinkled with cat litter in a bid to hide the evidence.
His lawyers had argued Shiraishi should receive a prison sentence rather than be executed because his victims had expressed suicidal thoughts and so had consented to die.
But a judge dismissed that argument, calling Shiraishi's crimes "cunning and cruel", according to reports at the time.
The dignity of the victims was trampled upon," the judge had said, adding that Shiraishi had preyed upon people who were "mentally fragile".
The murders were discovered in autumn 2017 by police investigating the disappearance of a 23-year-old woman who had reportedly tweeted about wanting to take her own life.
Her brother gained access to her Twitter account and eventually led police to Shiraishi's residence, where investigators found the nine dismembered bodies.
There are 100 prisoners on death row in Japan.
Nearly half are seeking a retrial, Mr Suzuki said.
Japanese law stipulates that executions must be carried out within six months of a verdict after appeals are exhausted.
In reality, however, most inmates are left in solitary confinement for years, and sometimes decades.
There is widespread criticism of the system and the government's lack of transparency over the practice.
In 2022, Tomohiro Kato was executed for an attack that killed seven people in 2008, when he rammed a rented two-tonne truck into a crowd in Tokyo's Akihabara district, before getting out and going on a stabbing spree.
The high-profile executions of the guru Shoko Asahara and 12 former members of the Aum Shinrikyo doomsday cult took place in 2018.
