Japan executed a man on Friday who killed nine people after contacting them on social media, the first use of capital punishment in the country in nearly three years.

Takahiro Shiraishi, known as the “Twitter killer,” was sentenced to death in 2020 for the killings in 2017 of the nine victims, most of whom had posted suicidal thoughts on social media. He was also convicted of sexually abusing female victims.
