Takahiro Shiraishi lured his mostly young, female victims through the social media platform, dismembering their bodies after killing them

Japan has executed a death row prisoner, public broadcaster NHK and other media outlets said on Friday, the first time since 2022 that the country has enacted capital punishment.

The justice ministry declined to confirm the hanging but NHK, citing government sources, said the prisoner was 34-year-old Takahiro Shiraishi, who murdered nine people in 2017.

Shiraishi - dubbed the “Twitter killer” - was sentenced to death for murdering and dismembering nine people he met on the social media platform, now called X.
