Summary

Japan has executed Takahiro Shiraishi, the so‑called “Twitter killer,” marking the country’s first use of capital punishment since 2022. Shiraishi was sentenced to death in 2020 for luring nine people—mostly young women who had posted about suicidal thoughts—via social media in 2017, then raping, murdering, and dismembering them. The case shocked the nation, spurred platforms like Twitter to tighten rules on self-harm content, and has reignited debate over Japan’s death penalty, which is conducted in secrecy and retains strong public support despite criticism over inmate treatment and miscarriages of justice. Officials cited the crimes’ extreme cruelty and societal impact, while some victims’ families expressed mixed views on execution versus lifelong imprisonment.

Key Points

  • Execution is Japan’s first since 2022 and carried out by hanging.
  • Shiraishi murdered and dismembered nine people he lured via Twitter in 2017.
  • Case prompted stricter social media rules on self-harm promotion.

Japan executed Takahiro Shiraishi, the “Twitter killer,” for murdering nine people in 2017—the country’s first execution since 2022.

Discovered after police searched for a missing woman, the case shocked Japan, sparked debate about online suicide content, and led Twitter to tighten rules against promoting self-harm. Despite his lawyers’ “murder with consent” defense, Shiraishi admitted the victims did not consent and was sentenced to death in 2020. Japan’s justice minister said the crimes were driven by selfish sexual and financial motives.
