Overview

  • Takahiro Shiraishi was hanged at Tokyo Detention House on June 27 after Justice Minister Keisuke Suzuki issued the execution order following his 2020 death sentence.
  • Shiraishi was convicted of murdering, raping and dismembering nine victims aged 15 to 26 whom he contacted through Twitter after they posted suicidal thoughts.
  • Investigators discovered the victims’ dismembered remains stored in coolers and containers in Shiraishi’s Zama apartment in October 2017.
  • The execution is Japan’s first since July 2022, underscoring its retention of capital punishment alongside the United States among G7 nations.
