The Akihabara massacre (Japanese: 秋葉原通り魔事件, Hepburn: Akihabara Tōrima Jiken)[a] was an incident of mass murder that took place on 8 June 2008, in the Akihabara shopping quarter in Chiyoda, Tokyo, Japan. The perpetrator, 25-year-old Tomohiro Katō (加藤 智大, Katō Tomohiro) of Susono, Shizuoka,[1][2] drove into a crowd with a rented truck, initially killing three people and injuring two; he then stabbed at least twelve people using a dagger, killing four other people and injuring eight.[3][4][1][5]

The Tokyo Metropolitan Police Department arrested Katō on suspicion of attempted murder,[1][5] holding him at Manseibashi police station.[6] Two days later on 10 June, he was sent to the Tokyo District Public Prosecutor's Office.[1][2] He was later re-arrested by the police on 20 June on suspicion of murder.[5][7][8] Katō was sentenced to death by the Tokyo District Court in 2011. The sentence was upheld on appeal in 2015,[9] and he was executed on 26 July 2022.[10]
