Japan on Tuesday executed a man convicted of killing seven people in a truck ramming and stabbing rampage in Tokyo’s popular Akihabara electronics district in 2008, the justice ministry said. Justice Minister Yoshihisa Furukawa said Tomohiro Kato had undertaken “meticulous preparation” for the attack and displayed a “strong intent to kill”. Furukawa said he “approved the execution after extremely thorough scrutiny,” noting that Kato’s death sentence had been upheld by the court system. Kato went on the rampage on June 8, 2008, telling police: “I came to Akihabara to kill people. It didn’t matter who I’d kill.” He was arrested on the spot shortly after the attacks, in which he rammed a rented two-tonne truck into a crowd of pedestrians before getting out and randomly stabbing people. “This is a very painful case that led to extremely grave consequences and shocked society,” Furukawa said Tuesday. Police said Kato documented his deadly journey to Akihabara on Internet bulletin boards, typing messages on a mobile phone from behind the wheel of the truck and complaining of his unstable job and his loneliness.
