The attacker was dressed as 'Joker' from Batman

According to multiple witness accounts, the attacker donned a green shirt, a blue suit, and a purple coat. His look resembled that of the 'Joker' from the Batman series. Television footage from the scene showed a number of passengers escaping through train windows. Another video showed passengers running from another carriage, which was burning in flames.

A witness, Shunsuke Kimura, who filmed the video, told NHK that he saw passengers desperately running when he heard an explosive noise and saw smoke whirling. Kimura also attempted to jump from the window of the train and hurt his shoulder in the process. "Train doors were closed and we had no idea what was happening, and we jumped from the windows," Kimura noted.

'I thought it was a Halloween stunt'

Another video footage showed passengers scamming to squeeze through the window onto the platform when the train made an emergency stop. "I thought it was a Halloween stunt," one witness told the Yomiuri newspaper. "Then, I saw a man walking this way, slowly waving a long knife," the witness said before adding that there was blood on the knife. "I heard a loud bang and saw flames and smoke in the back. Everyone was panicking," another passenger said. A victim, believed to be in his 60s or 70s lost consciousness after being stabbed. Officers entered the train and approached the suspect where he sat and did not resist arrest.
