Li Han-no (李半能) was a Korean tramway conductor who killed eight people and wounded nine others in Tokyo, Japan on June 1, 1921.[1][2][3][4][5]

Li came to Tokyo from Korea in August 1920, where he secured a job as motorman on street car, and reportedly became one of the most popular and industrious street car employees. He lived together with his wife in a house that he shared with the family of one of his colleagues, a man named Mr. Endo.

On May 29 Li had a serious disagreement with Endo over a trivial matter. They were separated by a friend and afterwards the three drank together and made peace, however, the argument flared up again when Endo an Li were drinking sake at their home during the night from May 31 to June 1. Eventually Li grabbed a stone hammer and hit Endo, killing him almost instantly. He next killed Mrs. Endo and her two children when they tried to intervene, also struck down his own wife when she entered the room, and then ran to the adjoining house of Mr. Imahoke, another of his colleagues. There he killed Imahoke, his wife, and two of their children, and seriously wounded their two other children. Afterwards he rushed out into the street, seriously injured five pedestrians, as well as a policeman, who tried to stop him, and finally was subdued and arrested by three other police officers. Li was later sentenced to life imprisonment.[6]
