Genjo Sakaguchi (born 1964) was a Japanese yakuza criminal who worked as an enforcer for the Shibusawa-gumi subsidiary of the Dojima-gumi family during the 1980s. At 5:00 PM on 19 December 1988, he was sent with a gang of hitmen to ambush and kill Goro Majima at the Empty Lot, but Majima beat down all of his assailants and then headed off to the Sebastian Building to confront Sohei Dojima himself.
