Keisuke Jōshita was a Japanese yakuza who was affiliated with the Yomei Alliance's Koshimizu-gumi subsidiary in Hiroshima Prefecture during the 2010s. In December 2016, he and dozens more yakuza were sent by Chairman Takeru Kurusu to prevent Kazuma Kiryu from returning to Onomichi, only for Kiryu to knock them out and fight his way to the Hirose-gumi headquarters.
