Ōdate Uzaemon (Japanese: 大達羽 左エ門, born Benji Suwa (諏訪 辯治, Suwa Benji), December 15, 1853 – August 17, 1904) was a Japanese sumo wrestler from Tagawa, Dewa Province (now Tsuruoka, Yamagata Prefecture), Japan.

[1] Nicknamed Boujakufujin (傍若無人), meaning 'insolent', he was known both for his bad manners and outrages towards his masters, and for his wrestling skills, boosting sumo's popularity at a match given in honor of Emperor Meiji.

On 10 March 1884, at the tenran tournament held in Tokyo, he fought against Umegatani I, the "invincible yokozuna", in one of the most commented match of its time.

[5] This legendary bout took place again during the May tournament, with Umegatani in a position of dominance, recording a winning streak of 35 matches.

Nevertheless, at the height of his popularity, Ōdate was named ōzeki haridashi to mark his achievement in an official banzuke reprinted after the incident.

After mediation between the various parties, Ōdate acknowledged the assault and agreed to be demoted as punishment in the May tournament rankings of the same year.

At the time, he was also given a set of three keshō-mawashi since his patrons were betting on his continued good results and consequent promotion to the rank of yokozuna.

After his retirement as a wrestler, he took over the Chiganoura name from his last master and took charge of the latter's stable, remaining in the Tokyo Sumo Association as an elder.
