Kotōzan Bun'emon

was a Japanese professional sumo wrestler from Kanzaki District, Ōmi Province (now Higashiōmi, Shiga Prefecture). His highest rank was ōzeki. He is the second wrestler from Shiga Prefecture to have been promoted to this rank, having been promoted after Onogawa in 1790, 46 years earlier. As of February 1836, he is also the last wrestler from that prefecture to have achieved this feat.

Career Kotōzan was born in Yōkaichi, Shiga, a town that has since ceased to exist. He began his wrestling career in the Kyoto-based sumo association but later transferred to the Edo-based association. There, he was recruited in the Takekuma stable, under the tutelage of , hence being stablemate with Ōnomatsu Midorinosuke. Later he acquired the patronage of the Chōshū Domain. In 1827, he was given the shikona, or ring name, and made his makuuchi debut in October 1829. In 1834, he achieved the equivalent of a championship victory by winning 8 times and going undefeated. For his performance he was promoted directly to the rank of sekiwake.

After two tournaments at this rank he was promoted to ōzeki as Ōnomatsu had retired the previous year, leaving the rankings unbalanced for the first tournament of the year. After his promotion he served the Himeji Domain under his new shikona: . After a poor performance in October 1838, he was demoted from his rank but regained it for the following tournament. He remained ozeki for 10 tournaments, giving the image of a stable, solid wrestler, rarely losing to lower-ranked wrestlers but failing to shine against higher-ranked wrestlers either. Kotōzan died on 25 June 1858.

Top division record The actual time the tournaments were held during the year in this period often varied. Championships for the best record in a tournament were not recognized or awarded before the 1909 summer tournament and the above championships that are labelled "unofficial" are historically conferred.
