*A yūshō system giving the wrestler with the best tournament record a prize was introduced by the Mainichi newspaper in the second half of 1909, and this was officially integrated by the JSA in 1926. All tournaments predating the second tournament of 1909 did not recognize or award a championship. As a consequence of this, yokozuna Hitachiyama had seven pre-1909 mathematical "championship" equivalents that are uncounted here, and yokozuna Tachiyama had two.
**Asashio would later become Minanogawa Tōzō
