List of sumo tournament second division champions
This is a list of wrestlers who have won the sumo second division "jūryō" championship since 1909, when the current championship system was established. These official tournaments are held exclusively in Japan. The wrestler who has won the most "jūryō" championships is Masurao, with five. Wakanami, Tagaryū and Terunofuji are the only wrestlers to have won a "jūryō" championship "after" winning a top division or "makuuchi" title. The only wrestlers to win the "jūryō" championship but never earn promotion to the top division are Genbuyama (1927), Sagahikari (1957), Tochiizumi (1983), Hidenohana (1988), Daigaku  (1991), Hakuyozan (2021) and Mitoryu (2021). 1958 to present. The first table below lists the champions since the six tournament system instituted in 1958. The championship is determined by the wrestler with the highest win–loss score after fifteen bouts, held at a rate of one per day over the duration of the 15-day tournament. In the event of a tie a play-off is held between the wrestlers concerned. Names in bold mark an undefeated victory (a "zenshō-yūshō"). Figures in brackets mark the number of championships earned up to that tournament for wrestlers who won the championship  more than once.
