List of sumo tournament second division champions

The first table below lists the champions since the six tournament system instituted in 1958.^[3] 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.^[4]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.
