The precursor to a full-fledged organization began in the Edo period with sumo bouts that were often held to raise funds for new construction or repair of bridges, temples, shrines and other public buildings. "Shōgun" Tokugawa Ieyasu specifically, wanted "street" sumo prohibited and determined sumo should only be held for charitable purposes, and it was known as "kanjin" sumo. The wrestlers were also paid with extra revenue from these events. This is when the first organized competitions with paid wrestlers began. Written rankings, known as "banzuke" were introduced from 1761 and this is where the committee that organized these rankings began to emerge as an organization. In this time, sumo came to be called "Ōzumō", "the big sumo" or professional sumo.
