The Association Members are also split into various ranks. A new retiree will have "oyakata" rank, except for former "ōzeki" and "yokozuna" who are automatically granted "Committee Member" rank. The most experienced Association members are "Committee Members". At the top are a group of elected "riji" or directors, who form the Association Board. The public face of sumo is presented by the chairman of the directors, called the "rijichō". He is effectively President of the Association. See toshiyori for more information.
