It is also the lowest rank where achieving a "kachi-koshi" (winning record in a tournament) is no longer sufficient to guarantee promotion to a higher rank. Promotion to the next highest rank, "sekiwake", depends on either a space being available, which is quite common, or having at least 11 wins in the previous tournament if no normal "sekiwake" slot is available. This general requirement can be seen by the promotion of Tochiōzan to a third "sekiwake" slot for March 2014 with 11 wins when the other two "sekiwake" had winning records, while Tochinoshin was not promoted with 10 wins for November 2015 in a similar situation.
