Kotoyuki and Ikioi both won promotion to sekiwake, sumo's third-highest rank, as the Japan Sumo Association released its rankings for the Summer Grand Sumo Tournament on Monday.
Kotoyuki, 25, defeated one yokozuna and two ozeki as he went on to secure an impressive 12-3 record as first-ranked maegashira at the March tourney in Osaka. He becomes the first native of Kagawa Prefecture in 56 years to reach the rank of sekiwake. Ikioi, 29, was 10-5 as No. 4 maegashira during the basho in his native Osaka.
Kaisei, who won 11 at No. 7 maegashira, will become the first wrestler from Brazil to occupy the fourth-highest rank of komusubi. Okinoumi returns to the rank during the May 8-22 meet after three tournaments as a rank-and-file maegashira.
