Sixth-ranked maegashira Meisei claimed a resounding win over Terunofuji on May 22, joining the lone grand champion and No. 14 Asanoyama in the leading pack after nine days of action at the Summer Grand Sumo Tournament.
Lone yokozuna Terunofuji remained unbeaten on May 18 at the Summer Grand Sumo Tournament, but sole ozeki Takakeisho suffered his second upset loss on Day 5 at Tokyo's Ryogoku Kokugikan.
Returning lone yokozuna Terunofuji and ozeki promotion-bidding sekiwake Kiribayama both won on May 14 as the Summer Grand Sumo Tournament began with no upsets among top-ranked wrestlers.
Mongolian-born Kiribayama was placed top among the four sekiwake in the May 14-28 Summer Grand Sumo Tournament rankings announced on May 1, as the March champion bids for promotion to the second-highest rank of ozeki.
New sekiwake Kiribayama came from behind to win the Spring Grand Sumo Tournament on March 26, beating overnight leader Daieisho in the final regulation bout and again in a sudden-death tiebreaker.
