Gōeidō has his best tournament as an ozeki, with a 12–3 score. Kotoshogiku, by contrast, finishes on 8–7, his yokozuna hopes dashed. The Outstanding Performance Award goes to Kotoyuki who scores 12–3 and has defeated a yokozuna and two ozeki.

25: Goeido, who clinched his first top division championship with victory over Tamawashi on the 14th day, defeats Kotoshogiku to finish with a perfect 15–0 record or zensho yusho.

Okinoumi, who defeated both yokozuna and three ozeki, gets the Outstanding Performance Award, while Takayasu is rewarded for a 10–5 performance in his sekiwake debut with the Fighting Spirit Prize. In the juryo division, Daiki takes the yusho with a 12–3 record.

Former maegashira Yamaguchi (ja) returns to the juryo division after 15 tournaments having fallen to Sandanme 65, but he is outdone by Ryūden, who returns to juryo after 24 tournaments having fallen to Jonokuchi 17, the third lowest rank ever before a successful juryo return. Oyanagi, Meisei and the Mongolian Daishoho make their juryo debuts. Oyanagi is the first sandanme tsukedashi entrant to reach juryo.

26:Kakuryu wins the Kyushu tournament, defeating ozeki Goeido to move to an unassailable two-win lead, having seen his closest rival Harumafuji lose to Hakuhō in the match immediately preceding his. He hands Goeido, who had been looking for yokozuna promotion at the start of the tournament, his fifth defeat.
27: Kakuryu defeats Harumafuji to finish with a 14–1 record. He wins his third Emperor's Cup, and second from the yokozuna rank. The runner-up is Kisenosato for the 12th time, which is a record for someone who has never won a yusho. Kisenosato also finishes with the highest number of wins for the calendar year with 69; no one else has achieved this without winning a tournament in the six basho a year era. Third place is shared by a number of wrestlers on 11–4, including Harumafuji, Hakuhō, and Shōdai, who shares the Fighting Spirit Prize with Ishiura. Isihiura had a ten bout winning streak on his top division debut, and finishes on 10–5. The Technique Award goes to Tamawashi; it is his first ever special prize after 44 top division tournaments.

There are also two wrestlers making their top division debuts – Takakeishō, formerly known as Sato, and Chiyoō.
