Shibatayama says he will appeal the ruling.[citation needed]
26: On the final day of the Osaka tournament, Hakuho wins his 36th yusho, and first since July 2015 in Nagoya, by sidestepping Harumafuji at the initial charge.

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.

The makushita champion is won by Satō with a perfect 7–0 record, guaranteeing his promotion to juryo next time.

After acquiring Japanese citizenship he had purchased the toshiyori or elder stock from former yokozuna Wakanohana Kanji II in May 2014, the first Mongolian born wrestler to do this (Kyokutenho had made arrangements with his stablemaster Oshima Oyakata to inherit the Oshima stock and so had no need to make a purchase.).
29: The banzuke for the September 2016 tournament is released. Both Goeido and Kotoshogiku are kadoban, or in danger of demotion from ozeki rank.

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. He is the first ozeki who was kadoban, or in danger of demotion, to take the yusho with an undefeated record and the first since Musashimaru in 1994 to claim his first championship 15–0.[16] He is also the first Japanese wrestler in exactly 20 years to zensho-yusho, the last being Takanohana. Runner-up on 13–2 is Endo, who is awarded the Technique Prize. 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. Kizenryu will be demoted back to the makushita division after he can score only 5–10 at Juryo 11 – this is the fifth time out of five that he has lasted only one tournament in juryo, a record.
31: The banzuke for the Kyushu tournament is released. Mitakeumi makes his sanyaku debut at komusubi.Hokutōfuji (formerly known as Daiki) and Ishiura make their makuuchi debuts, while Hidenoumi and Chiyotairyu return.

Former maegashiraYamaguchi [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.[17] 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.[18] The Technique Award goes to Tamawashi; it is his first ever special prize after 44 top division tournaments. He also denies Endō, who had beaten a yokozuna and three ozeki, the Outstanding Performance Award by sending him to his eighth defeat. Goeido, the winner of the previous tournament, finishes on a mediocre 9–6 while Kotoshogiku will be kadoban in January after scoring only 5–10. The juryo division championship is won by Satō.

There are two wrestlers making their sekiwake debuts – Tamawashi, who took 77 career tournaments to make the rank, and Shodai, who took just 17, the second quickest after Konishiki.[20] There are also two wrestlers making their top division debuts – Takakeishō, formerly known as Sato, and Chiyoō.[20]
