News

January

• 23: Yokozuna Hakuhō wins his 33rd Yūshō and breaks the all-time tournament win record held by Taihō since 1971.^[2] He beats ōzeki Kisenosato in a re-match after their first bout was judged too close to call. It is his thirteenth straight win and with no one else scoring better than ten wins, he has wrapped up the championship with two days to spare.
• 24: Hakuhō wins his 800th bout in the top division with a defeat of his fellow yokozuna Harumafuji,^[3] only the fourth man after Kitanoumi, Chiyonofuji and Kaiō to reach this landmark.
• 25: The final day of the tournament is a sell-out, meaning every day of a basho held in the Ryōgoku Kokugikan has sold out for the first time in 18 years.^[4] Hakuhō completes his 11th zenshō yūshō or perfect score (another record) with a win over Kakuryū, meaning exactly one third of his championships have come without suffering a single defeat. There are a record 61 sponsor's envelopes placed on his bout. Trailing in a long way behind on 11–4 are Harumafuji, Kisenosato, and maegashira Tokushōryū who share runner-up honours. There is just one special prize awarded, to Terunofuji who defeated two ōzeki and is the only man ranked between sekiwake and maegashira 5 to get a majority of wins. He is certain to be promoted to the sanyaku ranks next tournament. Gōeidō preserves his ōzeki rank by beating Kotoshōgiku, who had also been threatened with demotion. The jūryō division championship goes to Kitataiki for the second time. Retiring after this tournament are former komusubi Homasho, maegashira Tochinowaka and Towanoyama, and jūryō Senshō.
• 27: Hakuhō receives criticism after telling a post-tournament press conference that he should not have been made to redo his match with Kisenosato as "looking at the video, even a child could see (that I won)."^[5] His stablemaster Miyagino apologizes on his behalf.

February

• 1: The fifth Hakuho Cup is held at the Kokugikan and shown live on Niconico. The event features elementary school and junior high school sumo teams from Japan, Mongolia, South Korea, China, Bulgaria, Estonia, the US and Australia.

• 8: The 39th Fuji TV Grand Sumo knockout tournament is held at the Kokugikan. Harumafuji wins, defeating Kisenosato in the final. Gagamaru wins the juryo event.

• 18: Veteran Aminishiki withdraws through injury.
• 21: Hakuhō wins his 34th tournament, and his sixth in a row, by beating Harumafuji on the final day.

• 24: Terunofuji follows up his superb performance in March by winning his first top division tournament championship. His victory over Aoiyama on the final day, coupled with Hakuho's surprise defeat to Harumafuji, means Hakuho's streak of six consecutive championships comes to an end. Terunofuji's score of 12–3 is actually not as good as the previous tournament, but no-one else scored better than 11–4. Terunofuji also wins the Fighting Spirit Award, and is virtually guaranteed promotion to ozeki. There are no other sansho winners. The juryo title goes to Kagamio. In the sandanme division, 44-year-old {{Interlanguage link multi|Dewanosato Hideyuki|ja|3=出羽の郷秀之|lt=Dewanosato}}, who spent just one tournament in juryo exactly ten years previously, announces his retirement after an exceptional 29 years and 174 basho in sumo.
