News

January

• 12: At the Hatsu basho in Tokyo, ozeki Kaio wins his 808th top makuuchi division bout by throwing down former ozeki Chiyotaikai, breaking the record set by Chiyonofuji in 1991.^[2] It is Chiyotaikai's third defeat in the first three days, leaving his hopes of getting promoted back to ozeki by scoring 10–5 or better virtually gone.
• 13: Chiyotaikai announces his retirement from sumo.^[3] He will stay in the sumo world as a coach at Kokonoe stable, under the name Sanoyama Oyakata.
• 19: The 65th Yokozuna Takanohana is told to leave the Nishonoseki ichimon or group of stables after announcing that he will run for a position on the board of Directors of the Japan Sumo Association against the two officially sanctioned candidates for the group.^[4] Six of Takanohana's supporters, Otake (the former Takatoriki), Futagoyama (the former Dairyu), Otowayama (the former Takanonami), Tokiwayama (the former Takamisugi), Onomatsu (the former Masurao) and Magaki (the former Wakanohana II), are also kicked out of the ichimon.
• 23: Yokozuna Asashoryu wins his 25th yūshō or championship by defeating ozeki Harumafuji by shitatenage or underarm throw. His score of 13 wins against just one loss means he cannot be caught by any of his rivals. He is now alone in third place on the all-time list of top division championships, behind only Taiho and Chiyonofuji.^[5]
• 24: On the final day of competition, Hakuho defeats Asashoryu to finish runner-up to his yokozuna rival on 12–3. Having lost only four regulation bouts in the whole of 2009, his three losses in this tournament (to Baruto, Harumafuji and Kaio) are the most he has suffered since May 2008. Baruto also finishes on 12–3, and wins his first Outstanding Performance Award. Had he achieved kachi-koshi, maegashira Goeido would have received a share of that prize as he defeated Asashoryu earlier in the tournament, but he loses to Aminishiki who receives the Technique Award. The third man on 12–3 is Toyohibiki, who wins the Fighting Spirit Prize. The jūryō division championship is won by Georgian Gagamaru. Two former maegashira who have been fighting in the third makushita division for some time, Tamarikido and Daimanazuru, both announce their retirements. Tamarikido is staying in sumo as Araiso Oyakata, but Daimanazuru is leaving.
• 25: Asashoryu is warned over his conduct by Sumo Association head Musashigawa after reportedly punching one of his managers during a drunken night out after Day 6 of the basho.^[6]
• 27: The promotions to the jūryō division for the Haru tournament in March are announced. There are three newcomers: Masuraumi [ja] (formerly Kurosawa, his new shikona is based on that of his stablemaster, the former Masurao) and Daido (formerly Nakanishi), both from the Onomatsu stable, and Sadanofuji from the Sakaigawa stable. In addition, Tokushinho from Kise stable returns to the jūryō division after two tournaments away.
• 28: The weekly magazine Shukan Shincho hits the newsstands and claims that the man allegedly assaulted by Asashoryu was not his manager but another acquaintance in charge of a dance club where Asashoryu was drinking, who received a broken nose. Amid suggestions of a cover-up, the Sumo Association demand an explanation.^[7]
• 30: Musashigawa says that Asashoryu has reached an amicable settlement with the man he allegedly attacked, meaning the yokozuna will not face police charges, although the chairman has not seen written confirmation. He confirms that any punishment will not be decided on until the next board meeting on February 4.^[8]
• 30: The danpatsu-shiki or retirement ceremony of former maegashira Otsukasa takes place at the Kokugikan.^[9]
• 31: The retirement ceremony of former maegashira Ushiomaru is held at the Kokugikan.^[9] Asashoryu performs the dohyo-iri and takes a snip of Ushiomaru's hair.

Independent candidate Takanohana is elected with the necessary ten votes, replacing the 62-year-old Oshima who can only manage eight.

Musashigawa retains his position as chairman.
• 2: Ajigawa Oyakata, the former Kobo, admits that he was one of the oyakata who switched his vote from Oshima to Takanohana, and says he will resign from the Sumo Association. He is however later persuaded to stay.
• 2: Tomozuna Oyakata, the former Kaiki, who is heading a committee looking into the Asashoryu affair, says he has spoken to the yokozuna's personal manager (who has said he is standing down to take responsibility for his misleading statement that he was the one attacked) and his driver, who denied reports that Asashoryu punched the man or made threats against him. "The driver did not see Asashoryu slug the man. He said it was nothing like what was reported."^[10]
• 4: Following a meeting with the Directors of the Sumo Association, Asashoryu and his stablemaster Takasago announce the yokozuna's retirement from sumo. Asashoryu said, "I have caused a lot of trouble for so many people. I decided to step down to bring this to a closure."^[11] Musashigawa told reporters, "He felt compelled to resign for misconduct that was inexcusable, and the board accepted. I want to apologise to sumo fans and the injured person. We will work to ensure this kind of incident never happens again."^[12]

• 12: Two more wrestlers, jūryō ranked Matsutani and sandanme ranked Wakarikido, both of the Matsugane stable, are found to have gambled on baseball. Neither wrestler came forward during the Sumo Association's investigations and consequently they competed in the July tournament while others were suspended. The investigative committee will decide on disciplinary action on September 6.^[51]

• 24: Former makushita wrestler Daitensho [ja], a Mongolian who has Japanese citizenship, sues his former stablemaster Takashima Oyakata, alleging that he was forced to retire against his will the previous month.

• 26: Hakuho's dominance continues as he wraps up his sixteenth yūshō by defeating Harumafuji. His 62nd consecutive win gives him his fourth zensho-yūshō in a row and eighth overall, tying the record jointly held by Futabayama and Taiho. Runner-up is rank-and-filer Takekaze on 12–3 who receives the Fighting Spirit prize, shared with stablemate Yoshikaze who finishes on 11–4.

• 15: On the second day of the Kyushu tournament, maegashira Kisenosato defeats Hakuhō, stopping his winning run at 63. Despite falling short of Futabayama's all-time mark of 69, Sumo Association chairman Hanaregoma called Hakuho's streak "a very creditable record."

He also finishes the year on 86 wins out of a possible 90, equalling the record he set last year. Toyonoshima, who followed up his 14–1 jūryō yusho with the same number of wins this time out, receives special prizes for Technique and Fighting Spirit. Fellow returnee Goeido, who finished on 12–3, does not receive a prize. Instead Kisenosato who scored 10–5, gets the Outstanding Performance Award for his defeat of Hakuho. Kaio finishes on 12–3 (his best performance for six years), one win ahead of fellow ozeki Baruto. The jūryō championship is won by the Brazilian Kaisei in a four-way playoff after he, Toyohibiki, Tochinowaka and debutant Takayasu all finish on 11–4.

His retirement leaves Kaio as the oldest sekitori.
• 21: The banzuke for the January 2011 tournament in Tokyo is released. Kaio is the top ozeki for the first time since July 2007.
