News

January

Tochinoshin was the surprise winner of the January tournament

• 6: The highest ranked referee, Shikimori Inosuke, is reported in the Japanese media to have apologized for sexually harassing a junior referee in a hotel in Okinawa Prefecture on December 16 last year, while drunk. ^[2]
• 9: The three current yokozuna, Hakuhō, Kakuryū and Kisenosato, perform the traditional New Year dohyo-iri ceremony at the Meiji Shrine. ^[3]
• 14: The Sumo Association suspend Shikimori Inosuke for three tournaments. He has already submitted his resignation, but it will not take effect until after the suspension ends in May 2018. ^[4] With the other top referee title (Kimura Shonosuke) currently vacant, this will be the first time since the March 1994 tournament that neither of the head referees (tate-gyōji) will be available. ^[4]
• 11: Kakuryū and Kisenosato, both of whom have missed some or all of the preceding four tournaments, each confirm that they will enter the forthcoming Hatsu basho. ^[5]
• 22: Egyptian juryo division wrestler Ōsunaarashi withdraws from the tournament after reports emerge that he was involved in a rear-end motor collision at the Yamanouchi, Nagano ski resort town on January 3. ^[6] Osunaarashi apparently defied the Sumo Association's ban on wrestlers driving cars, and also did not have a valid licence. He initially told police that his pregnant wife was driving and he switched seats to protect her, but back-tracked when confronted with security video evidence.
• 25: A lawsuit against Kasugano Oyakata and a former member of Kasugano stable who had been convicted of assault, is publicly revealed for the first time. The victim, another former wrestler from the stable, alleges that Kasugano failed to prevent the attack and delayed medical treatment. ^[7]
• 27: The championship is won by maegashira Tochinoshin, who defeats Shōhōzan to move to an unassailable two-win lead of 13 wins against just one loss. It is the first championship by a maegashira since Kyokutenhō in 2012. ^[8]
• 28: On the final day of the Hatsu Basho, Tochinoshin wins again to finish on 14–1, two wins ahead of ōzeki Takayasu on 12–3. ^[9] Kakuryū, the only yokozuna to complete the tournament, stops a run of four straight defeats by beating ōzeki Gōeidō to finish with a respectable 11–4 record on his comeback. ^[9] Tochinoshin receives special prizes for Outstanding Performance and Technique to go with his first Emperor's Cup, while the Fighting Spirit Award is shared between top division debutants Ryūden and Abi, who both score 10–5. ^[9] The jūryō division championship is won by Myōgiryū for the third time, after a playoff with Hidenoumi. Retiring this tournament are former maegashira Shōtenrō, Kitataiki and Sōtairyū  [ ja ].
• 31: Seven promotions to the jūryō division for the March tournament in Osaka are announced. There are two newcomers, Enhō (who ties the record for fastest postwar promotion to jūryō at six tournaments) ^[10] and Takayoshitoshi (meaning he and Takagenji have become the first identical twins to both be ranked as sekitori) ^[11] while Yago, Terutsuyoshi, Shimanoumi, Tobizaru and Akiseyama return.

The 40th Shikimori Inosuke was suspended in January

February

• 1: Nishiiwa Oyakata, the former sekiwake Wakanosato, branches out from Tagonoura stable and establishes his own Nishiiwa stable, taking two low-ranked wrestlers with him from the parent stable.
• 2: Elections to the 10 man Board of Directors of the Japan Sumo Association are held. Isegahama Oyakata (ex-Asahifuji) and Nishonoseki Oyakata (ex-Wakashimazu) do not run for re-election. The eleven candidates running are Kasugano, Sakaigawa, Dewanoumi and Yamahibiki from Dewanoumi ichimon, Oguruma and Shibatayama from Nishonoseki ichimon, Kagamiyama from Tokitsukaze ichimon, Hakkaku from Takasago ichimon, Takashima from Isegahama ichimon, and Takanohana and Ōnomatsu from Takanohana ichimon. The man to miss out is Takanohana, who receives only two votes from the 101 elders who participated. He had been dismissed from the board at the end of December following his lack of co-operation with the Sumo Association's investigation into the Harumafuji assault on Takanoiwa last year. ^[12]
• 3: Sōtairyū's danpatsu-shiki or official retirement ceremony is held at the Ryōgoku Kokugikan with around 300 guests. Sōtairyū is leaving the sumo world.
• 4: Former sekiwake Asasekiryū, who retired last May, has his danpatsu-shiki at the Kokugikan. He is now officially Nishikijima Oyakata.
• 8: An outside committee led by a former prosecutor general, Keiichi Tadaki, is formed and will interview all 900 wrestlers in the Sumo Association in response to a series of incidents since Harumafuji's retirement. Tadaki says, "Our goal is the preservation of sumo. It is important to grasp the reality." ^[13]
• 11: The 42nd Fuji TV Grand Sumo Tournament takes place at the Kokugikan. ^[14] A knock-out format exhibition with a 2,500,000 yen prize for the yusho, it is won by Tochinoshin who defeats Ikioi, Hakuhō (who he has never beaten in official competition in 25 attempts), Hokutofuji, Okinoumi and finally Tamawashi.

March

• 9: Ōsunaarashi is asked to retire by the Sumo Association over his involvement in the vehicle collision and driving without a license. He had been fined 500,000 yen ($4700) by a court over the incident in Nagano Prefecture in January. ^[15] Ōsunaarashi agrees to the request. ^[16]
• 18: New juryo Takayoshitoshi withdraws from the Osaka tournament after admitting he struck a junior wrestler who was acting as a personal attendant several times in the dressing room after his Day 8 bout. ^[17] Takayoshitoshi was reportedly angry that the attendant had not informed him when he was due to enter the arena, making him late for his match. ^[18]
• 23: Takanohana indicates that he will drop his legal complaint against the Sumo Association and admits responsibility for Takayoshitoshi's behavior, as his stablemaster. ^[19]
• 25: On the final day Takayasu defeats Kakuryu after a re-match to finish one win behind the yokozuna on 12–3. ^[20] Kakuryu had clinched his fourth championship the previous day, ^[21] and his only other defeat was to Tochinoshin, who wins the Outstanding Performance Award. ^[20] Brazilian Kaisei is a surprise joint runner-up with Takayasu on 12–3 and wins the Fighting Spirit Prize. ^[20] The Technique Award goes to Endō, who for the first time gets a winning record at the top maegashira rank. The jūryō championship is won by Sadanoumi after a playoff with Akiseyama while veteran Higonojō  [ ja ] takes the makushita title. Retiring is Kotomisen  [ ja ], who spent two tournaments in jūryō in 2013.
• 29: Takanohana is demoted two further ranks in the Sumo Association hierarchy, to the lowest rank of toshiyori. Takayoshitoshi is suspended from the next tournament in May. ^[22]

April

• 1: Futagoyama Oyakata, the former ozeki Miyabiyama, branches out from Fujishima stable and establishes his own Futagoyama stable, taking five low ranked wrestlers with him. ^[23]
• The spring regional tour visits the following locations: ^[24]
  • 1: Ise Shrine Honozumo, Mie Prefecture
  • 2: Nakatsugawa, Gifu Prefecture
  • 3: Sakai, Osaka Prefecture
  • 4: Maizuru, Kyoto Prefecture. Chairman Hakkaku issues an apology after a referee ordered women off the dohyo when they were trying to administer first aid to the mayor of Maizuru, who had just collapsed with a subarachnoid hemorrhage while giving a speech. Hakkaku says, "In a situation that could have been life-threatening it was an inappropriate response." ^[25]
  • 5: Himeji, Hyogo Prefecture
  • 6: Takarazuka, Hyogo Prefecture. The female mayor of Takarazuka, who had to stand next to the dohyo instead of entering it at the exhibition, meets with the Sumo Association's public relations chief Shibatayama on April 18, and asks that they reconsider the longstanding "no women" policy. ^[26]
  • 7: Kariya, Aichi Prefecture
  • 8: Shizuoka, Shizuoka Prefecture
  • 9: Kakegawa, Shizuoka Prefecture
  • 10: Ina, Nagano Prefecture

• 30: The banzuke for the upcoming Natsu tournament in May is released. Kyokutaisei makes his makuuchi debut, while Sadanoumi, Takekaze and Aminishiki return. Endō makes his sanyaku debut at komusubi. ^[28] There are two new promotions to jūryō, Takadagawa stable's Hakuyozan  [ ja ] and former Toyo University amateur Wakatakakage, who becomes the third sandanme tsukedashi entrant to reach sekitori status. ^[29] Asabenkei returns to jūryō for the first time since September 2016.

May

• 11: Former maegashira Ōiwato  [ ja ] announces his retirement. ^[30] Last year he became the oldest winner of the makushita division championship in the six tournaments a year era. He plans to work for an electronic recycling company in Kanagawa Prefecture.
• 11: The Tagonoura stable duo of Kisenosato and Takayasu both announce they will miss the beginning of the May tournament. ^[31] For Kisenosato it will be the seventh straight basho he has failed to complete, equaling the unwanted record of most yokozuna absences post-1958 set by Takanohana who sat out seven full tournaments in 2001 and 2002. Takanohana did make a successful comeback with a 12–3 record in September 2002 and tells Kisenosato, "He should take his time to heal. As long as he's fighting he should be in top shape. The key is not to rush." ^[31] Kisenosato's stablemaster Tagonoura says doctors have told the yokozuna he should stay away from intense training for a month, and will "fight for his life" when he next competes in July. ^[31] Takayasu injured his left upper arm in training earlier in the week but still hopes to enter the tournament at some point. ^[31]
• 14: Former maegashira Amūru of Russia, who has fallen to makushita, announces his retirement. ^[32]
• 21: The only ōzeki competing in the May tournament, Gōeidō, pulls out with an ankle injury, making this the first time since 1949 that the only two ōzeki on the banzuke have withdrawn from a tournament. ^[33]
• 27: The championship is decided in the final bout of the tournament, with Kakuryū defeating Hakuhō to clinch his second successive yūshō with a 14–1 record, avoiding the need for a playoff with Tochinoshin, who finishes on 13–2. Tochinoshin wins the Technique and Fighting Spirit Prizes, and with 37 wins over the last three tournaments is assured of ōzeki promotion. Also sharing the Fighting Spirit Prize are Kyokutaisei, who scores 10–5 in his makuuchi debut, and Chiyonokuni, who produces his best ever record of 12–3.
