) is a Mongolian-born former professional sumo wrestler (rikishi) from Ulaanbaatar, Mongolia. Making his debut in March 2001, he reached the top makuuchi division in May 2004. In May 2007 at age 22, he became the second native of Mongolia, the fourth non-Japanese, and 69th overall rikishi to be promoted to the highest rank in sumo, yokozuna. With a record 45 total championships (yūshō) at the top makuuchi division, he is widely considered to be the greatest sumo wrestler of all time. He acquired Japanese citizenship in 2019.
In 2009, he broke the record for the most wins in a calendar year, winning 86 out of 90 bouts, and repeated this feat with the same record again in 2010 when he established the second longest winning streak in sumo history. He also holds the record for the most undefeated tournament championships at sixteen, which is eight more than any other sumo wrestler in history.
He was the only active yokozuna from 2010, following the retirement of his rival and fellow Mongolian Asashōryū, until 2012 with the promotion of fellow Mongolian Harumafuji. In March 2021, he became the only active yokozuna once again following the retirement of his rival and fellow Mongolian Kakuryū until the promotion of fellow Mongolian Terunofuji four months later.
In January 2015, he broke Taihō's long-standing record by winning his 33rd top division championship, the most in the history of sumo. He holds the records for most wins in the top division, achieved in May 2016, and most career wins, achieved in July 2017. He was the longest-serving yokozuna of all-time, having surpassed Haguroyama's record in 2019, and fought his 1000th bout as a yokozuna in July 2020.
Hakuhō retired from professional sumo at the end of September 2021, closing out a 20-year career in the sport. Sumo commentator John Gunning noted that Hakuhō left an unmatchable legacy, while Washington Post columnist Stephen Stromberg called him "possibly the most accomplished figure in any sport, ever".
Hakuhō departed from the Japan Sumo Association in June 2025, after he was relieved from overseeing his stable in early 2024 following an investigation into assaults on the part of his wrestler Hokuseihō.
Early life and sumo background Like many of his countrymen in professional sumo, Hakuhō belongs to a family in the Mongolian wrestling tradition. His father Jigjidiin Mönkhbat won a silver medal in freestyle wrestling at the 1968 Summer Olympics, his country's first ever Olympic medal, and held the highest ranking in Mongolian wrestling, "Darkhan Avarga" (meaning "Undisputed Champion"), which is the Mongolian equivalent of yokozuna. Davaajargal did not however have any formal training in Mongolian wrestling himself, as his father wished him to try other sports, and he concentrated on basketball as a child instead. However, at an early age he would be seen reading sumo magazines, and when his father asked him why he liked sumo so much, he responded by saying he wanted to be as big as a sumo wrestler one day. At that time he was considered below average in size.
He went to Japan in October 2000 when he was fifteen years old, invited by pioneering Mongolian wrestler Kyokushūzan. Because he weighed only , no sumo training stable (heya) was prepared to accept him. Hearing this, Kyokushūzan asked heya master Miyagino-oyakata to intercede, and Davaajargal was accepted to Miyagino stable on the last day of his two-month stay in Japan, 24 December 2000. He was given the ring name (shikona) Hakuhō, with haku meaning "white" and hō, meaning the Chinese mythological bird Peng. His shikona also emulates that of former yokozuna Taihō, whose rivalry with Kashiwado became known as the Hakuhō era.
Hakuhō made his professional debut at the March tournament (honbasho) in Osaka in 2001 despite having no previous wrestling experience. His weight increased steadily as he rose in the ranks reaching the second highest jūryō division in January 2004, and the top makuuchi division in May of the same year. In his very first top-division tournament, he scored twelve wins against three losses and was awarded a special prize (sanshō) for Fighting Spirit. He also enjoyed great success in subsequent tournaments, winning a gold star (kinboshi) for defeating yokozuna Asashōryū in November 2004 while still at the lowest makuuchi rank of maegashira. This tournament also saw him finish as runner-up for the first time. He achieved a rapid promotion to the rank of komusubi in January 2005 and sekiwake only one tournament later. His progress was delayed by an injury which forced him to take leave (zen-kyu) from the Nagoya tournament in 2005.
His ōzeki promotion came in March 2006 after a 13–2 record, which included a playoff for the championship (which he lost to Asashōryū) and also earned him two special prizes for Outstanding Performance and Technique. This gave him a three tournament record of 35 wins against ten losses. His promotion was confirmed just a few weeks after his twenty-first birthday, making him the fourth youngest wrestler to reach ōzeki in modern sumo history.
Ōzeki At his first tournament as ōzeki in May 2006, with Asashōryū absent, Hakuhō won his first championship (yūshō) with a 14–1 record, defeating Miyabiyama in another playoff. After another strong performance (13–2) in July, in which he finished as runner-up to Asashōryū and defeated him on the final day, Hakuhō was denied promotion to yokozuna, despite the Japan Sumo Association's chairman Kitanoumi saying before the tournament that he would be considered if he posted 13 wins. Hakuhō told an interviewer that he had expected to be promoted. An uncharacteristically poor 8–7 showing in September put an end to any immediate promotion hopes. An injury sustained in training prevented him from participating in the November tournament, putting him at risk for demotion (kadoban) in January 2007, when he scored a respectable ten wins on his return to the ring.
Promotion to yokozuna
In March 2007 Hakuhō won his second championship in Osaka and a third championship in the very next tournament in May, with a perfect 15–0 (zenshō) record. Winning two consecutive championships satisfies the de facto requirements for promotion to the top rank in sumo. On the day following the tournament, the Yokozuna Deliberation Council unanimously recommended his promotion to yokozuna which was formally announced by the Japan Sumo Association on 30 May 2007. He had become yokozuna at the age of 22 years and two months – only Kitanoumi and Taihō had been younger when they were promoted. He performed his inaugural ring-entering ceremony (dohyō-iri) at the Meiji Shrine (in the lesser-used Shiranui style) on 1 June. He performed the ceremony at the Kokugikan during Kyokushūzan's retirement ceremony (danpatsu-shiki) on 2 June.
Yokozuna
2007 Hakuhō's first tournament as a yokozuna was in July 2007. His 25 match winning streak was brought to an end by Kotomitsuki on the 10th day, and further losses to Kotoōshū and Chiyotaikai put him out of contention for the title. He finished the tournament with an 11–4 record.
Hakuhō's first tournament championship as a yokozuna came in September 2007 with a 13–2 record, triumphing over Chiyotaikai on the last day. His second title as a yokozuna, and fifth overall, came in the following tournament in November with a 12–3 score. He lost to Kotomitsuki on the final day but the championship had already been decided earlier in the day when his only challenger Chiyotaikai pulled out through injury. His yokozuna rival Asashōryū missed both these tournaments through suspension.
2008 In the January 2008 tournament, he faced the returning Asashōryū on the final day with both wrestlers having a 13–1 score. In a bout lasting nearly a minute, Hakuhō defeated Asashōryū, winning his 6th championship with a 14–1 record. In the March 2008 tournament the two yokozuna met once again to decide the title and this time Asashōryū got his revenge, with Hakuhō finishing as runner-up.
In the May 2008 tournament, he won his first nine consecutive bouts. On the 10th day, however, he lost to Ama for the fourth time in their last five meetings, injuring his ankle in the process. Subsequent losses to Kotoōshū (the eventual winner of the tournament) and Kotomitsuki put him out of contention for the championship. He finished on 11–4, losing to Asashōryū on the final day in a match that sparked scandal after the two yokozuna nearly came to blows when Asashōryū gave Hakuhō an extra shove after the bout was over. Both wrestlers were given a warning over their conduct by the Japan Sumo Association.
In July 2008, with Asashōryū pulling out through injury he won his seventh championship without a serious challenge, securing victory by the 13th day: the first time this had been achieved since January 2005. He finished the tournament unbeaten; his second zenshō-yūshō. Although he lost on day five of the September tournament, he still dominated all other opponents and secured another championship on the 14th day. He finished the tournament with a 14–1 record.
In the November tournament Hakuhō was once again the sole yokozuna participating. He lost his opening bout to Aminishiki and his 12th day bout to Ama. Both Hakuhō and Ama finished with a 13–2 record and the eventual play-off was won by Hakuhō, handing him his fourth yūshō of the season and ninth in total.
2009
In the January 2009 tournament Hakuhō defeated Asashōryū on the final day in their first meeting since May, handing his fellow yokozuna his first defeat of the tournament and leaving both men with identical 14–1 records. Hakuhō was however beaten in the subsequent playoff. Hakuhō defeated Asashōryū again in the March tournament, this time capping off an undefeated 15–0 championship, his third zenshō-yūshō and his tenth championship overall.
In May he extended his winning run to 33 regulation bouts, the best since Asashōryū's 35 in 2004, until he was defeated by Kotoōshū on Day 14. He recovered to beat Asashōryū on Day 15 to finish at 14–1, but he lost the playoff bout to Harumafuji who claimed his first championship.
In July he won his eleventh championship, finishing one win ahead of Kotoōshū with another 14–1 score. He almost pulled off his twelfth championship in the following September tournament. One win behind Asashōryū for most of the tournament after giving away his first kinboshi in a year (to Shōtenrō) he forced a playoff by beating his rival on the final day, but then lost in the succeeding playoff bout. This was a very similar scenario to his loss to Asashōryū in the preceding January tournament. Regardless of this loss, he still managed to become the first makuuchi wrestler ever to win fourteen or more bouts in five consecutive tournaments. He also became the first wrestler ever to lose three makuuchi playoffs in one year. After the tournament he was diagnosed with ligament damage in his left elbow; however surgery was not required.
On 28 November, the fourteenth day of the Kyūshū basho, he clinched his twelfth tournament championship and broke Asashōryū's 2005 record for most bouts won in a calendar year, which had stood at 84. He defeated Asashōryū the following day to secure his fourth career zenshō-yūshō and set his 2009 record total at 86 wins. This was also his fourteenth consecutive yūshō or jun-yūshō (winner or runner-up) performance, another record.
2010 In the opening tournament of the year Hakuhō's 30 bout winning streak was ended by Baruto on Day 7, and he suffered consecutive losses to ozeki Harumafuji and Kaiō on Days 12 and 13 to concede the title to Asashōryū by Day 14. He gained some consolation by beating his yokozuna rival for the seventh straight time in regulation bouts on the final day to finish the tournament on 12–3.
