Early career

Hokutofuji was a high school yokozuna at Saitama Sakae High School (also the alma mater of Gōeidō) and won multiple major amateur champions before his senior year at Nippon Sport Science University. If he had entered professional sumo in either of those years he would have started as a makushita tsukedashi and skipped the lower divisions, but his parents wanted him to complete his education. So instead he made his debut in March 2015 at the maezumō level. He was unable to compete under his family name of Nakamura as that was already taken by Nakamura Oyakata (former sekiwake Kotonishiki), so instead he used his given name, Daiki. He rose up the ranks quickly, winning the yūshō or tournament championships in the jonidan and sandanme divisions with perfect 7-0 records. He became a sekitori upon reaching the jūryō division in July 2016, and he won the jūryō championship in September with a 12–3 record, which saw him promoted to the top makuuchi division. His rise to the top division in ten tournaments was the second fastest of modern times behind that of Jōkōryū who achieved the feat in nine tournaments in 2012. At this point he changed his shikona from Daiki to Hokutofuji, which was derived from the shikona of his stablemaster, former yokozuna Hokutoumi, and Hokutoumi's own stablemaster, former yokozuna Kitanofuji.

Makuuchi career

Hokutofuji came through with a solid 9–6 record in his top division debut and recorded 9 wins again in January 2017. In March he recorded the first make-koshi (losing record) of his career, but a 10–5 result in May saw him move up the rankings. In the July 2017 tournament he earned a kinboshi or gold star in his first ever match against a yokozuna, defeating Kakuryū,^[1] and finished with eight wins. On Day 4 of the September tournament he beat yokozuna Harumafuji to claim his second kinboshi.^[2] He was a runner-up to Hakuhō in the November 2017 tournament with an 11–4 record, and was awarded his first special prize, for Technique. He also defeated yokozuna Kisenosato in this tournament, earning his third kinboshi in his last three tournaments.^[3] In January 2018 he won a fourth straight kinboshi by defeating Hakuhō on Day 3,^[4] but he finished the tournament with only four wins against eleven losses. In the May 2018 tournament he suffered a concussion during a false start at the tachi-ai in his match against Ryūden on Day 10.^[5] He withdrew from the rest of the tournament. Returning in July ranked at the bottom of the division at maegashira 16, he secured a winning record.^[6]

In March 2019 he made his sanyaku debut at komusubi rank. He was the third komusubi from Saitama Prefecture after Wakabayama in September 1951 and Wakachichibu in March 1959. He is also the fourth komusubi from Hakkaku stable following Kaiho, Hokutoriki and Okinoumi.^[7] In September 2019 he picked up his sixth kinboshi by defeating Hakuhō on the opening day.^[8] Following this victory he lost his next six matches to fall to 1-6 but made an impressive recovery by winning his final 8 matches to finish the tournament at 9-6. He returned to the komusubi rank in November, one of four komusubi in that tournament, but fell just short of a majority of wins with a 7–8 record. Back in the maegashira ranks in January 2020 he earned his seventh kinboshi by defeating Kakuryū on Day 3.^[9] He also beat both ōzeki, and finished the tournament with eleven wins and his second Technique Prize.^[10] He returned to the komusubi rank in March, and defeated Kakuryū again on Day 2,^[11] but finished the tournament with a 4–11 record. He has remained in the maegashira ranks since July 2020, and has alternated between winning and losing records for 16 straight tournaments up until May 2022. He was forced to withdraw from the July tournament on the final day due to COVID-19 protocols, although he already had a losing record by that point. In September he was the tournament leader after winning his first nine matches,^[12] but he lost five of his last six matches to finish with a 10–5 record.^[13]

In July 2023, Hokutofuji had a solid tournament, winning his twelfth match against ōzeki-promotion seekers, Hōshōryū.^[14] He also topped the rankings after the thirteenth day of the tournament, following a victory over maegashira Endō. Commenting on his performance, he expressed his desire to break his record for makuuchi wins with a twelfth victory over one of the other wrestlers competing for the title, the newly promoted Hakuōhō.^[15] In September, Hokutofuji revealed he injured his right calf during a training session prior to the sixth day of the tournament.^[16]

During the September tournament, Hokutofuji put in a remarkable performance on the first three days. At the rank of maegashira 1, he faced the three ōzeki of the time (Takakeishō, Kirishima and Hōshōryū) and won each of these matches.^[17] In an editorial for Sports Nippon, Tamanoi-oyakata praised Hokutofuji and his "veteran skills" and for overcoming his neck and knee injuries.^[18] This performance marks only the fifth time since the beginning of the Shōwa era that a wrestler not ranked in san'yaku has won three consecutive victories over ōzeki-ranked wrestlers.^[19] He was promoted to komusubi for the fourth time in November 2023, but won just 5 out of 15 matches and was demoted back to the maegashira ranks.

On Day 8 of the January 2024 tournament, Hokutofuji landed awkwardly at the end of his match against Hōshōryū. After he was helped up by attendants, Hokutofuji was taken to the Kokugikan's medical clinic in a wheelchair. He withdrew from the tournament the next day, with his medical certificate noting a right knee contusion requiring about two weeks of treatment.^[20]
