Early career

Initially wrestling under his real surname Ihara (庵原), Midorifuji began his first real tournament in jonokuchi in November 2016. At the end of the 7 official days of competition, he and his stablemate Nishikifuji (then named Ogasawara) were both unbeaten and tied for the championship. Nishikifuji nevertheless won the championship by yoritaoshi.^[6][7] For the January 2017 tournament, Midorifuji received his current shikona, or ring name, to evoke, with the kanji 翠 (meaning green), jade, a stone that shines brighter when polished, in the same way that a wrestler becomes better through practice.^[8] During this tournament, Midorifuji and Nishikifuji faced off again in the championship playoff. Although Midorifuji prepared his fight with his senior, and then ōzeki, Terunofuji, he lost again to Nishikifuji.^[9] In January 2020 ranked at makushita 2 he earned promotion to the sekitori ranks for the first time with a 5-2 record.^[4] This promotion made him the first sumo wrestler from Shizuoka Prefecture to become a new jūryō since Tochihiryū [ja] in the March tournament of 2013,^[4] and the second sekitori from Yaizu, after Katayama in 2004.^[2] However, he still weighed barely 100 kg (220 lb) and turned in a losing 7-8 record in his jūryō division debut. He managed to remain in the division, and in September 2020 he produced an 11-4 record. In the following November 2020 tournament, Midorifuji notably scored a victory over Jōkōryū on Day 13 using the rare kimarite (winning technique) zubuneri ("head pivot throw"), a first at this level of competition since Kyokushūzan used it in January 1996.^[10] In total, Midorifuji also used the katasukashi kimarite ("under-shoulder swing down") 4 times during the tournament.^[11] Midorifuji ended with a 10-5 score, enough to earn him his first career championship (yūshō) after a playoff win over Kyokushūhō.^[12] This championship victory also saw him promoted to sumo's top division, makuuchi, for the next tournament in January 2021.^[11]

Makuuchi career

Midorifuji was the fifth top division wrestler from Shizuoka Prefecture since World War II and the first since Sagatsukasa in 2010.^[13] Ahead of his debut he said he hoped to emulate fellow small wrestlers Enhō and Terutsuyoshi.^[14] In his top division debut in January 2021 Midorifuji scored nine wins against six losses and won the ginō-shō or Technique prize, with a win over Tobizaru on Day 15.^[15] Midorifuji is only the seventh wrestler to receive this award in his makuuchi debut and the first since Tochinohana in May 2000.^[16] Five of his nine wins were by the kimarite of katasukashi, or under-shoulder swing down.^[17] On the subject of the use of this kimarite, many commentators have begun to refer to this technique as Midorifuji's speciality, referring to it in particular as Denkanohōtō (伝家の宝刀), meaning 'family heirloom' or 'family tradition', since it was also used extensively by Midorifuji's master, Isegahama (former yokozuna Asahifuji), and by Midorifuji's senior in his stable, Aminishiki, who is also described as a technical genius.^[1] Midorifuji said he was happy to have received the award, but regretted that he had not managed ten wins.^[18]

This performance saw him promoted to the rank of maegasahira 10 for the March 2021 tournament, where he produced a 5–10 record. He withdrew from the May 2021 tournament due to a herniated disc in his back, requiring two months of treatment.^[19] Upon his comeback in July 2021, ranked in the jūryō division, he could only manage a 6-9 record. In March 2022 a 12–3 score saw him promoted back to the top division for the May tournament.^[20]
During the March 2023 tournament, Midorifuji first achieved his best performance in makuuchi by winning five bouts in a row.^[21] He then went to lead the honbasho, recording ten wins in ten matches and securing a comfortable lead against Daieishō, the wrestler closest to his score, with two wins ahead of the former.^[22] However, he fell on the eleventh day with a defeat against Wakamotoharu, and then on the twelfth day against Wakatakakage.^[23] On the fourteenth day, Daieishō handed him his fourth consecutive defeat, which took Midorifuji out of the title race.^[24] Midorifuji was listed as a potential recipient of a Fighting Spirit award on Day 15, but it was contingent on an eleventh win. Midorifuji lost to Shōdai and did not receive the award.^[25] Commenting on his performance at the tournament, Midorifuji expressed his joy at having made it this far in the title race and considered the tournament a good experience.^[24]

At the July tournament, Midorifuji won against the new ōzeki Kirishima, in a demanding match of about two minutes, marked by a rare "mawashi matta" (まわし待った), or mawashi break, a pause during which the gyōji reattaches a wrestler's mawashi.^[26]

During the preparations for the September 2023 tournament, Midorifuji was ranked as the lightest makuuchi wrestler, and was also the lightest wrestler ranked as sekitori, ex-æquo with Kihō.^[27]

During the November 2023 tournament, Midorifuji had a notable match with Hokuseihō on day seven; the match being between the lightest and tallest wrestler in the division. The match also received attention after lasting a total of 6 minutes 40 seconds, and being marked by a very rare mizu-iri (water break), an event that had not happened in makuuchi for 8 years, since day fourteen of the March 2015 tournament during the match between Terunofuji and Ichinojō.^[28]
