medial collateral ligament and
medial meniscus of his left knee, could have cost him a year's absence from the ring had he opted for surgery. However, Kotonowaka decided to opt for
regenerative surgery and obtained mixed results at the following tournaments as a result of his therapy. In January 2022 Kotonowaka won eleven matches from 14, and was awarded the Fighting Spirit prize for the second time. In March Kotonowaka was in contention for the championship on the final day for the second straight tournament, but lost to

Oginishiki Yasutoshi at the Nagoya tournament in
1997. He retained his rankings for the March tournament. In the March tournament Kotonowaka secured a record, which included a win over eventual championship winner
Kiribayama. During the July tournament of the same year, Kotonowaka scored several significant victories, including against former
Mitakeumi and
Shōdai, as well as
promotion seekers,
Daieishō. On Day 7, he even defeated one of the tournament leaders,
Nishikigi, ending his streak of 14 straight wins. On the tenth day, Kotonowaka inflicted defeat on another rank contender,
Hōshōryū. This victory was particularly significant for Kotonowaka, who had only beaten Hōshōryū once in eleven matches since the two joined the division. In a
letter to the editor published in
Sankei Sports, former
Musōyama commented with satisfaction on Kotonowaka's wrestling style, deeming it worthy of the rank of . For his performances during the tournament, Kotonowaka was promised a fourth
award for Fighting Spirit, which was nonetheless conditional on an eleventh victory. On the final day of the tournament, Kotonowaka won his match against
Ryūden and was awarded the prize. Since he achieved double figures in a rank, and was the first in this category to reach 10 wins during the July tournament, Kotonowaka commented on his satisfaction at having seriously strengthened his case for promotion to the rank of , the highest rank held by his father and master (former
Kotonowaka Terumasa) after having stagnated at the rank of for 4 consecutive tournaments. He also commented on his ambition to be promoted to , in order to revive and inherit the , or ring name, of his maternal grandfather, former
Kotozakura, to whom he had made this promise. Kotonowaka's promotion to was made official with the release of the September tournament rankings on 28 August 2023. He became Sadogatake stable's first since

Kotozakura. Since Kotonowaka has obtained a solid base to start
a run towards the rank of , it was announced before the September tournament that his matches would be sponsored by the management and entertainment company
LDH. During the November 2023 tournament, Kotonowaka made his mark with a third consecutive victory on the third day of the championship, using the rare ('backward twisting overarm throw'); a technique that had not been used in the division for 13 years. He continued his tournament with a good performance, recording a winning record on Day 10 for the eighth tournament in a row. On the thirteenth day of the tournament Kotonowaka recorded a fourth defeat against
Ryūden, automatically eliminating him from the title race and ended his hopes of promotion to at the end of the tournament. Despite having been knocked out of the title race, Kotonowaka played a part in the final outcome of the tournament with a victory over
Atamifuji, who needed a win to possibly trigger a playoff for the championship. As this victory was a prerequisite for the
Fighting Spirit award, Kotonowaka won the prize for the fifth time in his career. Kotonowaka finished 2023 with winning records at the ranks in all six of his tournaments. His father
Sadogatake, speaking as the head of the Sumo Association's judging department, added that promotion is at stake for Kotonowaka at the tournament in January 2024. Kotonowaka performed well in the first half of the tournament, although he also recorded a defeat on Day 6 against
Wakamotoharu. Kotonowaka maintained his position as one of the tournament's leading wrestlers (with
Ōnosato and
Ōnoshō) by recording a on Day 9 against fellow
Daieishō, securing an eighth consecutive tournament in the ranks of . On the tenth day, Kotonowaka faced and defeated

Terunofuji, reportedly leaving him in a state of extreme frustration after the match and placing him
ex-aequo with the and
Kirishima for the title race. However, he managed to bounce back the following day by inflicting defeat on promotion-seeking
Kirishima, with the title to be decided on the final day. In addition, he won his final match against
Tobizaru, claiming a thirteenth victory necessary to reach the milestone traditionally required for promotion to the rank of (33 victories in 3 tournaments). With this victory he also qualified for a playoff against
Terunofuji to claim both his first championship and the Outstanding Performance award. After the tournament, a disappointed and tearful Kotonowaka was nevertheless praised by
Terunofuji when the latter gave the traditional post-victory public interview, saying he hoped Kotonowaka would rise to the supreme rank of .
Promotion to Immediately after the end of the January 2024 tournament it was announced that the Judging Department of the Sumo Association (led by Kotonowaka's father Sadogatake) had submitted a request to Chairman
Hakkaku to promote Kotonowaka to the rank of . It was reported after the tournament that Kotonowaka was expected to keep his (ring name) for a while to honor his father, whose highest rank in competition was , before adopting the name of his late grandfather
Kotozakura. The Sumo Association approved Kotonowaka's promotion on 31 January 2024, making him the first from
Chiba Prefecture since the promotion of
Matsunobori after the Autumn tournament in 1955. Director Hanakago (former
Daijuyama) officially delivered the news to the new along with Naruto (former
Kotoōshū), a sumo judge who had competed professionally as a member of
Sadogatake stable. In his customary acceptance speech, Kotonowaka said: "With a feeling of gratitude I will devote myself to the way of sumo in order to live up to the title of ." He also confirmed that he would retain the Kotonowaka name for the next tournament in March, before changing to
Kotozakura on the May 2024 . His father Sadogatake shared his expectations that his son would ultimately reach sumo's top rank of , saying that he had "one more step to climb." During the March tournament, Kotonowaka remained in a position of potential contention for a championship win until Day 13, when he was defeated by fellow-
Takakeishō, ending his chances of winning the tournament. On day 14, he nevertheless took away his chances of winning the tournament from fellow- Hōshōryū by beating him by (frontal crush out).
Kotozakura legacy After the conclusion of the March tournament Kotonowaka, who secured 10 wins in his debut, submitted his official paperwork to change his ring name to Kotozakura starting in May. The name change became official on the banzuke for the May tournament, making the new Kotozakura the first wrestler to bear this name in 50 years. Interestingly, the name change was published on the on 30 April 2024 as , changing the spelling of the first name borne by his grandfather (琴櫻 傑將) by reversing its kanji with the same pronunciation. The new Kotozakura explained his choice by declaring that the current form of his first name inspired good omens. Having practiced writing his new to make autographs, however, Kotozakura declared that dedicating the kanji for was too complicated. Although he had made the choice to keep the traditional kanji for
cherry blossom () in his name, he would dedicate with the simplified kanji () for simplicity, which his grandfather had also chosen to do.
First top-division championship and race During the 2024 November tournament, Kotozakura and two other were the top wrestlers competing with the withdrawal of
Terunofuji. Kotozakura won 13 of his first 14 matches and entered the final day of top-division competition to face fellow
Hōshōryū, who also had 13 wins. In the final and deciding match Kotozakura countered
Hōshōryū's overarm throw attempt, winning by (slap down) to take his first career
Emperor's Cup and second overall professional sumo
championship. By coincidence, Kotozakura won his first top-division title in his fifth tournament as an at 27 years of age, the same as his late grandfather
Kotozakura I, who won under the exact same circumstances in July 1968. Kotozakura also finished 2024 with 66 wins, the most of any wrestler in the top division. On Day 13 he lost to then-tournament leader
Kinbōzan for his eighth defeat, which meant that the former candidate would need a winning record at the next tournament to
retain his rank. In February Kotozakura made visits to nearby
Tokitsukaze stable for training sessions, in what was reported to be a rare move for him to do prior to the release of the March tournament
rankings. Although Kotozakura was able to earn records to get rid of his status, he had been unable to reproduce strong scores since winning his first championship in 2024. He also expressed his frustration at having failed to conquer the highest rank in professional sumo earlier that year, consecutively losing the title race to
Hōshōryū and
Ōnosato. As member of the
Nishonoseki clan, Kotozakura even took part in the ceremonies related to Ōnosato's promotion. Near the end of the September 2025 tournament Kotozakura withdrew due to right knee ligament damage, according to his medical certificate, which stated that he would need three weeks of recovery time. Though Kotozakura had already secured a winning record in the tournament, his withdrawal was the fourth in his career, and his first at the rank. At the March 2026 tournament, Kotozakura stood out for defeating Yokozuna
Hōshōryū on Day 14, eliminating the Yokozuna from the championship race. The next day, he defeated
Kirishima, who had secured the tournament championship the previous day. This meant that Kotozakura finished the tournament with a record, the first time he had ended with double-digit victories since he won the championship in November 2024. ==Fighting style==
