Kinbōzan's first tournament was the November 2021 in Kyushu, where he won all seven of his matches and took the championship, resulting in his promotion to . At the March 2022 tournament in Osaka, he won the championship with a 7–0 sweep at the rank of 34. He would work his way up the rankings and eventually earn promotion to the second-highest professional division, , in September 2022. Following winning performances in three tournaments (including double digit wins in two of them), he was promoted to the top division in March 2023, becoming the first wrestler from Kazakhstan to do so. At a press conference following his top division promotion, Kinbōzan said that he wanted to wrestle his own style of sumo, adding he was motivated to become stronger following a recent visit to Kazakhstan to visit his mother, who was unwell.

During the of May 2023, Kinbōzan admitted that he was prone to breathing problems when put under stress or too much effort after he appeared to be genuinely uncomfortable after a session with more senior wrestlers. In the following tournament, Kinbōzan notably won his match against Takakeishō, handing him his fourth defeat on Day 10. This victory marked the first time in seven years that a ranked wrestler without a fully grown ōichōmage inflicted a defeat on an . The most recent previous occurrence of such a victory had been in July 2016 when Mitakeumi earned a victory over then- Terunofuji. Kinbōzan nevertheless finished the tournament with a score of 4–11. After two successive tournaments, in which he recorded a negative score , Kinbōzan also withdrew from the of August, reporting a sprained cervical vertebra requiring 30 days of rest, an injury which he had already contracted at the May tournament and which really limited his capabilities.

Kinbōzan remained in the division throughout 2023, however, and started 2024 at the rank of 6 east. During the twelfth day of the tournament, he suffered a knee injury in his match against Tsurugishō and had to limp back up the , telling the press afterwards that he felt severe pain even with painkillers. On the fourth day of the March 2024 tournament, Kinbōzan fell hard outside the ring in his loss to Tamawashi. He withdrew the following day, with the medical certificate stating he would need seven days of rest due to a cervical vertebra sprain. After three days of rest, he returned to competition. In the next two tournaments, Kinbōzan conceded 22 defeats, subsequently resulting in his demotion from the top division to . At the November tournament, however, he won his third professional title, taking the championship with 13 wins. The November performance put him back at the top division in January 2025 as West Maegashira #14.

At the January 2025 tournament, Kinbōzan stood out, winning nine consecutive matches from the first day of the tournament to set a personal record, also establishing himself as the only wrestler in the tournament to remain unbeaten halfway point of the competition. On Day 10, however, he suffered his first defeat at the hands of Abi, reducing to one victory the two-victory gap he had spared against the trio of wrestlers still in positions to challenge him for the title (Ōhō, Takerufuji and Chiyoshōma). He however maintained an outright one-win lead after 13 days, having defeated two opponents in Ōnosato and Kotozakura. On Day 12, he lost his match to Hōshōryū, the nephew of Asashōryū, the man who introduced him to sumo, allowing the to make a stronger bid for the title. Before the match, the former Asashōryū, who closely follows Kinbōzan's performance, allegedly called stablemaster Kise (the former Higonoumi) to encourage the wrestler, going so far as to say that Kinbōzan shouldn't lose to , referring to Hōshōryū. On the final day, Kinbōzan faced Ōhō, the latter (along with Hōshōryū) being one of two wrestlers only one defeat behind the tournament leader. Kinbōzan lost the match, forcing at the very least a playoff between the two wrestlers. Later, Hōshōryū also qualified for the title after defeating Kotozakura, with the becoming a three-way fight. Kinbōzan lost the title to Hōshōryū, who previously defeated Ōhō. For leading the competition, Kinbōzan nonetheless received his second for Fighting Spirit, however missing out on the award for Outstanding Performance after losing to Ōhō in regulation.
