Kirishima Tetsuo (霧島 鐵力), born April 24, 1996, as Byambachuluun Lkhagvasuren (Mongolian: Бямбачулуун Лхагвасүрэн) is a professional sumo wrestler from Mongolia.

He made his debut in March 2015 representing Michinoku stable under the name Kiribayama Tetsuo (霧馬山鐵雄), and reached the top makuuchi division in January 2020.

[2] He eventually moved to Ulaanbaatar and began practicing judo and bökh in a club, where he was joined later by future Ōzeki Hōshōryū.

In jonidan, he was among the wrestlers competing for the championship (yūshō), but was nevertheless beaten by Sakae, who then lost in the playoff to Hamamachi, during the last day of competition.

[6] At the time of his injury, he was also suffering from severe homesickness, but thanks to his master's efforts he hung on, motivated in particular by the prospect of returning to his homeland for a visit in the event of promotion to jūryō.

[6] In November 2017, he was competing for the makushita division championship but failed after being defeated by former jūryō wrestler Tochihiryū [ja] on the final day.

[18] Kiribayama mentions this transfer as having been particularly beneficial for him because, although he was initially anxious at the idea of training with the yokozuna, he benefited from a great deal of advice from Kakuryū.

[22] In preparation for his tournament, he showed encouraging signs in training, having defeated 4-year makuuchi-veteran Shōdai, and revealed that he would indeed serve as an assistant to Kakuryū's ring-entering ceremony.

[26][27] In March he stood at only four wins against six losses after Day 10, but won his last five matches to secure a 9–6 record and promotion to a new highest rank of Maegashira 3 for the next tournament, which was originally scheduled for May but actually took place in July.

[29] In September of the following year, Kiribayama set a personal record by scoring 4 consecutive victories for the first time in makuuchi, beating Komusubi Ichinojō in an unusually long match.

[34] In July of the same year, former yokozuna Kitanofuji published a letter to the editor in Chunichi Sports in which he congratulated Wakatakakage and Kiribayama on their match, which took place on Day 6.

[38] He stayed in the makuuchi championship race until suffering his third loss against yokozuna Terunofuji on Day 14,[39] finishing the tournament with 11 wins and his third straight Technique prize.

On 31 May 2023 Kiribayama's promotion to ōzeki was unanimously approved by the Sumo Association, and he made his formal acceptance speech when informed of the news at Michinoku stable.

[43] The medical report stated that Kirishima had bruised his right ribs and would need about three weeks of rest and treatment, but his stablemaster said at the time that he could return during the tournament.

[47] Despite his comeback, Kirishima nevertheless reached a negative score (make-koshi) when he suffered a sixth defeat to the former ōzeki Asanoyama on Day 14 of the tournament.

[48] During the 2023 September tournament, Kirishima entered as a competitor under kadoban status, having to record at least eight victories to save his ōzeki rank.

[57][58] On Day 13 he defeated the other remaining ōzeki, Hōshōryū, by nimaigeri ('ankle kicking twist down'), a technique not seen in makuuchi for ten years.

[62] After the tournament, the head of the Judging Department, Sadogatake, commented that had Kirishima won a twelfth victory by defeating Terunofuji, he would have submitted a recommendation for promotion to yokozuna.

[63] In anticipation of his master's 65th birthday in April 2024, it was announced that Michinoku stable would close after the March 2024 tournament, with its wrestlers to be distributed within the Tokitsukaze ichimon.

[64] According to sources inside the Sumo Association, Kirishima asked to be transferred to the care of former yokozuna Kakuryū in Otowayama stable.

Kirishima was demoted to sekiwake for the July tournament, where he needed to win ten matches in order to return to sumo's second-highest rank.

On the occasion of the pre-tournament training in September, during which he competed against former ōzeki Shōdai and Mitakeumi, Kirishima reassured the press by mentioning his desire to win a double-digit record in the hope of regaining his former rank, and by communicating on the recovery of his injuries.

[72] According to his Japan Sumo Association profile, Kirishima's preferred grip on his opponent's mawashi is hidari-yotsu, a right arm outside and left hand inside position.

In the run-up to his top division promotion he increased his weight to 140 kg (310 lb), giving him a more powerful attack, but he is still able to outmaneuver his opponents by his speed and footwork.
