{{nihongo|'''Aoiyama Kōsuke'''|碧山亘右||born 19 June 1986 as '''Daniel Ivanov''' ({{langx|bg|Даниел Иванов}})|lead=yes}} is a Japanese former professional sumo wrestler or ''rikishi'' from Elhovo, Bulgaria. He made his professional debut in 2009, reaching the top division two years later, debuting in the November 2011 tournament. Aoiyama has won four Fighting Spirit awards, one Technique award and one ''kinboshi'' for defeating a ''yokozuna''. He was twice runner-up in a tournament. His highest rank was ''sekiwake''. Aoiyama was one of the heaviest competitors in sumo, weighing around 200 kg for most tournaments. In March 2022, he obtained Japanese citizenship.

==Early life and sumo background== After wrestling for ten years and doing amateur sumo for three, he entered the professional sumo world at the introduction of fellow countryman ''ōzeki'' Kotoōshū, becoming only the second Bulgarian ''rikishi''. He joined Tagonoura stable, run by former ''maegashira'' Kushimaumi. When asked by his coach whether he preferred mountains or rivers, he chose mountains and so was given the ''shikona'' Aoiyama, meaning "blue mountain".

==Career== ===Early career=== thumb|left|upright|Aoiyama in his debut tournament In his professional debut as Aoiyama Kiyohito in the September 2009 tournament, he won the ''jonokuchi'' championship with a perfect 7–0 record. He subsequently changed his name to Aoiyama Kōsuke for his ''jonidan'' debut in the following November tournament, which he also won with a 7–0 record followed by a playoff win against the sole Kazakhstani wrestler Kazafuzan. In the following January 2010 tournament at ''sandanme'' he finally lost his first bout, having won all of his previous 16 matches. This would be his only loss though, and his 6–1 record was enough to propel him into the ''makushita'' division in the following March tournament. He again posted a perfect record and took the ''makushita'' championship. His meteoric rise would slow starting with his next tournament however. He managed only two wins in his next ''makushita'' tournament. This was his first losing tournament. In contrast to his previous successes, he struggled somewhat for several more tournaments at this level. He eventually had enough winning tournaments in upper ''makushita'' to allow his promotion into the professional ''jūryō'' ranks for the July 2011 tournament. He was promoted to the high rank of ''jūryō'' 4 due to the high number of vacancies left by wrestlers forced to retire due to involvement in match-fixing. At this high level he only managed a 7–8 record and moved down two ranks to ''jūryō'' 6 for the following September tournament. Suffering from a herniated disc, he was forced to sit out the first two days of the tournament, but managed to make a remarkable recovery and pulled out an impressive 10–3 record for his remaining bouts of the tournament.

===''Makuuchi'' career=== Aoiyama's record was enough to allow him promotion to the top ''makuuchi'' division for November 2011. He posted an impressive 11–4 record and received a Fighting Spirit award for his efforts. He did, however, share this record with his rival, Wakakōyū having lost to him on the final day of the tournament.

In February 2012 Aoiyama's stablemaster died and Tagonoura stable was dissolved, with Aoiyama moving to the affiliated Kasugano stable. After an 8–7 score in the March tournament, he reached his highest rank to date of ''maegashira'' 6 in the May tournament, where he produced a fine 11–4 record. In the July tournament he faced all the top ranked wrestlers for the first time. Although he was 1–6 down after seven days, he recovered to clinch his ''kachi-koshi'' on the final day. In September he made his ''san'yaku'' debut at ''komusubi'', which was just 18 tournaments after his professional debut, the seventh fastest since 1958.<ref>{{cite web|url=http://sumo.goo.ne.jp/eng/hon_basho/topics/1209banzuke_besshi.pdf#page=1&view=fitH,342|title=2012 September Grand Sumo Tournament Banzuke Topics|date=September 2012|publisher=Japan Sumo Association|accessdate=7 October 2012}}{{Dead link|date=October 2019 |bot=InternetArchiveBot |fix-attempted=yes }}</ref> However, he could only win four matches. He was forced to withdraw from the November 2012 tournament on Day 9 with a knee injury. He picked up his first ''kinboshi'' or gold star for defeating ''yokozuna'' Harumafuji in September 2013.

He earned promotion to ''sekiwake'' with a strong 10–5 performance in September 2014 in which he went 4–3 against wrestlers ranked in the ''san'yaku''. He then secured a winning record in the subsequent November tournament to remain at ''sekiwake'' for the start of 2015. A 5–10 record in January 2015 saw him lose his ''san'yaku'' status was followed by another ten losses in March, but he showed some return to form to post winning records in May and July. Between September 2015 and March 2016 he recorded four consecutive 7–8 records at the top end of the ''maegashira'' rankings before a 6–9 in May.

Aoiyama responded to the less challenging schedule by producing a career-best performance in July 2017 – he entered the final day as the only wrestler left in a position to deny Hakuhō his 39th championship. He defeated ''komusubi'' Yoshikaze in his last match but was denied the chance to take part in a play-off for the ''yūshō'' when Hakuhō also won his final match.<ref>{{cite web|url=http://www.asahi.com/ajw/articles/AJ201707230023.html|title=SUMO/ Hakuho extends his career tournament title record to 39|date=23 July 2017|work=Asahi Shimbun|accessdate=28 July 2017}}</ref> Nevertheless, Aoiyama finished in second place on 13–2, winning his second Fighting Spirit prize in the process. He was promoted to ''maegashira'' 2 but was forced to miss the first week of the September 2017 tournament due to a "bone contusion" in his left knee.<ref>{{cite web|url=https://www.japantimes.co.jp/sports/2017/09/10/sumo/basho-reports/sole-competing-yokozuna-harumafuji-starts-autumn-basho-victory/#.WbZbk7lwa2w|title=Sole competing yokozuna Harumafuji starts Autumn Basho with victory|date=10 September 2017|work=The Japan Times|accessdate=11 September 2017}}</ref> He entered the tournament on Day 8 and was immediately put up against a ''yokozuna'', Harumafuji, the first time this has happened to a late entrant to a tournament since Kitanonada faced a ''yokozuna'' in his first bout back at the Nagoya tournament in 1961.<ref>{{cite web|url=https://www.nikkansports.com/battle/column/sumo/news/201709180000396.html|title=休場明け碧山いきなり横綱戦 56年ぶり|date=19 September 2017|publisher=Nikkan Sports|language=Japanese|accessdate=19 September 2017}}</ref> He also faced the rest of the ''san'yaku'' he was eligible to meet due to his high rank (though spared from facing the top-performing ''maegashira'' around him in rank) and managed only 3 wins in the 8 days he competed.

He was forced to withdraw from the November 2017 tournament on Day 3 after injuring ligaments in his right knee in a defeat to Okinoumi the previous day. However, he returned to the tournament on Day 8. Although he won two of his remaining matches this was not enough to prevent him from being demoted to ''jūryō'' for the January 2018 tournament. He scored 9–6 in this tournament, which was enough for an immediate return to ''makuuchi'', albeit at the very bottom rank of ''maegashira'' 17 East.

In March 2019 he produced his second best score in the top division to date of 12–3, and won the Fighting Spirit Prize. This performance returned him to ''komusubi'' for the May 2019 tournament, his first appearance in ''san'yaku'' since January 2015 when he was ranked at ''sekiwake''. By March 2020 he had fallen to ''maegashira'' 13, but won eleven out of his first twelve matches to be the outright tournament leader on Day 12.<ref>{{cite web|url=https://mainichi.jp/english/articles/20200319/p2g/00m/0sp/111000c|title=Sumo: Aoiyama takes sole Day 12 lead after Hakuho loses to Shodai|date=19 March 2020|work=The Mainichi|accessdate=26 March 2020|archive-date=26 March 2020|archive-url=https://web.archive.org/web/20200326194230/https://mainichi.jp/english/articles/20200319/p2g/00m/0sp/111000c|url-status=dead}}</ref> He then lost his last three bouts to Takanoshō, Hakuhō and Ishiura to finish out of the running on 11–4.

Aoiyama turned in his second ''makuuchi'' runner-up performance in the March 2021 tournament, finishing with a record of 11–4 at ''maegashira'' 12.

After being demoted to the top ''jūryō'' rank for the November 2023 tournament, Aoiyama's 8-win record was enough for him to return to the top division. At the January 2024 tournament, however, Aoiyama, wrestling as Maegashira #17, lost his first six matches. In his Day 6 loss to Kotoshōhō, wrestling as Maegashira #14, Aoiyama was forced from the ring by oshidashi and landed favoring his right leg. Although in obvious pain, Aioyama was able to return to the ring to make his bow. The next day he withdrew from the tournament, with his medical certificate indicating a suspected injury to his right ACL, a potentially career-threatening injury.<ref>{{cite web |url=https://www.nikkansports.com/battle/sumo/news/202401200000212.html|title=再入幕の碧山が「右膝前十字靱帯（じんたい）断裂の疑い」との診断書を提出して７日目から休場|date=20 January 2024|publisher=Nikkan Sports|access-date=20 January 2024|language=ja}}</ref><ref>{{cite web |url=https://www.sponichi.co.jp/sports/news/2024/01/20/kiji/20240120s00005000170000c.html|title=37歳のベテラン・碧山「右膝前十字靱帯断裂の疑い」で7日目から休場幕尻から再び十両転落へ|date=20 January 2024|publisher=Sports Nippon|access-date=20 January 2024|language=ja}}</ref><ref>{{cite web |url=https://www.youtube.com/watch?v=KxXyML1prH4|title=GRAND SUMO: Day 6 of the January 2024 Tournament - GRAND SUMO Highlights|date=20 January 2024|publisher=NHK WORLD-JAPAN|access-date=27 January 2024|language=en}}</ref><ref>{{cite web |url=https://www.youtube.com/watch?v=gGhplhWCTbY|title=GRAND SUMO: Day 7 of the January 2024 Tournament - GRAND SUMO Highlights|date=21 January 2024|publisher=NHK WORLD-JAPAN|access-date=27 January 2024|language=en}}</ref>

===Retirement=== Aoiyama dropped back down to the {{Transliteration|ja|jūryō}} division in March 2024. Following the September 2024 tournament, with demotion out of salaried status appearing likely, Aoiyama retired from professional competition.<ref>{{cite web |url=https://www.nikkansports.com/battle/sumo/news/202409240000747.html|title=元関脇碧山が引退、年寄「岩友」を襲名元大関琴欧洲に続くブルガリア出身力士|date=24 September 2024|publisher=Nikkan Sports|access-date=5 October 2024|language=ja}}</ref> At his retirement press conference Aoiyama said he was glad he became a sumo wrestler, adding that his most memorable professional bout was against then-{{Transliteration|ja|ōzeki}} Kotoshōgiku in July 2012. He remained with the Sumo Association as a coach under the elder name Iwatomo Kōsuke, which he had inherited following the passing of his stablemate, former {{Transliteration|ja|maegashira}} Kimurayama, earlier in the year.<ref>{{cite web |url=https://www.nikkansports.com/battle/sumo/news/202409260000553.html|title=元関脇碧山が引退会見…15年間の思い出は"ブルガリアの先輩"との一番「緊張して覚えてない」|date=26 September 2024|publisher=Nikkan Sports|access-date=5 October 2024|language=ja}}</ref>

Aoiyama's retirement ceremony was held in the main hall at the Ryōgoku Kokugikan on 7 September 2025. About 280 people attended the ceremony. Aoiyama was reportedly emotional throughout the event, breaking into tears when fellow Bulgarian Naruto (former {{translit|ja|ōzeki}} Kotoōshū) took his turn in snipping Aoiyama's {{translit|ja|chonmage}}.<ref>{{cite web|url=https://www.sponichi.co.jp/sports/news/2025/09/07/kiji/20250907s00005000349000c.html|title=元関脇・碧山の岩友親方が断髪式ブルガリアの先輩、鳴戸親方の労いに大粒の涙|language=ja|date=7 September 2025|publisher=Sports Nippon|access-date=7 September 2025}}</ref>

==Fighting style== Originally, Aoiyama was a ''yotsu-sumo'' specialist who preferred grabbing the opponent's ''mawashi'' and grappling rather than pushing or thrusting. However, after gaining significant weight following his Makuuchi debut, he started to predominantly use pushing, thrusting and back-step pulling attacks as this had proven extremely effective due to his upper body strength. 55% of his career victories came by way of {{Transliteration|ja|hatakikomi}} (slap down), with another 18% by {{Transliteration|ja|oshidashi}} (frontal push out).<ref>{{cite web |url=https://www.sumo.or.jp/EnSumoDataRikishi/profile/3208/|title=Aoiyama Kosuke Rikishi Profile|publisher=Japan Sumo Association|access-date=5 October 2024}}</ref>

==Personal life== Aoiyama is married to Violeta, an architect from the same area of Bulgaria as himself. They met in 2015 when both were in Bulgaria, and began living together in Japan from July 2016. The marriage was registered in August and the wedding reception was held in a Tokyo hotel in February 2017 with around 230 guests including fellow Dewanoumi group members such as Ura and Mitakeumi.<ref>{{cite web|url=https://www.nikkansports.com/battle/sumo/news/1781231.html|title=碧山が披露宴「運命」新婦トドロバさんに一目ぼれ|date=19 February 2017|publisher=Nikkan Sports|language=Japanese|accessdate=28 July 2017}}</ref><ref>{{cite web|url=http://www.hochi.co.jp/sports/sumo/20170219-OHT1T50127.html|title=碧山が披露宴！同郷の姉さん女房・トドロバさんに一目ぼれ「ホントに運命です」|date=19 February 2017|publisher=Hochi Sports|language=Japanese|accessdate=28 July 2017|archive-url=https://web.archive.org/web/20170728202702/http://www.hochi.co.jp/sports/sumo/20170219-OHT1T50127.html|archive-date=28 July 2017|url-status=dead}}</ref> In a May 2015 interview in Bulgaria, Aoiyama stated that he identifies as a Christian.<ref>{{cite web|url=https://tachiai.org/2018/03/18/reader-content-an-interview-with-aoiyama/|title=Reader Content – An Interview With Aoiyama|date=18 March 2018 |language=English|accessdate=19 March 2018}}</ref>
