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. 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. 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. 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. He then lost his last three bouts to Takanoshō, Hakuhō and Ishiura to finish out of the running on 11–4. He was however given his first Technique Prize. Aoiyama turned in his second makuuchi runner-up performance in the March 2021 tournament, finishing with a record of 11–4 at maegashira 12. He was awarded his fourth kantō-shō (Fighting Spirit Prize) for his efforts. He withdrew from the following tournament in May due to lower back pain. In May 2022 Aoiyama won his first six
