[3] He was talked of, alongside Masunoyama, as a candidate for the first wrestler born in the Heisei era to reach the sekitori status when he produced a 5–2 score at the rank of makushita 15 in November 2009.

[2] However his progress then stalled with two consecutive make-koshi, and he suffered a concussion after falling from the dohyō in a match against Takanoiwa in March 2010, and had to be carried off in a wheelchair.

[7] He scored ten wins in his top division debut and shared the Fighting Spirit prize with fellow newcomer Abi.

In September 2018, Ryūden was the fastest maegashira-ranked wrestler to reach the positive kachi-koshi balance with a win over Shōhōzan.

[9] For this feat and his 10 wins in total, he was nominated for the Fighting Spirit Award, but was shelved because he did not reach the majority of the attending committee members votes.

With 79 tournaments elapsed since entering professional sumo, Ryūden is also the 10th slowest wrestler to reach the san'yaku ranks.

[11] Entering the July 2019 tournament at his highest rank, Ryūden recorded an initial defeat to yokozuna Kakuryū,[12] but bounced back to claim back-to-back victories over ōzeki Takayasu and Tochinoshin.

[16][17] After an investigation by the compliance department of the Sumo Association, it was found that on 25 different occasions between 12 March 2020, and 20 January 2021, Ryūden had gone out with several women, breaking the rules on unnecessary trips.

[21] Thanks to his championship victory, he was promoted to makushita 5 and during this period he was competing to win a second tournament in a row but was beaten on the final day by Gōnoyama (then called Nishikawa).

[24] On his return to sumo's top division, he finished just a few victories behind the tournament winner (junyūshō), maegashira Tamawashi, notably achieving a seven-match winning streak.

In February 2019, Ryūden announced his engagement to his partner, a nurse named Mai Fukumaru, after a four-year relationship.
