[2] Despite the fact that they are in different stables, Tobizaru will not face him in competition as Japan Sumo Association rules prevent close relatives from being matched against each other outside of playoff bouts.

He studied economics at Nihon University and was a member of their sumo team, but weighing only around 110 kg and having to sit out a year with an ankle injury he did not manage to win any major amateur titles.

[5] In his makuuchi debut he came close to becoming the first wrestler since Ryōgoku Kajinosuke II in 1914 to win the championship in his first top division tournament, needing to beat Shōdai on the final day to force a playoff, but he was defeated and finished with a 11–4 record.

[7] Due to his strong showing in the September 2022 tournament, finishing with ten wins, Tobizaru was promoted to komusubi for November, his debut in the junior san'yaku ranks.

[13] In response to the growing criticism, Nikkan Sports commented in an editorial that the judges had probably awarded the victory to Hōshōryū because he had shown himself to be dominant in the match and Tobizaru was not in a position to continue fighting.

[17][18] Tobizaru however suffered an eighth defeat, when he lost his fourteenth match against former ōzeki Takayasu, effectively relegating him for the November tournament.

When questioned by the Sumo Association's investigation unit, Tobizaru denied the accusations and announced his intention to sue the tabloids that had spread the rumours for defamation.

[25] Tobizaru is below the average size for an elite sumo wrestler, being the second lightest sekitori when he reached jūryō in 2017, and he stands just 175 cm (5 ft 9 in) tall.

[27] Tobizaru style is fast-paced, and he regularly sidestepped at the initial charge when in jūryō, but in his makuuchi debut made a conscious effort to fight more on the offensive.
