Rōga Tokiyoshi (Japanese: 狼雅 外喜義, born 2 March 1999 as Amartuvshin Amarsanaa (Russian: Амартувшин Амарсанаа) is a Russian-Mongolian professional sumo wrestler from Kyzyl, Tuva.

[5] Rōga was given his shikona, or ring name, because it is a combination of the first kanji (雅) from his master's name (former ōzeki Miyabiyama) and "wolf" (狼), a symbol of strength coming from his Mongolian roots.

In the following tournament, he remained undefeated and scored a victory against former ōzeki Terunofuji, who just made his return in competition, in a playoff to win the jonidan championship.

[11] He chose this specific first name as a tribute to the principal of Tottori Jōhoku High School and president of his sumo club, Tokiyoshi Ishiura.

[14] During the October 2023 tour, Rōga took part for the first time in the joint sekitori training sessions, normally reserved for makuuchi-ranked wrestlers.

During this training, along with maegashira Shōnannoumi and komusubi Tobizaru, he took part in the largest number of bouts of the day, wrestling 17 matches.
