His grandfather Tomio [ja], father Norihiro, and elder brother Kazuo, are all jockeys.

[1][2] When he entered the Horse Racing School in 2014 to obtain his jockey license, he was one of the smallest in the school's history, with a height of 146.7cm and weight of 34.1kg at the time, to the point that one of his teacher (who also was his uncle, Yoshikazu [ja]) recalled that "some thought he should have waited an extra year before enrolling".

[6] This was the third case in JRA history for a father and son to win the Satsuki Sho after Kunihiko and Yutaka Take and Yoichi and Yuichi Fukunaga.

[7] He was, however, unable to win the 2nd leg of the Japanese Triple Crown, the Tokyo Yushun, when Takeshi's Efforia was beaten by a nose by Yuichi's Shahryar.

[8] On October 31, 2021, Takeshi won the Tenno Sho (Autumn) with Efforia, becoming the third generation of his family to win the race.
