Takeshi Yokoyama

Takeshi Yokoyama (横山武史; born December 22, 1998) is a Japanese jockey.

He graduated from the school in 2017 and obtained his jockey license.

On April 26, 2020, Takeshi won his first graded race when he won the Flora Stakes with.

Later that year, Takeshi won the Kikka Sho with Titleholder. 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.

On October 31, 2021, Takeshi won the Tenno Sho (Autumn) with Efforia, becoming the third generation of his family to win the race. Later that year, Takeshi and Efforia also won the Arima Kinen, and also won the Hopeful Stakes with Killer Ability.
