Robuchen and jockey Kohei Matsuyama won the 93rd Japan Derby on Sunday at Tokyo Racecourse [1], [2].
The victory marks a rare feat in Japanese racing, as Robuchen becomes only the 25th horse to achieve the classic double by winning both the Satsuki Sho and the Japan Derby [1]. This achievement establishes the horse as the leader of a competitive generation consisting of 7,944 three-year-old horses [1].
The race took place over a 2,400-meter turf course [2], [3]. Robuchen entered the event in top form following the Satsuki Sho victory, with the horse having secured two G1 wins in total [4].
For jockey Kohei Matsuyama, the win ended a long pursuit of the prestigious title. This victory came in his 11th attempt at the Japan Derby [1]. Matsuyama said earlier this month that he was watching how the horse would perform on the CW course [5].
Trainer Haruki Sugiyama attributed the horse's readiness to its time spent at the grazing lands, saying, "放牧先でしっかりと取ってもらった" [6]. The combination of Sugiyama's conditioning and Matsuyama's ride enabled the horse to maintain its dominance over the 2,400-meter distance [2], [3].
Robuchen's performance at Tokyo Racecourse cements its status as a generational talent. By securing the second leg of the classic double, the horse has now outpaced the vast majority of its peers in the current three-year-old crop [1].
“Robuchen becomes only the 25th horse to achieve the classic double”
The classic double is one of the most difficult achievements in Japanese thoroughbred racing, requiring a horse to possess both the speed for the Satsuki Sho and the stamina for the 2,400-meter Derby. Robuchen's victory not only validates the horse's versatility but also provides a career-defining milestone for Kohei Matsuyama, who had spent a decade attempting to win the race.
