Ryusei Sakai

Ryusei Sakai (Japanese: 坂井瑠星, romanized: Sakai Ryūsei, born May 31, 1997) is a Japanese jockey. He is most known as the jockey of Saudi Cup winner and Breeders' Cup Classic winner Forever Young.

Ryusei Sakai was born in 1997 to Hidemitsu Sakai [ja], a jockey and later trainer of Oi Racecourse. He enrolled in The Horse Racing School [ja] in 2013 to earn his jockey license, before graduating in 2016.

Even before graduation, he apprenticed under Yoshito Yahagi, who, like Sakai, has ties to Oi Racecourse. After being issued his jockey license, he became the Yahagi stable's official jockey.

After debuting in March 2016, Sakai won his first race with Grand Prix Accel at a maiden race held at Hanshin Racecourse on April 2, 2016. Two weeks later, he was taken out of the races for a month following a racing accident involving 4 horses including his own which resulted in him breaking one of his ribs. In spite of this, he was able to win the most races of any rookie jockies in the Ritto Training Center.

Sakai raced in Australia from late 2017 to 2018 to improve his riding skills.

The 2020 Japan Dirt Derby, with Danon Pharaoh [ja], was the first Grade I race Sakai won.

Sakai won his first JRA Grade I race with Stunning Rose in the 2022 Shuka Sho, where they defeated Stars on Earth, who was the favourite for race. Sakai then went on to win his second JRA Grade I race in a year with Dolce More [ja] when they won the Asahi Hai Futurity Stakes.

In February 2023, Sakai won the February Stakes with Lemon Pop. He and the horse would go on to win the Mile Championship Nambu Hai as well as the Champions Cup later that year. He would also win the JBC Nisai Yushun and the Zen-Nippon Nisai Yushun with Forever Young.
