The Japanese Derby, officially known as the Tokyo Yushun, is one of Japan's most prestigious horse races. Held annually in late May at Tokyo Racecourse, it is open to three-year-old thoroughbreds and covers a distance of 2,400 meters. The race attracts top horses, trainers, and jockeys, making it a highlight of the Japanese horse racing calendar. Established in 1932, the Japanese Derby is part of the Japan Racing Association (JRA) series and is considered a key event in the road to the Triple Crown of Japanese horse racing. Winning this race is a significant achievement, often leading to increased breeding value for the horses involved.
