Japanese female jockey Seina Imamura breaks barrier with historic G1 victory
Imamura rides Juuryoku Piero to triumph at the Oaks, marking a significant shift in the landscape of Japanese horse racing.
Seina Imamura has secured a place in the history of Japanese horse racing, becoming the first female jockey to win a Grade 1 (G1) race. The milestone was achieved on 24 May 2026 at the Oaks G1 event, where she guided the horse Juuryoku Piero to victory.
According to NHK News Japan, Juuryoku Piero entered the competition as the fifth favourite. The win represents the highest level of achievement in the sport, with G1 races designated as the premier tier of competition. Imamura’s performance on the track has thus concluded a long-standing barrier for women in the discipline.
The Oaks G1 is a significant fixture in the racing calendar, drawing attention for its competitive field and high stakes. By securing the title aboard Juuryoku Piero, Imamura has demonstrated a capability to perform at the elite level of the sport, challenging previous gender norms within the Japanese racing industry.
This victory is not merely a singular athletic achievement but a structural shift in the profession. For decades, the top tiers of Japanese horse racing have been dominated by male jockeys. Imamura’s success provides a verified precedent for female competitors aiming for the highest honours in the sport.
The confirmation of this win by NHK News Japan underscores the institutional recognition of the event. As the first Japanese woman to claim a G1 title, Imamura’s achievement sets a new benchmark for future generations of jockeys and highlights the evolving dynamics of governance and participation in Japanese sports.
