Shona Imamura breaks the mold: first Japanese woman to win a G1

Published on May 25, 2026 | Translated from Spanish

Jockey Shona Imamura has marked a before and after in Japanese horse racing by winning the G1 Tokyo Oaks riding Juryoku Piero. This triumph not only earns her a place in the history books but also breaks down a gender barrier that seemed firmly entrenched in Japanese horse racing. Her victory is a step forward for equity in this sport.

Shona Imamura riding Juryoku Piero during the final stretch of the G1 Tokyo Oaks, horse galloping on a tight curve, mane and tail flowing in the wind, sweat visible on the back, reins taut as the jockey leans forward with firm arms on the reins, white helmet and reflective sports glasses, brown dirt track with hoof marks, metal safety barrier in the background, grandstand with blurred Japanese flags, golden sunset light, realistic cinematic style, action frozen at peak effort, dynamic composition from a low angle showing speed and determination

The technique behind the triumph: preparation and strategy 🏆

Imamura's success was not a matter of luck. Her preparation included a detailed analysis of Juryoku Piero's performance over long distances, adjusting the race pace to avoid early fatigue. In the final stretch, she knew how to read the exact moment to accelerate, leveraging the horse's momentum and stamina. Training data and basic telemetry, applied with judgment, were the foundation of this historic victory.

Now they just need to fit her with a saddle to her measure 🐎

While the turf purists rub their eyes, Imamura shows that gender weighs no more than talent. Some will say the horse did the heavy lifting, but no one can take away the merit of having guided it without falling or losing the stirrups. Perhaps the most surprising thing is not that a woman wins, but that it took so long to happen.
