Seina Imamura Makes History with First Female JRA Grade 1 Victory
Japanese jockey Seina Imamura has made racing history by becoming the first female jockey to win a Grade 1 race under the Japan Racing Association (JRA).
The landmark victory came aboard Juryoku Pierrot in the Yushun Himba - one of Japan’s most prestigious races for three-year-old fillies, held over 2,400 metres at Tokyo Racecourse.
At just 22 years old, Imamura guided the fifth-fancied filly to victory in a time of 2:25.06, securing a breakthrough moment not only for herself, but for female representation within Japanese racing.
“Jockeys lose most of their races,
so this feels like a dream,”
Imamura said following the win.
Born in Shiga Prefecture, Imamura made her professional debut in 2022 and quickly established herself as one of the sport’s emerging talents, winning notable races during her rookie season. Her rise, however, has not been without setbacks. Injuries and difficult periods tested her progress, but she spoke openly after Sunday’s victory about the importance of patience and persistence.
“I’d be really happy if Juryoku Pierrot and I inspired many people with dreams and hope,” she said.
Before Imamura’s breakthrough, female jockeys competing under the JRA had collectively contested eight Grade 1 races without securing a win at the highest level. Her success therefore, represents a significant cultural and sporting milestone within one of the world’s most traditional racing jurisdictions.
“I don’t think I would have believed a year ago that something like this would happen,” she added. “Life is full of unexpected events.”
Japanese racing has historically remained heavily male-dominated, particularly at elite level, making Imamura’s achievement all the more significant. While women have continued to increase their presence globally within racing, landmark victories in major jurisdictions remain rare and often carry influence far beyond the result itself.
Imamura’s win in the Japanese Oaks reflects not only individual talent, but a broader shift taking place within international racing - one where female riders are increasingly challenging long-standing barriers at the very top of the sport.
“I hope to enjoy my time riding horses and show people the good things about horse racing,” she said.
For Japanese racing, the result marks a historic first. For the wider industry, it is another reminder that progress within the sport continues to be shaped by those willing to challenge what has previously seemed unreachable.
