Racing career
2025: two-year-old season Juryoku Pierrot debuted on 28 September at a maiden race of 1,800m held on the dirt track of Hanshin Racecourse with Seina Imamura as her jockey. She would win that race with a three-and-a-half length lead.
The horse would then run her first group race, the JBC Nisai Yushun, but finished 7th. For the horse's final race of the season, Juryoku Pierrot was entered in to the on 20 December, but once again finished 7th.
2026: three-year-old season
On 4 January, Juryoku Pierrot was entered in to an allowance race at Kyoto Racecourse. This was her first race on turf, as all her prior races were on dirt surfaces. Despite being the least favored to win the race, she made a decent start and was well placed among the pack, and while the horse herself was in a rush, Imamura reined her in to keep her acceleration more steady. While it took time for the horse to accelerate in the home stretch, the horse managed to claim her second victory, showing her aptitude on the turf.
Her next race, the Listed , she was once again the underdog, having been the seventh favored to win the race in a field of 14 horses. Despite this, the horse was placed in the rear and took the lead from the outside on the final stretch, beating Pika Kiwi by two-and-a-half length lead and winning the race.
Juryoku Pierrot was then entered in to the Yushun Himba (Japanese Oaks), where she was the fifth most favored to win. The horse was placed in the rear of the pack, and on the final stretch, the horse pushed through a gap in the field, taking over several horses including and clinching her first group race victory. This victory was moreso a milestone for the jockey, Seina Imamura, who had not just won her first Classics race that she ever entered, but also became the first female JRA jockey to win a Group 1 race in the JRA. This race also marked the first Group 1 race victory for the horse's trainer, .
Although Juryoku Pierrot was initially entered into the Prix de l'Arc de Triomphe due to the race's deadline coming shortly after the Wasurenagusa Sho, trainer Ryo Terashima decided to not take up the entry for the race. Instead, Terashima opted to keep Juyroku Pierrot racing domestically, aiming for a run in the Shūka Shō in October prior to racing in the Queen Elizabeth II Cup in November. Terashima explained by saying, "We've decided to stay domestic this year. Her win in the Listed Wasurenagusa Sho was so impressive that we pushed from our side just to get her entered... but for this year, we felt it was better to proceed in order, first against her own generation in a G1 and then against older horses in a G1."
