2022: Three-year-old season
Stunning Rose started the season off with the Kobushi Sho held on February 13, where she was the most favored to win. She placed herself in the middle of the pack for most of the race before making a pass, catching front-runner Seiun Hades [ja] and winning by a head.[4] At the Flower Cup held on March 21, she was able to keep her pace among the pack, before passing Nishino Love Wink just before the finishing line and scoring her first graded race victory.[5] She was the last crop of her sire, King Kamehameha, and with that victory he achieved producing a grade winning crop in all fourteen generations.[6]
After winning the Flower Cup, she did not head to the Oka Sho, but headed straight to the Oaks following a brief break.[7] As she headed straight to the Oaks without running the Oka Sho, she was only the 10th most favored to win at that race. However, she ran a good position and overtook the lead on the final stretch, only to be passed at the last second by Stars on Earth, finishing second.[8]
After taking a break for the summer, she was entered in to the Shion Stakes, which is a trial race for the Shuka Sho. Although she gained 14 kilograms since her last race, she was nonetheless the most favored to win, with the parimutuel odds of her at 2.8. She won the race after swiftly coming through the pack, earning her a slot in the Shuka Sho.[9]
At the Shuka Sho, she was placed in the middle of the pack, and moved up as the pack entered the final stretch. She managed to shake off Double Crown winner Stars on Earth and Namur [ja], who finished third at the Oaks, and won her first Grade I race. This was also the first Grade I win for her jockey, Ryusei Sakai, and the first time her trainer Takano won a Grade I race since Lei Papale in the previous year's Osaka Hai, and the first time winning the Shuka Sho since Shonan Pandora in 2014.
On November 13, she was entered in to the Queen Elizabeth II Cup as her last race of the year. She was the second most favored to win behind Daring Tact. She made a decent start and was among the middle pack, but failed to keep up beyond that and finished at 14th place.[10]
2024: Five-year-old season
Stunning Rose returned to racing after a 10-month break at the Osaka Hai in March. She was able to make headway for most of the race, but lost momentum and finished at 8th place.[13] She then went on to finish 9th at the Victoria Mile and 6th at the Queen Stakes.
On November 10, Stunning Rose was entered in to the Queen Elizabeth II Cup, the same race where she lost at 14th place. She ran most of the race at around fourth place, before catching up with the front runners at around the fourth corner. On the final stretch she overtook and kept the momentum, winning her second Grade I race since the Shuka Sho.[14]
