- She had a record of three wins and two third place finishes in dirt races since her debut.
In all three of those races, she had performed well despite a slow start, so her connections had a high regard for her abilities.
For her next race, her connections chose the Tulip Sho, a trial race for the Oka Sho. - In the Tulip Sho, it was the first turf race for her.
She got off to a late start, stumbled as she accelerated, and her jockey, Shigefumi Kumazawa, fell off.
She was unable to run in the first classic race, Oka Sho. - She then went on to finish 2nd and 1st with new jockey Junichiro Oka, allowing her to run in the Oaks.
However, since Junichiro Oka had won less than 31 races in total, he was not allowed to ride her in G1 races.
She was again paired with Kumazawa Shigefumi for the Oaks. - In the Yushun Himba (Japanese Oaks), she was 10th favorite.
She got off to a slow start, but gradually moved up through the pack.
She took the lead about 100 meters before the finish line and won by 1+1/2 lengths.
It was the first G1 win for her and her jockey, Shigefumi Kumazawa.
It was the day of Kumazawa’s first race at Tokyo Racecourse, and he was said to have lost his way.
(A similar story was told about Dai Yusaku on the day of his Arima Kinen.) - She then raced the summer races without a break and had good results.
Perhaps because of this, she broke a bone while adjusting for the Queen Elizabeth Ⅱ Cup in the autumn.
She won a race on her return from a broken bone, but retired without a good result in grade races.
About her birth
- Her sire, Buzen Daio, did not have a good racing career, and although he was registered as a stallion, his role was that of a stallion brought near a mare to see whether the mare is in heat or to stimulate it into estrus.
- Her dam, Sweet Dream, had a habit of kicking, even when she was in heat.
This meant that she could have an accident with a high value stallion.
She had once been mated to a promising stallion, Mogami, but he had become infertile.
She was mated to Buzen Daio, a low value stallion with little financial consequences if he was involved in an accident, to practice mating. - Cosmo Dream’s success increased the value of her sire, Buzen Daio, and her dam, Sweet Dream, but no other horses were successful.
