Uma profile
Yaeno Muteki
Yaeno Muteki is the sort of Umamusume who seems to arrive with a straight back, a sharpened gaze, and the air of someone who takes every contest seriously. A Senior Division student from Ritto Dormitory, she presents herself as a warrior-like runner who prizes dignity as much as speed. Her own introduction says it plainly: as a practitioner of the Kongo Yaegaki style, she is always seeking honorable opponents and wants to compete fair and square.
That sense of discipline defines her image—rugged on the surface, but deeply committed to respect, effort, and the clean thrill of a worthy race.
That sternness is only part of the picture, though, and Yaeno becomes more charming the longer you look. She calls herself Watashi and addresses her mentor as Trainer-dono, a formal touch that suits her old-school seriousness perfectly. Yet the details around her reveal someone more human and unexpectedly endearing: she is good at sewing and mopping floors, struggles with sitting formally and with eating while walking, and when she gets upset, it apparently shows in her handwriting. Even her body language gives her away now and then—her ears turn a little red when she hears a cute voice. For someone who tries to stand so solidly composed, those small cracks in the armor only make her more memorable.
Physically, Yaeno Muteki cuts a compact, balanced figure at 159 cm, with measurements listed as 78-54-81 cm and a shoe size of 24.0 cm. Her recorded weight note is simply “No change.” She is voiced by Ayumi Hinohara, whose performance supports that mix of firmness and earnestness in her character. There is also a wonderfully vivid bit of trivia attached to her: her tail is strong enough to knock away incoming projectiles. It is exactly the kind of detail that makes her feel less like a purely stoic archetype and more like a full-fledged Uma Musume with a slightly fearsome physical presence.
Her connections also reinforce her competitive spirit. No Reason is listed as her roommate, while Bamboo Memory, Oguri Cap, Super Creek, Sakura Chiyono O, and Mejiro Ardan are all noted among her related names and rivals. Even without dressing those ties up into more than the record supports, the pattern is clear: Yaeno is framed by competition, comparison, and the search for opponents worthy of her ideals. She is not a flamboyant showboat; her drama comes from resolve. She wants the race to mean something.

His earnings reached ¥518.30 million in JRA figures, with JBIS listing total earnings of ¥524,227,500.

He was by Yamaninsky, a son of the great Nijinsky, and out of Tsurumi Star, by Yellow God. That pedigree placed him in an interesting blend of international classic bloodlines and Japanese breeding, and his later recognition as the 1990 JRA Best Horse by Home-bred Sire underlined the importance of his background. The family also included siblings such as Muteki Surpass, Mayano Princess and Yaeno Shori.
On the track, Yaeno Muteki built his reputation as a high-class performer at middle distances, with his biggest breakthrough coming in 1988 when he won the Satsuki Sho, one of the Japanese Triple Crown races. That same year he also added the Kyoto Shimbun Hai and Naruo Kinen, confirming that his Classic success was no fluke and that he belonged among the best of his generation.
He remained a durable and effective older horse after his three-year-old season. In 1989 he captured the Sankei Osaka Hai, and in 1990 he achieved another elite victory in the Tenno Sho (Autumn), one of Japan’s most prestigious races for older horses. That campaign brought him the JRA Award for Best Horse by Home-bred Sire, a distinction that reflected both his own quality and the significance of his sire line within Japanese racing.
Yaeno Muteki retired with a profile that combined Classic success, longevity at the top level, and importance as a representative of domestic breeding. He later died on 28 March 2014. Though not the most globally famous Japanese horse of his era, he remains a respected name in the historical record: a Satsuki Sho winner who trained on, stayed sound enough to compete across several seasons, and added a Tenno Sho to secure his place in Japan’s racing story.
