Beloved Racing Legend Behind Anime Character Passes Away Aged 31

Tsurumaru Tsuyoshi, the renowned racehorse who influenced a cherished character in the Japanese anime series Umamusume: Pretty Derby, has died aged 31. The iconic thoroughbred breathed his last on 2 August at Yoshino Farm in Japan, where he had enjoyed his retirement. According to his enduring support group, Tsurumaru Tsuyoshi was found unable to rise from his pasture and could not be saved despite medical treatment. The horse’s death prompted official tributes from the Umamusume franchise, which has constructed its premise around adapting real racehorses into animated characters whose personalities and designs reflect their actual racing careers. Tsurumaru Tsuyoshi’s character is voiced by Yoshino Aoyama and portrayed as an ambitious runner whose determination surpasses her physical capabilities—a reflection of the real horse’s promising but injury-plagued career.

A Champion’s Legacy in Two Realms

Born on 6 April 1995, Tsurumaru Tsuyoshi was the offspring of legendary racehorse Symboli Rudolf and had a distinguished career on the Japan racing scene. During his racing career, he claimed 5 victories from 11 starts, featuring the celebrated 1999 Asahi Challenge Cup and the Kyoto Daishoten—triumphs that cemented his status as a formidable competitor. However, his career path was fundamentally changed when he sustained a serious left-front leg injury during the 2000 Arima Kinen, an incident that would shape the rest of his years and profoundly influence his anime character’s portrayal of determination despite physical limitations.

The Kyoto Daishoten victory proved notably important, as it matched Tsurumaru Tsuyoshi against numerous horses who would themselves emerge as major figures in the Umamusume franchise, including Special Week, Mejiro Bright, T.M. Opera O, and Stay Gold. This intersection of real racing history and creative interpretation illustrates how Umamusume naturally integrates authentic sporting narratives into its animated universe. Tsurumaru Tsuyoshi’s move from racecourse to retirement at Yoshino Farm allowed him to spend his final decades in peaceful pasture, where he remained active and content until his last moments, exemplifying the consideration and regard extended to Japan’s retired racing legends.
