Beloved Racing Legend Behind Anime Character Passes Away Aged 31

Tsurumaru Tsuyoshi, the celebrated racehorse who influenced a cherished character in the Japanese anime series Umamusume: Pretty Derby, has died aged 31. The iconic thoroughbred died on 2 August at Yoshino Farm in Japan, where he had enjoyed his retirement. According to his long-standing support group, Tsurumaru Tsuyoshi was located unable to get up from his pasture and could not be rescued despite medical treatment. The horse’s death prompted official tributes from the Umamusume franchise, which has constructed its premise around converting real racehorses into animated characters whose personalities and designs mirror their actual racing careers. Tsurumaru Tsuyoshi’s character is performed by Yoshino Aoyama and depicted as an ambitious runner whose determination exceeds her physical capabilities—a reflection of the real horse’s gifted though frequently injured career.

A Champion Heritage in Dual Spheres

Born on 6 April 1995, Tsurumaru Tsuyoshi was the son of legendary racehorse Symboli Rudolf and enjoyed a distinguished career on the Japan racing scene. During his racing career, he won five of his eleven races, including the prestigious 1999 Asahi Challenge Cup and the Kyoto Daishoten—triumphs that established his status as a formidable competitor. However, his racing trajectory was fundamentally changed when he suffered a severe left-front leg fracture during the 2000 Arima Kinen, an incident that would shape the remainder of his life and directly inspire his anime character’s portrayal of determination despite physical limitations.

The Kyoto Daishoten triumph proved notably important, as it pitted Tsurumaru Tsuyoshi in competition with multiple horses who would themselves develop into significant characters in the Umamusume franchise, such as Special Week, Mejiro Bright, T.M. Opera O, and Stay Gold. This convergence of real racing history and fictional adaptation illustrates how Umamusume seamlessly weaves authentic sporting narratives into its animated universe. Tsurumaru Tsuyoshi’s shift from racing to retirement at Yoshino Farm allowed him to spend his final decades in tranquil surroundings, where he continued to be engaged and satisfied until his last moments, exemplifying the consideration and regard shown to Japan’s retired racing legends.
