Picture one of Japan’s most legendary racehorses—a powerful champion beloved by millions. Now, imagine that same champion reborn as a high-energy anime girl with a love for singing and festivals (Kita Black Uma Musume).
This is the fascinating world of Umamusume: Pretty Derby. At its heart is Kitasan Black, a character whose story uniquely blends real sports history with digital superstardom, making her a true pop culture icon.
From Racetrack Legend to National Icon: Who Was the Real Kitasan Black?
Before she was an anime star, the real horse Kitasan Black was an absolute force on the Japanese racetrack. A powerful and stamina-rich champion, he dominated Japan’s most prestigious events. His incredible race history includes victories in the Tenno Sho, Japan Cup, and the Arima Kinen—a marquee event often compared to the Super Bowl of Japanese horse racing.
Adding to his celebrity status was his owner, the beloved and famous enka singer Saburo Kitajima. Whenever Kitasan Black won a major race, Kitajima would often delight the cheering crowds by singing his hit song “Matsuri” (Festival), turning the winner’s circle into a national celebration. This unique connection made the horse a true fan favorite far beyond the typical racing audience.
This real-world blend of athletic greatness and show business is exactly what inspired the Umamusume character. Her cheerful, idol-like personality and dream of putting on a fantastic “victory concert” are a direct, charming tribute to the legacy the real horse Kitasan Black built with his owner.
Kita Black Uma Musume: How Kitasan Black Became a “Must-Have” Item in the Game

While you can train a playable version of Kitasan Black, her biggest in-game impact came from something different: a “Support Card.” In Umamusume, you don’t just collect racers; you also collect these cards. Think of them as special coaches or mentors you assign to help train your other characters, providing crucial boosts and skills.
So, what made the Kitasan Black support card so special? Most “coaches” in the game specialize in one or two areas, like speed or stamina. Her card, however, was like a legendary, all-in-one mentor who excelled at almost everything. Using it provided a massive advantage across the board, making the difficult training process significantly easier and more consistent, no matter which horse girl you were raising.
This universal power made her card an instant “must-have.” For months after its release, nearly every high-level training guide recommended her, and players would save their in-game currency for a chance to get this one item. This legendary support card is a huge reason why, for many players, the name Kitasan Black became synonymous with guaranteed success.
Kitasan Black’s Dual Legacy: Where Sport Meets Digital Stardom
Kitasan Black embodies how Umamusume transforms a beloved racehorse’s legacy into a powerful new narrative. She is more than just a game character; she is a cultural bridge connecting the thrill of the racetrack to a new generation of fans.
Her story perfectly illustrates this unique magic, showing how the spirit of a real-world champion can be reborn in a digital world. The character’s journey is a direct, charming tribute to the legacy built by the horse and his owner, cementing her as an icon where a great legend can gallop across any medium.
