SARGA.CO – Uma Musume: Pretty Derby fans around the world have been amazed by the uncanny ability of a former jockey turned YouTuber. At 79 years old, the man known by his stage name Matchan has stunned viewers with his talent for accurately identifying the real-life racehorses that inspired the characters in the popular game.
With over 40 years of experience in horse racing, Matchan rose to internet fame after appearing as a guest on an Uma Musume video. His appearance came right as the game was making its global debut, riding a wave of international popularity.
In the video, Matchan was shown clips of various Uma Musume horse girls and asked to guess which racehorse each character was based on.
Relying on visual cues like hair color, jockey uniforms, and behavioral traits, Matchan’s deep knowledge of horse racing history and pedigree impressed fans around the world.
According to gamerbraves.com, one standout moment was when Matchan correctly identified Special Week and even recalled the tragic circumstances surrounding the mare’s death during childbirth.
In another clip, he vividly remembered the incident involving Rice Shower, who suffered a fatal leg injury during the 1995 Takarazuka Kinen race.
His memory and attention to detail have left fans in awe. Some even say Matchan knows more about the horses—their names, personalities, and life stories—than the jockeys who once rode them.
Matchan’s guessing game videos first gained attention in 2021, when Uma Musume had just launched in Japan. He began uploading YouTube content where he demonstrated his skills in recognizing dozens of characters based on real-life horses.
Now, his videos have amassed over 4 million views, and his audience has grown even further thanks to the addition of English subtitles since the global release of the game last month.
Matchan has earned the affectionate nickname “Legendary Horse Racing Grandpa” from Uma Musume fans worldwide.
He’s also found a home in the broader community. Once just an anime viewer, Matchan now plays the Uma Musume mobile game and continues to make videos showcasing his impressive knowledge and passion.
Though Uma Musume draws its characters from real-world racehorses, its emotional core is rooted in the stories behind those horses—and that’s what makes Matchan so beloved.
His genuine admiration for the horses, paired with his heartfelt reactions, deepens the emotional resonance and historical appreciation behind the franchise.
Market value expected to reach US$1.73 billion by 2035
