My Take

Katsumi Minai is the kind of career that rewards patience — the man didn't taste his first Grade 1 win until he was 35, riding Tamamocross in 1988, and yet he just kept going. As a JRA jockey from 1971 to 1999 he racked up over 1,500 wins across more than 13,000 rides, which tells you everything about consistency over flash. He got to sit on Oguri Cap and Narita Brian, two of the most mythologized horses in Japanese racing history, and in 1994 he had an almost absurdly good season — five Grade 1 wins, the JRA Special Prize, the Japanese Pro Sports Award, the whole sweep. Then he switched to training in 2000, promptly won the inaugural Japan Cup Dirt with Wing Arrow, and quietly kept stacking wins until retiring in 2023. Fifty-plus years in professional racing without ever needing to be the loudest name in the room. There's something genuinely cool about that.
