Ryūji Ōkubo

He made his way down to Kyoto Sangyo University, which means he traded Hokkaido's open skies for the dense, layered culture of ancient Kyoto, and that kind of geographic leap tends to shape a person in ways that don't show up on a resume. He came of age right as Japan's bubble economy was inflating and then spectacularly popping, and that generation carries a certain groundedness — they've seen both the excess and the hangover. He comes from a family steeped in racing — his father trained Narita Brian — and has quietly built a stable with eight Grade 1 wins; it suggests a guy comfortable enough in his own lane that he doesn't need the validation.
