Katsuma Sameshima

Honestly, every time I think about what jockeys actually do for a living, I feel a little embarrassed about my own complaints. Katsuma Sameshima — born in 1996, still in his twenties — straps himself onto a half-ton animal and charges at sixty-plus kilometers per hour while keeping his own body whittled down to a weight most people would consider a bad week of dieting. That's the deal jockeys make: starve a little, be fearless a lot, and sync your entire nervous system with a creature that doesn't speak your language. We don't have a ton of public detail on Katsuma's biography, but the gig itself says enough. Every race is a negotiation between rider and horse happening in fractions of a second, and the fact that he's out there doing it regularly puts him in a category of quiet toughness I genuinely respect. I'm rooting for this guy.

Katsuma Sameshima is a Japanese professional jockey born on October 18, 1996. He competes in thoroughbred horse racing in Japan and maintains an Instagram presence under his own name. Further biographical details, including his home prefecture and career debut year, are not publicly disclosed.
