Happy Birthday, Naoyuki Kotani! You're the only fighter we know who can go 15 matches without a loss and still manage to squeeze in two draws—talk about keeping things interesting! Your impressive run through Pride Fighting Championships and UFC has shown us all that lightweight doesn't mean light-hearted when it comes to determination.

From your relentless grappling skills to your fearless spirit inside the cage, you've given fans countless memorable moments. May this birthday bring you as much joy as you've brought excitement into the octagon—and may every round of cake be an undisputed victory today!
