Tomoya Tsuboi

Tomoya Tsuboi, born in 1996 in Hamamatsu, Shizuoka, won gold at the 2021 world amateur championships before turning professional. That line deserves more attention than it gets. World gold in boxing is not something Japanese fighters collect casually, and it puts him in a very small group. What I find telling is what followed: bronze at both the 2022 Asian Games and the Asian championships. A world champion taking bronze at a regional event is not a decline, it is a reminder of how thin the margins are in this sport. One matchup, one judge's card, and the ranking rearranges itself. He came up through Nihon University and the Self-Defense Forces' physical training school, then carried that amateur pedigree into the paid ranks and won the WBO Asia Pacific bantamweight title in 2025. He is not the loudest name on a card, and he does not seem interested in being one. But read the results in order and the picture is clear enough. Fighters like this deserve a wider audience than they usually get.
