My Take
Koji Onuma is the kind of guy who quietly earns your respect. Born in the summer of '79 in Higashiosaka — that gritty, industrial corner of Osaka famous more for small factories than for celebrities — he grew up in a place where you work with your hands and prove yourself through effort, not flash. Standing 178 cm, he's no giant by baseball standards, but Higashiosaka has a funny way of producing people who are tougher than they look. A Cancer born in the Year of the Sheep, which sounds gentle on paper, but anyone who knows the type knows there's a stubbornness in there that sneaks up on you. The details of his career are sparse in the public record, and honestly that kind of low-profile grind is its own statement — not everyone in baseball gets a highlight reel, but somebody still has to show up, do the work, and hold the lineup together. I respect that quietly.
