Kengo Oishi

I'll be honest, the resume here stopped me mid-scroll: a guy from Nagasaki who trained as a psychiatrist, crossed the Pacific to study at UC Davis, and then pivoted into politics. That's not a path you stumble into by accident. I find something quietly compelling about someone whose old job was literally sitting across from people and actually listening to what's wrong, then deciding to do that for a whole region instead of one patient at a time. I'd bet he's the type who leans on data and reasoning rather than shouting the loudest in the room, the calm clinical brain in a field that usually rewards bluster. A Cancer, too, so I picture a stubborn streak under the mild exterior. I don't know him personally, but the trajectory alone earns my curiosity.
