Ryūji Koizumi

Ryuji Koizumi is the kind of politician who makes you realize just how invisible the engine room of government actually is — not a household name, not a talk-show regular, just a quietly methodical Saitama lifer who put in the decades of LDP groundwork that most people never bother to notice. Tokyo University pedigree, a start at the Finance Ministry, nine terms in the lower house, and then Justice Minister under Kishida from 2023 to 2024 — a post that carries the heavy, largely thankless responsibility for approving executions that almost nobody talks about openly. No showboating, no Twitter drama — just the unsexy machinery of governance, done with a kind of steady persistence that honestly deserves more credit than it gets. The political world needs its workhorses, and Koizumi is one of them.
