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, career-long focus on legal affairs, and then suddenly he's Justice Minister under Kishida and he's the one signing off on executions, which in Japan is a genuinely heavy and largely thankless job 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.

Ryūji Koizumi is a Japanese politician born on September 17, 1952, in Saitama Prefecture. He is a graduate of the University of Tokyo. He has maintained an active presence with an official website and Instagram account.
