Seiji Kihara

Seiji Kihara is the kind of figure who rarely trends but often matters. Musashi, then the University of Tokyo, then the civil service, then elected office — on paper it reads like a checklist for the Japanese establishment. What interests me is where he ended up: Parliamentary Vice-Minister and later State Minister for Foreign Affairs, then Deputy Chief Cabinet Secretary. That last post is not a stage, it is a switchboard. You put someone there because you trust them to keep the machinery running while other people give the speeches. Foreign readers following Japanese politics tend to learn the prime ministers and stop there. I'd argue the more useful habit is learning the names in the second row — the coordinators, the ones who keep reappearing across different cabinets. Kihara, born in Tokyo in 1970 and still sitting in the House of Representatives, is squarely one of those names.
