Doctrine — stated goals and content

LDP-reformist supply-side plus Takenaka financial reform — Koizumi campaigned on "structural reform without sanctuaries" and "no recovery without reform," explicitly breaking with Obuchi-Mori fiscal activism. Economic school: Anglo-Saxon-influenced supply- side liberalisation plus aggressive NPL resolution, inside a still-Keynesian BoJ QE monetary frame. Centre-right LDP but reform-hawk against old LDP zoku politicians and Tanaka faction. Key policy content: (i) Takenaka Plan October 2002 — bank NPL disposal programme forcing Resona Bank nationalisation June 2003 and UFJ-Mitsubishi Tokyo merger 2005, NPL ratio fell from 8.4% (2002) to 2.9% (2005); (ii) BoJ Quantitative Easing under Fukui expanded reserve target from ¥5tn to ¥30-35tn by 2004, lifted March 2006; (iii) Postal Privatisation Law October 2005 splitting Japan Post into four successor companies (mail, savings, insurance, counter services) phased 2007-2017 — the signature reform, triggered August 2005 snap election after Upper House rejection; (iv) Iraq Special Measures Law July 2003 authorising SDF humanitarian dispatch to Samawah (non-combat role, 2004-2006); (v) road-related special-account and four expressway-corporation privatisation October 2005; (vi) trinity reform 2003-2006 — ¥4tn local-government tax transfer plus subsidy cuts; (vii) Yasukuni visits annually 2001-2006 strained China and Korea relations. Popularity: sustained ~45-70% approval, LDP landslide in September 2005 snap election (296/480 seats) on postal privatisation mandate; handed off to Abe September 2006. Coherence line: supply-side structural reform plus QE accommodation plus banking clean-up — the cleanest doctrinal pivot away from Obuchi-Mori fiscal activism.

Notes

Koizumi's postal privatisation is treated as the signature reform despite staggered 2007-2017 implementation; subsequent reversals under Hatoyama captured in a separate policy block when created.
