The 21st Century Japanese Prime Minister Through the 1970s and into the 1980s scholars of Japanese politics could reasonably characterizethepositionoftheJapanesePrimeMinisterinthe1955systemofLDPdominance asa‘missingleader’(e.g.Massey1976).TotheextentthatthecharacterizationoftheJapanese politicalsystemwasa‘pyramidwithoutapeak’(vanWolferen1989)wascriticized,itwas generallynotbecausescholarsfeltthattheprimeministerorcabinettrulyexercisedpowerat thetop.Traditionally,theJapaneseprimeminister’srolewastomanagefactionalbalancing andoverseeabottom-uppolicymakingprocess—totheextentthatprimeministerswereseen asleaders,theyweremostlyseenasengagingin‘reactiveleadership’(Hayao1993).
