[[Hideaki Tanaka]]'s paper "_[Political Leadership and Senior Civil Service Systems: An International Comparison of the UK, Netherlands, Germany, France, and Japan](https://www.jstage.jst.go.jp/article/issmeiji/63/2/63_208/_article/-char/ja)_" (Meiji University) asks a important question: as political executives gain more control, what protects the quality of policy advice inside government?
Tanaka's analytical framework is the idea of "contestability," which he defines as the extent to which policy ideas and advice can be openly tested and challenged - within the civil service, across government (including central units and advisory bodies), and from outside actors such as legislatures, think tanks, universities, and the media.
Through a five-country comparison (UK, Netherlands, Germany, France, and Japan), the paper argues that politicization is not automatically "bad" in every form, but that governance quality depends on whether institutional conditions still allow for credible counter-arguments, evidence, and review to meaningfully shape decisions.
On [[Public Sector Reform in Japan|Japan]], Tanaka's diagnosis is recent reforms strengthened prime ministerial control over senior officials while the bureaucracy successfully preserved its traditional career-based (in opposition to position-based) personnel practices, a combination that weakens contestability. He situates this shift against the backdrop of the postwar "1955 system" and its "iron triangle" style of policymaking (party factions, ministries and industry), then highlights how political-administrative reforms since the 1990s strengthened the prime minister's institutional position.
A key turning point is the 2014 reform package which created a [[Executive Personnel Systems|senior executive system]] centered on a candidate roster of about 600 people, from which appointments to specific posts are made - formally by ministers, but with required consultation with the prime minister and chief cabinet secretary, who can also press for particular appointments.
Tanaka's broader point is that when careers and top appointments become more centrally steerable while the system remains highly "closed" and seniority-based, bureaucratic autonomy declines and "free and frank advice" is eroded, a dynamic the paper links to "functional politicization" (機能的政治化), or anticipatory compliance. Japan's limited mid-career and external entry into senior roles makes it harder to bring in alternative expertise and perspectives, and the paper concludes that Japan ranks lowest in contestability among the five countries studied.
I found this paper genuinely impressive, though I should note I read it in Japanese with AI support, so I may well have missed nuances or misread parts of the argument. That said, the parallels with Germany are particularly interesting. Both countries have civil service systems classified as "closed," and in both cases senior appointments carry a degree of political involvement.
Yet Germany manages to sustain higher contestability, in Tanaka's assessment, because its public servants move far more across ministries, between government and the private sector, and accumulate diverse professional experiences throughout their careers... even when they remain formally within the civil service (and I am not really sure if I agree with him on this). Japan's system, by contrast (in his opinion!), keeps officials within their home ministry for most of their career, with limited cross-ministry rotation and minimal external hiring at senior levels. The result is that two systems that look similar on paper produce very different conditions for internal challenge and debate.
