As science and technology (S&T) becomes central to economic growth, national security and geopolitical competition, governments face a shared challenge - turning world-class research and industrial capability into coherent national advantage. The question is no longer whether S&T policy matters, but how it is coordinated.

Internationally, one lesson is clear: for any country aspiring to be an S&T superpower, a centrally coordinating S&T policy is a structural necessity, not an administrative choice. As the National Technology Adviser to the UK Government, I bring an industry perspective to the UK's S&T policy headquarter (HQ).

Why a Centrally Coordinating S&T Function Matters

S&T shapes almost every major policy domain, from a country's industrial competitiveness and economic security, to defence, climate, health and digital governance. Yet governments are often organised vertically, with responsibilities structured within ministries focused on a specific policy domain.

Without strong coordination, even well-designed policies can fragment as technology rapidly changes what is possible. This means priorities become unclear, public money is spent less effectively, and governments may miss risks or opportunities that directly affect people's everyday lives. Leading S&T nations rely on a central function to set priorities, connect research, industry, regulation and security, and give ministers timely, evidence-based choices. This ‘guiding mind' is not one person's vision; it is where the wisdom of the country's strategic leaders meets political demands and aligns them.

S&T policy HQs now operate under growing international pressure. Emerging technologies blur civilian, commercial and security uses. Centrally coordinating functions therefore go beyond domestic alignment. They must horizon scan and respond quickly to external dynamics, balancing openness with resilience and partnering with likeminded countries while protecting critical capabilities. This is not about centralising control. It ensures S&T are treated as strategic national assets.

Japan's Evolving Institutional Foundation

Through the Cabinet Office and the Council for Science, Technology and Innovation (CSTI), Japan has established important foundations for a government-wide S&T policy coordination function. This supports cross ministerial alignment, helps translate high level political commitment into national strategy, and enables mission-oriented programmes and multiyear funding aligned to national priorities.

This institutional setup provides an important basis for long term direction, consistency across policy cycles, and faster alignment as global technological competition intensifies. For companies on the ground, this means making it easier to invest, innovate, and plan for the long term.

As emerging technologies increasingly cut across traditional ministerial boundaries, many countries — including Japan, the UK, and others — continue to consider how science and technology policy structures can evolve further to support faster integration of research, industrial strategy, security, and societal implementation.

How the UK Exercises the S&T "HQ Function" in Practice

The UK experience suggests the S&T policy HQ is best understood as a function rather than a single organisation. In the UK, it is exercised mainly through the Department for Science, Innovation and Technology (DSIT), linked to Cabinet level decision making and supported by cross government roles such as my role as the National Technology Adviser and the Chief Scientiofic Adviser network.

Effectiveness depends less on formal hierarchy than on active coordination, with the UK integrating science policy with industrial strategy, national security and foreign policy and disciplined priority setting under uncertainty.

Its role does not replace specific policy domain focused ministries, it is to integrate and spot connections. In other words, translating technical insight into policy relevant advice, connecting government, industry and academia, and supporting coherent choices in areas such as AI, quantum and advanced semiconductors.

Japan as a Strategic S&T Partner

For the UK, this coordinating function has enabled deeper, more structured partnerships with key allies, including Japan. A clear example is the UK—Japan Digital Partnership, led by DSIT on the UK side and by the Ministry of Internal Affairs and Communications, Ministry of Economy, Trade and Industry and the Digital Agency on the Japanese side. Through ministerial councils and senior official steering, it supports cooperation across the 4 pillars of the Digital Partnership; digital infrastructure and technologies, data, digital regulation and standards and digital transformation. This means faster, more resilient digital connectivity that underpins work, public services and daily life.

As international S&T cooperation deepens, S&T policy HQs functions are increasingly expected not only to enable collaboration, but also to manage risks such as research security in a proportionate and effective way.

The UK has strengthened internal coordination on research security to ensure that protective measures are applied in a proportionate, transparent and internationally aligned manner. Close cross government collaboration helps ensure that research security frameworks do not create unintended barriers to trusted cooperation, investment, or talent mobility with key partners such as Japan.

Looking ahead, there is strong potential to deepen collaboration on advanced and compound semiconductors, quantum technologies, AI governance, future digital infrastructure and resilient critical technology supply chains. The Horizon programme is a key opportunity to deepen our already great relationship and grow our economies and national resilience together.

Conclusion

Ultimately, being an S&T superpower is not defined only by scientific excellence or industrial scale. It is defined by the ability to mobilise S&T strategically through effective policy HQ functions nationally and internationally.

Countries that succeed will align domestic coordination with global partnership, translating capability into long term economic and strategic advantage. Japan's ambition is clear; internal and international collaboration will be central to delivering it.
