Sanae Takaichi: Japan's first female prime minister

On 21 October, Japan achieved a historic milestone as Sanae Takaichi, President of the Liberal Democratic Party (LDP), was elected as the 104th Prime Minister of Japan—the nation's first woman to hold the office. This watershed moment arrives at a critical juncture, as Japan navigates complex geopolitical currents and seeks to reassert its position as a cornerstone of stability and prosperity in the Indo-Pacific region.

Takaichi's ascension to the premiership represents not merely a symbolic breakthrough in gender representation but the culmination of a distinguished career marked by intellectual rigour, unwavering dedication to conservative principles, and a profound commitment to Japanese national interests.

The making of a stateswoman

Born in 1961 in Nara Prefecture, Sanae Takaichi's formative years were marked by academic excellence and early engagement with international affairs. After graduating from Kobe University's Faculty of Business Administration in 1984, she worked as a Congressional fellow in the United States, gaining invaluable insights into Western democratic institutions that would prove instrumental in shaping her worldview.

In 1993, Takaichi made her foray into the Parliament after getting elected into the House of Representatives as an independent candidate from Nara, championing political reform. Throughout her three-decade career in Parliament, she has held numerous ministerial portfolios, serving twice as Minister for Internal Affairs and Communications (2014–2017 and 2019–2020), and more recently as Minister of State for Economic Security. These positions have given her comprehensive experience in telecommunications policy, administrative reform, and the increasingly critical domain of economic security.

Coalition government

Following the LDP's loss of its parliamentary majority in recent elections, Takaichi's government was formed through a coalition with Nippon Ishin no Kai (the Japan Innovation Party), a centre-right reformist party. Whilst this places the government in a minority position within the Diet, the coalition agreement provides a foundation for reasonably stable governance. Nippon Ishin brings commitment to administrative reform, fiscal discipline, and constitutional revision—priorities that align substantially with Takaichi's conservative agenda. The successful negotiation demonstrates her capacity for political manoeuvre and willingness to build consensus when circumstances demand.

Upon securing victory in the LDP leadership contest, Takaichi articulated her governing philosophy with characteristic clarity: "Work, work, work." This declaration encapsulates her approach to leadership—grounded in tireless dedication, meticulous attention to detail, and unwavering commitment to advancing Japan's national interests. Her pledge to dedicate herself fully to these responsibilities offers reassurance that Japan's government will be characterised by seriousness of purpose and diligence in execution.

Continuing Abe's legacy

Takaichi is widely recognised as the legitimate inheritor of the political legacy of the late Shinzo Abe, Japan's longest-serving Prime Minister. Mr Abe's centre-right conservatism—characterised by commitment to security alliance with the United States, economic revitalisation through expansionary fiscal and monetary policies, and dignified assertion of Japanese national identity—has profoundly shaped contemporary Japanese political discourse.

As Mr Abe's protégé, Takaichi has consistently championed these principles, earning the moniker of Japan's "Iron Lady." Like Margaret Thatcher, she combines firm convictions with political pragmatism. Her commitment to "Abenomics"—the economic policy framework combining aggressive monetary easing, flexible fiscal policy, and structural reforms—signals continuity in Japan's approach to reviving economic growth and escaping deflationary psychology.

Perhaps no relationship will be more consequential for Takaichi's premiership than that with President Donald Trump

The Trump factor

Perhaps no relationship will be more consequential for Takaichi's premiership than that with President Donald Trump. In late October, President Trump is scheduled to visit Japan—his first visit during his second term—providing Takaichi with an immediate opportunity to establish personal rapport and reinforce the bilateral alliance that serves as the cornerstone of Japanese security policy.

Takaichi's credentials for this critical diplomatic engagement are considerable. As a former Congressional fellow with a deep understanding of American political culture, she is well-positioned to forge a productive working relationship with the American administration. The Japan-US alliance remains the indispensable foundation of regional security architecture in the Indo-Pacific. Takaichi's task will be to balance Japan's security imperatives with American expectations regarding burden-sharing, defence spending, and economic cooperation.

Her discussions with President Trump will encompass not merely security matters, but also economic issues, including trade relations, technology cooperation, and investment flows. Japan's substantial contributions to American manufacturing, its role in global supply chains, and its technological capabilities in sectors such as semiconductors position it as an invaluable economic partner.

Regional diplomacy

Beyond the bilateral alliance with Washington, Takaichi faces the imperative of strengthening Japan's ties with fellow Indo-Pacific nations. The forthcoming APEC summit in South Korea provides an early platform for her to engage regional leaders and advance Japan's vision for a free, open, and prosperous Indo-Pacific.

As the world's third-largest economy, Japan possesses significant economic leverage through development assistance, infrastructure investment, and technology transfer. The Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP) exemplifies Japan's commitment to rules-based economic integration. The Quad partnership—bringing together Japan, the United States, India, and Australia—represents another crucial forum for cooperation focused on maritime security, supply chain resilience, and technology collaboration. Relations with ASEAN nations constitute yet another dimension of Japan's regional diplomacy, built upon decades of economic partnership and development cooperation.

Economic revival

Takaichi's success will ultimately be judged by her ability to address Japan's formidable domestic challenges. Economic revitalisation stands foremost amongst these priorities. Takaichi's economic vision, rooted in the Abenomics tradition, emphasises fiscal activism, strategic industrial policy, and structural reforms aimed at unleashing private sector dynamism. Her government is expected to pursue targeted fiscal measures to stimulate domestic demand, support strategic industries such as semiconductors and artificial intelligence, and address regional economic disparities.

Structural reforms are essential: increasing labour force participation, particularly amongst women and older workers; promoting corporate governance reforms; and liberalising regulated sectors. Social security reform represents perhaps the most daunting long-term challenge. Japan's rapidly ageing population places enormous strain on pension and healthcare systems, whilst the declining birth-rate threatens intergenerational sustainability. Takaichi's government must craft policies balancing fiscal sustainability with social solidarity.

Global role

The international order is undergoing a profound transformation. Great power competition has returned, multilateral institutions face challenges, and principles of territorial integrity and rules-based governance are contested. In this fluid environment, Japan—as a major economy, technological powerhouse, and democratic society—has both the capacity and responsibility to contribute to international stability.

Takaichi's government must balance several imperatives: maintaining the bilateral alliance with the United States whilst pursuing strategic autonomy; engaging regional neighbours whilst managing competition with China; and contributing to global governance on issues ranging from climate change to digital regulation. Japan's "free and open Indo-Pacific" concept provides a framework emphasising sovereignty, rule of law, freedom of navigation, and economic openness.

Historic opportunity

Sanae Takaichi assumes the premiership at a moment pregnant with both peril and promise. The challenges confronting Japan are formidable, yet Japan possesses considerable strengths: a highly educated populace, world-class technological capabilities, substantial financial resources, and a democratic political culture providing mechanisms for accountability and renewal.

Takaichi's leadership will be tested across multiple dimensions simultaneously. Her success is not guaranteed, but her qualifications are substantial. Three decades of parliamentary experience, multiple ministerial portfolios, and deep engagement with pressing policy challenges have prepared her for this moment. Her pledge to "work, work, work" on behalf of the Japanese people reflects a seriousness of purpose that inspires confidence.

As the first woman to serve as Japan's Prime Minister, Takaichi carries the weight of historical expectation. Yet it would be a disservice to view her tenure solely through this lens. She has earned her position through merit, dedication, and political skill—qualities that transcend gender.

The international community, particularly in the Arab world and throughout the global South, should watch Takaichi's premiership with keen interest. Japan's experience navigating tensions between tradition and modernity, its commitment to technological innovation whilst preserving cultural heritage, and its evolving role in international affairs offer lessons of potential relevance to nations across the globe. A stable, prosperous, and engaged Japan contributes to global stability and offers a model of how a non-Western nation can achieve prosperity while maintaining cultural distinctiveness.

Takaichi's government represents both continuity and change—continuity in its commitment to conservative principles and alliance with the United States, change in its composition and priorities. As she embarks upon her tenure, the hope must be that she possesses the wisdom to preserve what is valuable in Japan's political tradition, the courage to reform what is outdated, and the vision to position Japan for success in an uncertain century. The Japanese people, and indeed the broader international community, have every reason to wish her well in this momentous undertaking.
