The economic platform of Prime Minister Sanae Takaichi, quickly dubbed ‘Sanaenomics’, is not a radical break but a clear continuation and evolution of the policies pioneered by her mentor, Shinzō Abe. Where Abenomics was primarily an aggressive strategy to combat decades of deflation, Sanaenomics is positioned as an expansionary, pro-growth agenda tailored to a new era of cost-push inflation and heightened geopolitical insecurity.
The Continuity of the ‘Three Arrows’
Takaichi’s plan maintains the conceptual structure of Abenomics, often framed around ‘three arrows’, but with a significant shift in emphasis:
- Monetary Easing: Like her predecessor, Takaichi favours continued loose monetary policy by the Bank of Japan (BOJ). She believes the current inflation, driven largely by import costs and a weak yen, is “cost-push” rather than the “demand-pull” inflation necessary for confirming Japan has permanently escaped its deflationary trap. Her cautious stance is seen as pushing back against an immediate, aggressive interest rate hike by the BOJ, although she has stated the central bank retains autonomy in choosing policy tools.
- Expansionary Fiscal Policy: This is the most pronounced aspect of Sanaenomics, mirroring the first arrow of Abenomics but with an even greater push for government spending. Takaichi advocates for a “responsible proactive fiscal policy” and has indicated a willingness to issue deficit bonds to fund crucial measures.
- Structural Reform and Investment: While Abe struggled with the “third arrow,” Takaichi is reframing it entirely. Her focus is less on deregulation and more on state-backed “crisis management investment” in strategic areas vital for national and economic security.
The New Economic Core: Security-First Spending
The defining feature of Sanaenomics is the merging of economic policy with national security. This goes beyond mere defence budgets and aims for self-sufficiency and technological sovereignty in an increasingly volatile world.
This heavy reliance on state-directed spending, especially in technology and defence, caused the Nikkei 225 to surge and the Yen to weaken immediately following her election, as markets factored in higher inflation expectations and prolonged monetary easing.
Fiscal Policy: Populist Relief vs. Fiscal Discipline
Takaichi’s economic plan is designed to directly address the cost-of-living crisis—the key domestic issue that has undermined the LDP’s support. She plans to put money back into households’ hands through:
- Refundable Tax Credits: A mechanism that acts as a form of “negative income tax,” providing cash payments to low-income households that don’t earn enough to benefit from standard tax cuts.
- Tax Relief: Abolishing the provisional gasoline tax rate and increasing the basic income tax deduction.
- Wage Policy: She prefers a ‘high-pressure economy’ (maintaining tight macro supply-demand conditions) to naturally push up wages, rather than the more direct government-mandated minimum wage increases favoured by her predecessors. Her philosophy is focused on rewarding the working middle class.
However, this push for expansive fiscal policy runs a high risk of stoking inflation and further ballooning Japan’s already immense national debt, creating tension with the Ministry of Finance’s (MoF) drive for fiscal discipline.
Relationship with the Bank of Japan (BOJ)
Perhaps the most controversial aspect of Sanaenomics is Takaichi’s assertive stance toward the central bank. She has explicitly stated that the government bears responsibility for both fiscal and monetary policy, sparking concern over the BOJ’s independence.
While she acknowledges the BOJ’s autonomy in selecting tools, her assertion that the direction of policy should be coordinated with the government is seen by critics as a direct attempt to lean on the central bank to delay any further rate hikes. This is crucial as the BOJ is currently navigating the tricky path of normalising rates after years of ultra-loose policy—a path Takaichi’s expansionary fiscal impulse makes significantly more challenging. In effect, Takaichi is demanding BOJ compliance to keep the nominal interest rate below the nominal growth rate, a key condition for managing Japan’s debt pile.
An Unflinching Trajectory: Assessing the Likely Transformation of Japan under Takaichi
Sanae Takaichi’s premiership, if she can navigate the immediate challenge of forging a working parliamentary coalition, is unlikely to usher in a new era of reformist politics. Instead, it is poised to accelerate a major ideological shift already underway, moving Japan towards a more nationalist, security-driven state that is prepared to take bolder, more divisive steps on the global stage. Her tenure will be a test of whether hardline conservatism can address the deep-seated economic and demographic vulnerabilities of modern Japan.
Foreign Policy: The Rise of an Assertive Japan
Takaichi’s impact will be most keenly felt in foreign and security policy, where she promises a departure from the measured pragmatism of recent predecessors:
- Constitutional Revision (Article 9): Takaichi will use the full weight of the Prime Minister’s office to push for the formal revision of the pacifist Article 9 of the Constitution. While Shinzō Abe laid the groundwork, Takaichi’s unwavering commitment to the issue makes it a central pillar of her mandate. If successful, this would be a watershed moment, fundamentally redefining Japan’s self-defence capabilities and its role in global security.
- Security-First Diplomacy: The commitment to increase defence spending to 2 percent of GDP or more is non-negotiable. This will translate into large-scale investment in counter-strike capabilities and advanced military hardware, significantly enhancing Japan’s deterrent posture.
- Regional Tensions: As a renowned China hawk and a strong supporter of Taiwan, Takaichi’s diplomacy is likely to be assertive and confrontational. Her historical revisionism, particularly her stance on the Yasukuni Shrine, risks undoing the recent, fragile thawing of relations with South Korea and will undoubtedly draw ire from Beijing, leading to a potential spike in regional tensions and military ‘testing the waters’ by adversaries.
- US Alliance as a Cornerstone: Despite the potential volatility of the Trump administration, Takaichi’s focus on burden-sharing and her own hardline stance make her an ideologically compatible partner for Washington. She will strengthen the US-Japan alliance and push for deeper multilateral cooperation through blocs like the Quad.
Domestic Economy: The Sovereignty-Growth Trade-Off
On the domestic front, the transformation under ‘Sanaenomics’ will be an experiment in boosting growth through targeted state intervention, with two key long-term implications:
- Securitised Economy: As former Minister for Economic Security, Takaichi will permanently embed security concerns into economic policy. Expect massive state-backed investments in strategic technologies (semiconductors, AI, nuclear power) aimed at achieving national self-sufficiency and protecting supply chains. This represents a partial retreat from free-market globalisation towards a more state-capitalist, national-interest model.
- Fiscal Risk and Inflation: Her expansionary fiscal policy, coupled with her pressure on the Bank of Japan to delay rate hikes, poses a significant risk to Japan’s already precarious financial situation. While it may provide short-term relief to households and a boost to the stock market, the long-term danger is that it locks Japan into a permanent cycle of debt-fuelled spending and a persistently weak yen, exacerbating imported inflation and undermining the fragile push for fiscal discipline by the Ministry of Finance.
Society and Culture: A Paradox of Modernity
Takaichi’s election as the first female Prime Minister is a historic symbol, yet her conservative social agenda suggests she will not be a torchbearer for broad liberal social transformation:
- Limited Gender Reform: While she has pledged to appoint more women to her cabinet, her opposition to gender equality reforms such as legalising separate surnames for married couples and female imperial succession means that the underlying patriarchal norms of Japanese society and the LDP will remain largely unchallenged. Her premiership embodies the paradox of descriptive representation without substantive reform.
- Immigration Hardening: A crucial area where Takaichi promises a definite shift is immigration. Capitalising on populist sentiment, she has called for tighter restrictions and stricter enforcement against overstayers and illegal migrants. This stance risks further complicating Japan’s chronic labour shortage, a demographic time-bomb that requires increasing, not restricting, foreign workers. Instead of facilitating long-term integration, her policies may intensify the divide between an aging Japanese core and the foreign workforce it desperately needs.
In essence, Sanae Takaichi’s likely transformation of Japan is one of hardening resolve—nationally, economically, and ideologically. She is poised to be a pivotal figure who consolidates the nationalist, conservative legacy of Shinzō Abe, seeking to forge a more assertive and resilient Japan, even if it means sacrificing internal consensus and international stability with key neighbours in the process. The question for Japan is whether her Iron Lady conviction can overcome the structural headwinds and political instability of a fractured Diet.
