Japan Prime Minister Sanae Takaichi used her first post-election address to parliament to warn of growing pressure from China and to outline a sweeping overhaul of Japan’s defence posture and economic security policies. Strengthened by a landslide lower house victory that handed her coalition a two-thirds majority, Takaichi signalled an assertive strategic shift in response to what she described as the most severe security environment Japan has faced since World War II.
Her remarks come after diplomatic tensions with Beijing intensified following her earlier statement that Japan could deploy force if a conflict over Taiwan threatened Japanese territory.
Security Threat Perceptions
Takaichi highlighted China’s expanding military activities and what she described as attempts to change the status quo through coercion in the East China Sea and South China Sea. She also cited closer security coordination between China and Russia, as well as growing nuclear and missile threats from North Korea.
Framing the regional landscape as increasingly volatile, she argued that Japan must urgently adapt to a multi-layered threat environment combining conventional military risks, nuclear deterrence challenges, and economic security vulnerabilities.
Defence Strategy and Military Reform
The government will revise Japan’s three core security documents this year to produce an updated defence strategy. Takaichi also pledged to accelerate a review of military export rules to allow greater overseas sales and strengthen the domestic defence industrial base.
Japan has been expanding its military capabilities since 2023 and is on track to double defence spending to 2% of GDP by the end of the fiscal year, placing it among the world’s largest military spenders despite constitutional pacifist constraints.
She further announced plans to establish a national intelligence council chaired by the prime minister to coordinate intelligence gathering across agencies, including police and the defence ministry. Japan currently lacks centralized intelligence bodies comparable to the Central Intelligence Agency or MI5.
Economic Security and Supply Chains
Beyond defence policy, Takaichi proposed creating a Japanese equivalent of the U.S. foreign investment screening system to review overseas acquisitions in sensitive sectors. She also pledged to reassess rules governing foreign land purchases.
Reducing dependence on “specific countries” for critical materials is another priority. The government plans to work with allies to secure supply chains for strategic resources, including rare earth elements around Minamitori Island.
These measures reflect growing concern over supply chain vulnerabilities and economic coercion risks.
Energy Policy and Nuclear Restarts
Takaichi also promised to accelerate the restart of nuclear reactors idled after the Fukushima Daiichi Nuclear Power Plant disaster in 2011. Reviving nuclear energy is seen as vital for energy security, reducing fuel imports, and supporting industrial resilience.
Political Context and Strategic Direction
With a commanding parliamentary majority, Takaichi faces limited legislative resistance to her agenda. Her platform blends defence expansion, economic security measures, and industrial policy, reflecting a broader shift toward strategic autonomy and resilience.
Her closing remarks emphasised national resolve and proactive governance, arguing that a country unwilling to confront challenges cannot inspire confidence or hope.
Implications
Japan’s evolving security posture signals a major shift from postwar restraint toward proactive deterrence and regional strategic engagement. Expanded defence exports could strengthen the domestic arms industry and deepen security ties with partners.
Supply chain diversification and investment screening measures align Japan more closely with Western economic security strategies. However, these moves risk further straining relations with China, Japan’s largest trading partner.
Increased defence spending and intelligence coordination may enhance deterrence, but they also reflect a long-term structural transformation in Japan’s strategic identity.
Analysis
Takaichi’s agenda reflects a convergence of geopolitical anxiety and economic security priorities. Her framing of China as both a military and economic coercive force underscores Japan’s transition toward a comprehensive security doctrine that integrates defence, supply chains, technology, and energy policy.
The push to relax military export rules and expand defence production suggests Japan is positioning itself as a more active contributor to regional security networks. Meanwhile, efforts to secure rare earth supplies and screen foreign investment highlight the growing overlap between national security and economic policy.
The success of this strategy will depend on balancing deterrence with diplomatic stability. A stronger defence posture may enhance regional security cooperation, but it also risks escalating tensions if not paired with careful diplomacy.
In other words, Takaichi is steering Japan toward a more assertive security and economic strategy, reflecting a nation recalibrating its role amid intensifying regional rivalry and global supply chain competition.
