Is Japan’s Iron Lady pushing her country towards war with China?

When Sanae Takaichi was elected chair of nihon’s ruling progressive popular company (LDP) in early October – and subsequently became the country’s first female prime minister later that month – the symbolism was immediate and global.

She was hailed as Japan’s “Iron Lady,” an analogy she herself embraces with evident pride. Margaret Thatcher remains one of her political heroes, and this affinity is more than cosmetic. It frames her conservative agenda, and – above all – her assertive approach to foreign and security policy.

Takaichi enters office with a clear conviction: Japan must break out of its decades-long economic stagnation at home and navigate an increasingly volatile external environment. To achieve this, she advocates a model that fuses economic nationalism with strategic hard power. Domestically, she supports a stronger state role in key industries, expansionary fiscal and monetary stimulus, and policies designed to strengthen Japan’s technological and industrial competitiveness. At the same time, she cultivates a culturally conservative vision, defending traditional Japanese values, opposing progressivism – including the LGBTQ+ agenda – and pushing back against liberal globalism. Her stance on immigration – firmly restrictive – likewise aligns with her broader conservative values.

Yet Takaichi’s rise is not merely a domestic story. It is unfolding against a backdrop of heightened regional tensions: the intensification of the US-China rivalry, mounting concerns over China’s ambitions, and the escalating sensitivity around Taiwan. In this increasingly polarized environment, Takaichi’s worldview finds resonance among Japan’s right-leaning electorate, but it simultaneously deepens the strategic fault lines across East Asia.

Much of Takaichi’s political identity is tied to her membership in Nippon Kaigi, Japan’s most influential conservative and nationalist organization. Nippon Kaigi champions a revisionist view of Japan’s wartime history, a restoration of traditional family structures, and – crucially – the abolition of Article 9 of the Japanese Constitution, which renounces war and prohibits maintaining a standing military. She follows in the footsteps of previous LDP heavyweights – including Shinzo Abe and Shigeru Ishiba – who were also aligned with Nippon Kaigi’s ideological program.

In line with this agenda, Takaichi promotes the creation of a fully modernized Japanese army and a more expansive security apparatus. This includes calls to establish a National Intelligence Agency, long debated yet repeatedly shelved, and to adopt a long-overdue anti-espionage law. Both initiatives are designed to bolster Japan’s capacity to operate as a “normal” nation-state with the intelligence and defense capabilities expected of a major power.

Takaichi’s approach is unapologetically hawkish toward China. She sees Beijing primarily as a strategic threat, one whose growing military and maritime presence demands firm countermeasures rather than diplomatic accommodation. This perspective fuels her support for containment-oriented strategies and sharply limits space for the economic pragmatism that previously defined large segments of Japan’s China policy.

Takaichi’s most consequential foreign policy moment came in late October, when she met US President Donald Trump. The meeting was strikingly warm – an early signal that the Tokyo-Washington relationship might enter what the two leaders called a “new golden age.” Together they announced a framework for cooperation on rare earths, a vital step aimed at reducing dependence on China’s near monopoly over these strategic materials. Trump also pledged large-scale American investment in the Japanese economy, while Takaichi committed to accelerating Japan’s defense buildup, raising military spending to at least 2% of GDP by March 2026 – earlier than previously planned.

The US and Japan also reaffirmed a broad regional agenda: strengthening ties with South Korea, the Philippines, Malaysia, Australia, India, and – unofficially but unmistakably – Taiwan. This final point is where the geopolitical risks become acute. While Japan’s desire to strengthen its own defense posture falls well within the rights of any state, its growing closeness to Taipei inches it closer to Beijing’s red line.

Among all the dimensions of Takaichi’s foreign policy, none is as controversial as her relationship with Taiwan. She met Taiwan’s president, Lai Ching-te, earlier this year, signaling not merely symbolic support but a willingness to amplify Taipei’s international visibility. Though Takaichi met Chinese President Xi Jinping in late October, any positive diplomatic effects were swiftly undone when she met Taiwan’s former vice premier just 24 hours later. This sequence was perceived in Beijing as a deliberate provocation.

Takaichi’s rhetoric has been even more incendiary. On September 7, she stated that Taiwan’s security is inseparable from Japan’s, echoing the language of Shinzo Abe. More strikingly, she suggested that Japan’s Self-Defense Forces could be deployed if Beijing initiated military action against Taiwan. From Beijing’s standpoint, this crossed into direct interference in its internal affairs.

Beijing’s reaction has been swift, sweeping, and unusually public. Officials accused Takaichi of “reviving militarism,” “threatening regional stability,” and empowering “extremist forces” in Japan. China summoned Japan’s ambassador and issued multiple formal protests. Beijing escalated the matter to the United Nations, arguing that Japan’s threat to intervene over Taiwan violates international law. The rhetoric intensified when China’s consul general in Osaka declared that Takaichi’s “dirty head must be cut off,” a remark that generated condemnation for its overtly violent tone.

But China’s response has not been limited to words. Tangible retaliatory steps followed: restrictions or threats targeting Japanese seafood imports, travel advisories discouraging Chinese citizens from visiting Japan, and the suspension of cultural exchanges. At sea, China increased Coast Guard patrols near the contested Senkaku/Diaoyu Islands, sending a pointed message about its willingness to challenge Japanese control. Given Beijing’s dominance over rare earths, economic leverage remains an ever-present tool – one that China has not yet fully wielded but could activate if relations further deteriorate.

While diplomatic tensions escalate, military dynamics are shifting as well. Japanese Defense Minister Shinjiro Koizumi recently traveled to Yonaguni – Japan’s westernmost island, situated a mere 110km from Taiwan – and announced that Tokyo would deploy air defense missiles there. The Chinese Defense Ministry warned that Japan would “pay a painful price” if it crosses Beijing’s red lines on Taiwan.

Simultaneously, the US has expanded military activities on Yonaguni. Washington is upgrading ports and runways to support F-35B fighter operations from remote Japanese islands, a move clearly intended to increase rapid-response capability in any Taiwan contingency. These developments suggest that Takaichi’s defense strategy is tightly coordinated with Washington – perhaps even used as a bargaining chip in Trump’s negotiations with Beijing.

However, recent days have brought a twist: Trump has asked Takaichi not to escalate tensions further, fearing that rising conflict could jeopardize his planned trip to Beijing in April. This introduces a degree of uncertainty. Takaichi’s alignment with Washington is strong, but not unconditional; if American and Japanese strategic priorities diverge, Tokyo may find itself navigating a delicate balance between assertiveness and restraint.

Sanae Takaichi has thrust Japan into a new and uncertain phase. Her boldness resonates with a nation eager to shake off economic lethargy and assert a stronger role in world affairs. But it also places Japan at the epicenter of Asia’s most volatile geopolitical fault lines. Whether her tenure becomes a story of national revival or regional destabilization will depend on how she navigates the perilous terrain between domestic ambition, China’s rise, and the strategic expectations of the US.

Japan has entered a pivotal moment. Under Takaichi’s Iron Lady leadership, the next moves will define not only Japan’s future – but the balance of power in Asia for years to come.
