# Japan's Military Expansion Set to Accelerate as Takaichi Leverages Electoral Mandate Against China

The Current Situation

Japan stands at a critical juncture in its post-World War II security posture. Prime Minister Sanae Takaichi, fresh from converting a fragile majority into a landslide victory in the February 8 snap election, now commands more than two-thirds of parliamentary seats—the strongest political mandate a Japanese leader has held in years. In her first post-election speech to parliament on February 20, Takaichi painted China as Japan's primary security threat and announced sweeping plans to overhaul the nation's defense strategy (Articles 1, 2). The relationship between Tokyo and Beijing has deteriorated to its lowest point in years, triggered by Takaichi's November comments suggesting Japan would activate its self-defense forces in the event of an attack on Taiwan that threatened Japanese territory. China's response has been comprehensive and calculated: recalling pandas from Tokyo's Ueno Zoo, throttling rare earth exports, curbing Chinese tourism, canceling flights and concerts—a multi-pronged pressure campaign designed to force Japan's capitulation (Article 5). Yet rather than backing down, Takaichi has doubled down. With defense spending already approaching 2% of GDP by the end of March, she has announced plans to revise Japan's three core security documents this year and accelerate reviews of military export rules (Articles 3, 4).

Key Trends and Signals

Several critical trends emerge from the current situation: **Political Momentum**: Takaichi faces "little political resistance" with her super-majority coalition (Article 1). This represents a dramatic shift from Japan's recent political instability and gives her unprecedented freedom to pursue controversial security reforms. **Systematic Military Normalization**: The proposed changes go beyond incremental adjustments. According to Article 1, Takaichi's Liberal Democratic Party is considering scrapping rules that limit military exports to non-lethal equipment—a fundamental departure from Japan's post-war pacifist stance. This follows her predecessor Ishiba's assessment of "the most severe and complex security environment" since World War II (Article 4). **China's Escalating Pressure Campaign**: Beijing's retaliatory measures are deliberately targeting Japan's soft power and economic vulnerabilities rather than triggering immediate crisis (Article 5). This suggests China is testing Takaichi's resolve while maintaining room for de-escalation. **The Trump Factor**: Article 3 identifies a crucial dynamic—Takaichi is "walking a fine line" to secure support from US President Donald Trump ahead of her Washington visit next month. She must demonstrate Japan will "shoulder greater responsibility in countering China" while maintaining rhetorical space for "mutually beneficial relations" with Beijing.

Predictions: What Happens Next

### 1. Military Export Ban Will Be Substantially Relaxed Within the next three months, Japan will announce significant changes to its self-imposed weapons export restrictions. The policy panel proposal mentioned in Article 1 to scrap limitations on lethal equipment exports will likely be implemented in modified form. Takaichi has framed this as necessary to "strengthen the deterrence and response capabilities of our allies and like-minded partners" while reinforcing Japan's defense industrial base (Article 4). Expect initial exports to focus on defensive systems and non-controversial platforms, potentially including sales to Southeast Asian nations facing Chinese maritime pressure. This will be presented as collective security rather than militarization. ### 2. New Defense Strategy Documents by Mid-2026 Takaichi explicitly committed to revising Japan's three major defense policy documents "this year" (Articles 1, 4). Given the political capital from her landslide victory and the urgent framing of the security environment, these documents will likely be released by summer 2026, possibly timed with or following her Washington summit. These revisions will codify expanded counter-strike capabilities, deeper integration with US forces, and potentially new interpretations of constitutional limitations on collective self-defense—particularly regarding Taiwan scenarios. ### 3. China-Japan Tensions Will Stabilize at Higher Baseline Despite the current pressure campaign, neither side wants uncontrolled escalation. Article 2 notes that Takaichi still speaks of "mutually beneficial relations" and building "constructive and stable" ties with China. Beijing's economic leverage has limits—Japan remains a significant economic partner and regional power. Expect tensions to plateau at this elevated level rather than spiral into crisis. China will maintain pressure through economic and diplomatic measures, but both sides will avoid military incidents that could trigger unwanted escalation or force Trump's intervention. ### 4. The Washington Summit Will Yield a Stronger Security Commitment Takaichi's March visit to Washington will produce a joint statement or agreement that significantly enhances US-Japan security cooperation. Article 3 identifies managing the relationship with Washington as Takaichi's priority. She will likely offer concrete commitments on defense spending increases, enhanced base hosting arrangements, or operational coordination—exactly the burden-sharing Trump demands from allies. This will further lock Japan into a confrontational posture toward China, making future de-escalation more difficult.

The Bigger Picture

Article 6's analysis of Japan's "troubling shift" away from its pacifist constitution may prove prescient. Takaichi has the political mandate, the external threat narrative, and the US pressure to fundamentally reshape Japan's security posture. The question is no longer whether Japan will pursue military normalization, but how far and how fast. China's pressure campaign appears designed to raise the costs of this trajectory, but may paradoxically strengthen domestic support for Takaichi's harder line. Having staked her political future on standing firm against Chinese "coercion," backing down now would be politically catastrophic for the prime minister. The next six months will likely see Japan cross several post-war red lines on military policy, setting the stage for a fundamentally different security architecture in Northeast Asia—one that increases the risk of miscalculation in any future Taiwan crisis.
