Japan's Foreign Policy Under Prime Minister Sanae Takaichi: A Multi-Perspective Analysis

• Prime Minister Sanae Takaichi is shifting beyond her initial "hawk" image to adopt a more pragmatic and multi-layered foreign policy.
• Her administration maintains the U.S. alliance as its central axis while actively broadening ties with Australia, South Korea, and ASEAN to increase Japan's strategic room for maneuver.

Regional Perspectives

• United States: The alliance remains central, but Japan has shown readiness to prioritize its own legal and diplomatic limits, such as on the Strait of Hormuz, rather than automatically following U.S. requests.
• Europe: Observers are questioning the future of Japan’s postwar pacifist identity due to increased military spending, potential constitutional revision, and debates over the "Three Non-Nuclear Principles."
• Australia: Both nations are deepening cooperation in critical minerals, energy, and defense, viewing each other as "quasi-allies" to mitigate over-reliance on Washington.
• South Korea: Despite ongoing historical disputes, the two governments have maintained functional cooperation on supply chains, energy, and security coordination under President Lee Jae-myung.
• China: Beijing remains critical of Takaichi’s stance on Taiwan, claiming her rhetoric undermines the foundational political documents of the bilateral relationship and that military buildup contradicts Japan's calls for regional stability.
• Southeast Asia: While Japan is trusted, there is significant reservation regarding whether its military expansion will marginalize ASEAN or force the region into confrontational bloc politics.

Strategic Implications

• Takaichi’s approach reflects a search for greater autonomy within the existing security framework rather than a clean break from U.S. leadership.
• The durability of this pragmatism remains a test, especially regarding unresolved historical issues and the balancing act between assertive deterrence and regional diplomatic stability.
