Takaichi assumed the premiership after a turbulent intra-LDP succession triggered by Prime Minister Ishiba's loss of working majority in the upper house following the July 2025 election. Her election as LDP president on October 4, 2025, and her subsequent investiture on October 21 with the support of Ishin no Kai after the LDP–Komeito coalition fractured, reset the political alignment of Japanese conservatism. Takaichi is a protégé of the late Shinzo Abe and a long-time advocate of expanded defense capabilities, constitutional revision, and assertive monetary–fiscal coordination.
On defense, the Takaichi government has accelerated implementation of the 2022 National Security Strategy's commitment to raise defense spending to 2 percent of GDP, with explicit political signaling toward a 3 percent trajectory by the early 2030s. The supplementary budget passed in December 2025 included accelerated procurement of Tomahawk Block V missiles from the United States, additional Type 12 missile production, hypersonic glide vehicle development funding, and the second tranche of GCAP (Global Combat Air Programme) UK–Italy–Japan financing.
The Taiwan question structures the strategic environment. Takaichi's December 2025 Diet testimony asserting that 'a Taiwan contingency could constitute a survival-threatening situation' under the 2015 collective self-defense legislation triggered the strongest Chinese diplomatic response in a decade, including export restrictions on processed rare earths and a temporary halt to Japanese seafood imports. The statement was politically significant because it moved Japanese declaratory policy beyond the studied ambiguity maintained by Abe, Suga, Kishida and Ishiba.
The operational implications are real. Japan Self-Defense Forces have accelerated the southwest island defense buildup, with new Ground Self-Defense Force missile units established on Ishigaki, Miyako and Yonaguni, and the deployment of additional Patriot PAC-3 batteries on Okinawa. The U.S.–Japan Alliance Coordination Mechanism has been activated more frequently in 2025 than in any prior year, and joint planning for non-combatant evacuation from Taiwan has been formalized.
On energy, Takaichi has reversed the cautious post-Fukushima nuclear posture more decisively than her predecessors. The seventh Strategic Energy Plan, finalized in November 2025, targets a 20 percent nuclear share of electricity generation by 2030 and explicitly endorses the construction of next-generation reactors at existing sites — a politically taboo position for most of the post-2011 period. Restart approvals have been accelerated for additional reactors at Kashiwazaki-Kariwa, Tomari, and Genkai, and the Nuclear Regulation Authority has been instructed to publish more predictable decision timelines.
LNG strategy has been recalibrated. JERA, the merged utility fuel-procurement entity, has signed additional 15-year offtake agreements with U.S. Gulf Coast producers and Qatar's North Field expansion, while maintaining strategic flexibility in Australian and Southeast Asian sources. The recalibration reflects two judgments: that the energy transition will be longer than the 2050 net-zero pathway implies, and that the Taiwan Strait scenario requires substantially deeper strategic petroleum and LNG reserves.
On monetary policy, the Bank of Japan's normalization path has continued under Governor Ueda, with the policy rate raised in incremental steps through 2025 to 0.75 percent. Takaichi has been historically critical of premature tightening but has signaled, through her appointed Finance Minister, that she will not seek to constrain BOJ independence. The yen has stabilized in a 145–155 per dollar range after the volatility of mid-2024, and JGB yields at the long end have risen toward 2 percent for the first time since 2012.
On industrial policy, the Takaichi government has expanded the semiconductor support framework initiated under Kishida. The Rapidus 2nm logic fab in Hokkaido has received a second tranche of public funding, and TSMC's third Kumamoto facility has been formally subsidized. The targeted semiconductor envelope through 2030 now exceeds ¥15 trillion in committed public support. Beyond semiconductors, Japan has expanded subsidies for battery, EV, and quantum technology production, and has tightened FDI screening under the revised Foreign Exchange and Foreign Trade Act.
The U.S.–Japan relationship is structurally robust but operationally turbulent. The Trump administration's April 2025 imposition of 24 percent reciprocal tariffs on Japanese imports, partially negotiated down in the July 2025 framework agreement to 15 percent across most categories with carve-outs for autos and semiconductors, created a meaningful but managed shock. The framework agreement included Japanese commitments to additional U.S. agricultural imports, accelerated defense spending, and a $550 billion investment commitment over five years, structured primarily through private-sector JBIC-anchored vehicles rather than direct fiscal transfers.
On China, Takaichi's posture is firmer than her predecessors' but pragmatic on commercial questions. Japanese FDI in China has continued its multi-year decline, falling another 18 percent in 2025, while Japanese capital expenditure in Southeast Asia, India and Mexico has accelerated. The Japan External Trade Organization's 2025 survey indicates that 38 percent of Japanese manufacturers in China are actively restructuring supply chains, up from 22 percent in 2022. The recent Chinese restrictions on rare earths and gallium exports have intensified Japanese investment in Australian and Canadian alternative sources.
Three implications for regional and global decision-makers follow. First, the probability of a Taiwan Strait crisis sufficient to trigger Japanese defense activation has risen meaningfully, although the modal scenario remains below the threshold of kinetic conflict. Corporate continuity planning for a Taiwan disruption should treat Japan as both at risk and a likely responder, not as a neutral safe haven. Second, Japan's nuclear restart and additional LNG procurement will tighten Asia–Pacific gas markets at the margin and reinforce U.S. Gulf Coast and Qatari export economics. Third, Japanese outbound investment in Southeast Asia, India and increasingly Mexico represents a structural reorganization that will sustain demand for execution-focused advisory across legal, operational, M&A and political risk dimensions.
