Takaichi Landslide Paves Way for Rapid Japanese Defence Expansion

The regional security architecture of the Asia-Pacific has undergone a tectonic shift following the historic landslide victory of Prime Minister Sanae Takaichi in Japan’s snap election on 8 February 2026. Takaichi’s Liberal Democratic Party (LDP) secured 316 of the 465 seats in the House of Representatives, achieving a commanding two-thirds supermajority. When combined with its coalition partner, the Japan Innovation Party (JIP), the administration now controls 352 seats. This decisive mandate effectively removes the legislative gridlock that has historically hampered Japan’s military normalisation, granting Takaichi the political runway to accelerate the nation’s most significant defence build-up since the Second World War.

​Strategic Mandate for Rearmament

​For the international defence and aerospace sectors, this result signals a move from theoretical policy to rapid execution. Takaichi, often described as Japan’s 'Iron Lady', has already committed to bringing Japan’s defence spending to 2 per cent of GDP by the end of fiscal 2025—two years ahead of the previous schedule. The record-breaking FY2026 budget, estimated at ¥122 trillion (US$783 billion), prioritises 'counterstrike capabilities' and the domestic production of advanced missile systems. This fiscal aggression is designed to deter regional adversaries, particularly China and North Korea, while positioning Japan as a more autonomous security actor capable of projecting power across the First Island Chain.

​Reports from the Center for Strategic and International Studies (CSIS), the Hudson Institute, and the Foreign Policy Research Institute (FPRI) indicate that the election outcome serves as a public endorsement of a more 'muscular' foreign policy. Analysts suggest that the supermajority will facilitate the establishment of a new national intelligence secretariat and the passage of an anti-espionage law, both of which are critical precursors to deeper technology sharing with AUKUS and Five Eyes partners. The Takaichi administration is also expected to move swiftly to relax decades-old restrictions on arms exports, a move that could see Japanese aerospace and maritime hardware entering the global market more aggressively.

​Deepening the Trump-Takaichi Alliance

​The geopolitical angle is further sharpened by the close alignment between Takaichi and US President Donald Trump. Following the results, President Trump congratulated Takaichi on social media, praising her 'Peace Through Strength' agenda. This personal rapport is expected to translate into increased procurement of US-made platforms, including F-35 fighter jets and Tomahawk cruise missiles, while simultaneously increasing pressure on Tokyo to fund a larger share of the US military presence in Japan. The 'Trump-Takaichi' era is likely to be defined by transactional yet high-intensity security cooperation, focusing on shared military infrastructure such as airfields and logistics hubs across the Second Island Chain.

​Asia-Pacific Security and Industrial Policy

​The regional reaction has been mixed, with Beijing warning against the 'revival of militarism' and Taipei welcoming the stability of a pro-Taiwan government in Tokyo. Takaichi has been vocal about the potential for Japanese military intervention in a Taiwan Strait contingency, a stance that has already led to trade friction with China. Domestically, the 'Takaichi-nomics' approach links security with industrial policy, earmarking strategic investments for semiconductors, artificial intelligence, and shipbuilding. This holistic view of 'economic security' aims to ensure that Japan’s defence industrial base is not only technologically superior but also resilient against supply chain coercion.

​Reflecting on her victory, Prime Minister Takaichi stated in a televised interview as the results were confirmed: “This election involved major policy shifts—particularly a major shift in economic and fiscal policy, as well as strengthening security policy. If we have received the public’s support, then we truly must tackle these issues with all our strength.” Meanwhile, Robert Eldridge of the Global Risk Mitigation Foundation noted the inevitability of the shift, stating, “Because the quality and quantity of the weapons systems and militaries are growing, it is expected and understandable for Japan to increase its defence spending.”
