The Largest Turning Point Since the War: The Comprehensive National Security Reform of the Takai Administration and a New Phase in the Japan-U.S. Alliance

On February 19, 2026, Prime Minister Sanae Takaichi declared in a policy speech at the House of Representatives that Japan is facing the "most severe security environment since the end of World War II." This speech marks a historic turning point in post-war Japan's security policy and announced a comprehensive national security reform agenda to counter the rising "coercion" from the Chinese Communist Party. The reforms span a wide range, including defense strategy, reorganization of intelligence agencies, arms exports, economic security, and strengthening supply chains.

Prime Minister Takaichi clearly identified three main threats driving this reform: China's military expansion, the deepening strategic cooperation between China and Russia, and the advancement of North Korea's nuclear and missile capabilities. In particular, she launched a direct criticism against China, stating that it is "intensifying attempts to unilaterally change the status quo through force and coercion in the East China Sea and South China Sea." Such frank diplomatic language is rare in Japan and highlights Tokyo's growing vigilance regarding China's activities around the Senkaku Islands and the broader Indo-Pacific region.

The increase in defense spending to 2% of GDP is a core element of the reform. For Japan, which has limited military spending to about 1% of GDP for decades, this move signifies a fundamental shift in strategic thinking. Achieving the 2% threshold will place Japan among the world's leading defense spenders. Prime Minister Takaichi promised to accelerate the military expansion plan initiated in 2023 and to raise defense spending to 2% of GDP by the end of March.

Organizational transformation is also underway. Prime Minister Takaichi announced that the Japan Air Self-Defense Force will be renamed the "Aerospace Self-Defense Force," along with the establishment of a new "Space Operations Group." This move reflects the increasing importance of satellite communications, surveillance systems, and space-based capabilities in modern warfare. The space domain is being positioned not merely as a supplementary role but as a central pillar of national defense.

Significant progress is also evident in the operational aspects of the Japan-U.S. alliance. On February 20, 2026, the U.S. Air Force and the Japan Air Self-Defense Force conducted a two-day joint training exercise over the Sea of Japan and the East China Sea, featuring four B-52 strategic bombers. This exercise included three of the Japan Air Self-Defense Force's latest F-3 fighter jets, demonstrating the interoperability and readiness of the Japan-U.S. alliance. The participation of the B-52 bombers serves as a concrete signal of the U.S. commitment to extended deterrence and reflects the heightened tension in the regional security environment.

Moreover, noteworthy is the Japan Maritime Self-Defense Force (JMSDF) undertaking the most comprehensive organizational reorganization since its establishment in 1954, set for March 2026. The "Escort Fleet" will be reorganized from four escort squadrons to three. This reorganization is intended not merely as a reduction in scale but as a transition to a more agile and integrated operational system. It aims to address personnel shortages due to an aging population while simultaneously building an efficient maritime defense capability utilizing more advanced equipment and technology.

Reform of intelligence agencies is also one of the most important proposals in Prime Minister Takaichi's speech. Unlike the United States and the United Kingdom, Japan lacks a central intelligence agency comparable to the CIA or MI5. To address this gap, Prime Minister Takaichi announced plans to establish a "National Intelligence Council" chaired by the Prime Minister and to elevate the Cabinet Intelligence and Research Office to a "National Intelligence Agency." The goal is to better coordinate information resources across ministries, including police and defense agencies, and to protect against foreign interference.

In the realm of economic security, Prime Minister Takaichi proposed the establishment of a Japanese version of the U.S. Committee on Foreign Investment in the United States (CFIUS) to review foreign investments in sensitive areas such as semiconductors, artificial intelligence, and quantum computing. She also promised a review of regulations to restrict foreign land purchases in strategically sensitive areas. These measures are crucial defense lines in a modern context where economic interdependence can translate into security vulnerabilities.

Ensuring supply chain and energy security is also a key pillar of the reform agenda. Prime Minister Takaichi emphasized the need to reduce dependence on "specific countries" in critical supply chains, which is widely interpreted among analysts as referring to China. The vulnerabilities exposed during the COVID-19 pandemic have strengthened Tokyo's resolve to diversify supply sources. Furthermore, she announced cooperation with allies to secure rare earth resources near Minami-Torishima, a remote island in the Pacific. Rare earth elements are essential for high-tech manufacturing, and China currently dominates global production.

Regarding energy policy, Prime Minister Takaichi promised to accelerate the restart of reactors that were halted after the 2011 Fukushima nuclear disaster. While this move has sparked domestic debate, it reflects Tokyo's efforts to balance energy security with decarbonization goals.

Prime Minister Takaichi's reform agenda is supported by strong political authority. Following a decisive electoral victory in February 2026, the ruling coalition holds more than two-thirds of the House of Representatives, providing significant legislative influence. In closing, Prime Minister Takaichi declared, "A country that does not accept challenges has no future. Politics that only seeks to maintain the status quo cannot bring hope."

This comprehensive reform suggests that Japan is entering a new strategic era, shifting from passive defense to proactive security engagement in response to rising regional pressures. As a historic turning point from post-war Japan's pacifist stance, this reform is set to shape the security environment in East Asia for decades to come.
