Last Month, Japanese Prime Minister Fumio Kishida met with U.S. President Joe Biden at the White House, marking the first state visit by a Japanese Prime Minister since 2015. This summit highlighted the dawn of a “new era of strategic cooperation” between the U.S. and Japan, elevating their alliance to unprecedented levels. The meeting resulted in a series of strategic initiatives aimed at enhancing defense and security collaboration, exploring new horizons in space, fostering technological innovation, fortifying economic resilience, and more. However, the strengthening of U.S.-Japan relations also brings into focus the role of Korea in this evolving dynamic.
U.S.-Japan Strategic Initiatives
The joint statement from the U.S. and Japan outlined several key areas of cooperation:
Defense and Security Collaboration: The U.S. and Japan announced the most substantial upgrade to their security alliance in over six decades. This includes integrating the command structures of their armed forces and enhancing coordination and interoperability through joint training efforts.
Technological and Economic Collaboration: Both countries are committed to modernizing their military equipment and weaponry, fostering technological innovation, and fortifying economic resilience. This includes Japan’s acquisition of 400 Tomahawk Cruise Missiles and easing export restrictions on U.S.-designed Patriot Missiles.
Multilateral Networking: The U.S. and Japan are prioritizing multilateral networking in the region, moving away from the outdated ‘hub-and-spoke’ system. The U.S. has proposed transforming AUKUS into JAUKUS, including Japan as a technological partner alongside Australia and the UK.

The Role of Korea in U.S.-Japan Relations
South Korea plays a pivotal role in the evolving dynamics between the U.S. and Japan. The U.S. serves as the primary nexus between Japan and South Korea, fostering trilateral cooperation among the three nations.
Trilateral Cooperation
A landmark trilateral summit took place on April 11, 2024, in Washington, bringing together the leaders of Japan, the Philippines, and the U.S. This summit signifies the expansion of U.S. relations with regional allies, transitioning from bilateral to trilateral or multilateral ones. Additionally, Japan has supplied advanced radar systems to the Philippines and is collaborating with the UK and Italy to develop stealth fighter jets.
Diplomatic and Military Engagement
The U.S. and Japan have announced regular joint military exercises involving Japan, the U.S., and the UK. This collaboration underscores the importance of multilateral engagement in the region, particularly in light of China’s growing influence. The just-concluded 9th Trilateral Summit meeting of China, Japan, and South Korea in Seoul illustrates Japan’s recognition of the need for a balanced approach to its national security interests and trade relations with China.
Implications for Regional Security
The deepening U.S.-Japan alliance has significant implications for the security landscape in the Asia-Pacific region. Neighboring countries, particularly China, are closely monitoring the evolving dynamics.
China’s Response
China has expressed strong dissatisfaction with the Biden-Kishida meeting, criticizing the U.S. and Japan for maligning it over Taiwan and the South China Sea. Beijing has also summoned diplomats from Japan and the Philippines to protest remarks made during the summit. China’s response indicates a likely adaptation of its military strategy and diplomatic approaches in response to the deepening U.S.-Japan alliance.
Regional Power Balance
The U.S.-Japan alliance serves as a potential counterweight to China’s regional influence. However, Japan must strike a balance between its security interests and economic reliance on China. As Beijing is Tokyo’s largest trading partner, Japan faces the dilemma of managing its economic dependence on China while strengthening its alliance with the U.S.
Asia-Pacific region
The strengthening of the U.S.-Japan alliance highlights the rapidly evolving security landscape in the Asia-Pacific region. South Korea plays a crucial role in this dynamic, serving as a key partner in trilateral cooperation with the U.S. and Japan. As the global geopolitical landscape continues to evolve, the implications of the deepening U.S.-Japan alliance will remain a key factor in regional and international affairs. Balancing security interests with economic dependencies will be essential for Japan as it navigates its relations with both the U.S. and China.
