The Japanese government reiterated its dedication to strengthening its military alliance with the United States on Friday, following reports suggesting that the Pentagon might reconsider plans to expand U.S. Forces Japan (USFJ). This development comes amid broader discussions on defense strategies in the Indo-Pacific region.
The United States maintains approximately 54,000 military personnel in Japan, primarily reporting to the Indo-Pacific Command based in Hawaii. In July 2024, a significant shift was announced: the U.S. intended to transform USFJ into a joint force headquarters, directly reporting to the commander of the Indo-Pacific Command. This restructuring aimed to enhance operational efficiency and strengthen the bilateral defense posture.
Recent reports from CNN and NBC News indicate that the Trump administration is contemplating halting the planned expansion of USFJ as part of a comprehensive cost-cutting initiative. The proposed move could save approximately $1.1 billion but might also entail political risks in Japan and diminish U.S. command capabilities in the Pacific.
Japan’s Chief Cabinet Secretary, Yoshimasa Hayashi, addressed these reports, emphasizing that there has been “no change” to the bilateral agreement aimed at enhancing deterrence capabilities under the U.S.-Japan alliance. He stated, “We want to continue close discussions between Japan and the United States to further strengthen the interoperability and responsiveness of our two militaries.” Hayashi refrained from commenting on whether the U.S. had officially communicated any changes to Japan.
In line with bolstering its defense capabilities, Japan has embarked on a multi-year plan to increase its defense spending to approximately 2% of its gross domestic product (GDP), aligning with NATO standards. This initiative reflects Japan’s commitment to enhancing its self-defense mechanisms amid evolving regional security dynamics.
The U.S. military presence in Japan, particularly in Okinawa, has been a sensitive topic. Local communities have expressed concerns over incidents involving U.S. personnel, including crimes and accidents. These incidents have occasionally strained relations and fueled debates about the U.S. military footprint in the region.
The Indo-Pacific region faces increasing security challenges, notably from China’s assertive actions and North Korea’s missile programs. In response, Japan has announced plans to deploy long-range missiles with a 1,000 km range on its southern island of Kyushu. This deployment aims to bolster defenses of Okinawa and counter regional threats. The missiles are scheduled for deployment next year at existing garrisons on Kyushu, deliberately avoiding Okinawa to prevent escalating tensions with China.
The return of President Donald Trump has introduced uncertainties in traditional U.S. alliances. Japan, historically reliant on U.S. military support, now faces the challenge of adapting to an “America First” approach. This shift necessitates Japan to reassess its defense policies and explore deeper collaborations with regional democracies to ensure its security amidst a rising authoritarian China.
To maintain robust U.S. military support, Japan is considering substantial investments in U.S. industries. A notable proposal includes a $1 trillion investment in sectors such as defense and artificial intelligence. These economic initiatives aim to solidify U.S. military assistance in the region, reflecting a strategic approach to alliance management.
The election of Shigeru Ishiba as Japan’s Prime Minister has implications for the nation’s defense strategy. Known for his hawkish stance, Ishiba advocates for rebuilding Japan’s military capabilities and amending its pacifist constitution. His vision includes a more balanced security relationship with the U.S. and the formation of an “Asian NATO” to counter China’s influence.

Japan’s defense strategy also encompasses strengthening trilateral military relations with allies like Australia and the U.S. Plans are underway to deploy Japanese soldiers to the Northern Territory of Australia, enhancing interoperability and regional security. A regiment-sized force of approximately 600 Japanese troops is expected to rotate through the region during major exercises, underscoring Japan’s commitment to collaborative defense efforts.
Japan remains steadfast in its commitment to the U.S. military alliance, even as discussions about command structure changes and financial considerations emerge. The evolving geopolitical landscape necessitates continuous dialogue and collaboration to ensure regional stability and address emerging security challenges.
