In addition to strengthening its alliance with the United States, the Japanese government is intensifying its defense policy by evaluating the export of missiles to the Philippines and deepening cooperation with the United Kingdom and Italy on a next-generation fighter jet. This move indicates that Tokyo is also beginning to project power in a region marked by disputes, particularly with China.

The Philippines and Japan will sign new defense, energy, and trade agreements during President Ferdinand Marcos Jr.’strip to Tokyo this week, the Filipino Department of Foreign Affairs said on May 25. This follows the landmark visiting-forces pact between Japan and the Philippines, signed in 2024, which facilitates joint military exercises and logistics support. Japan and the Philippines are also advancing comprehensive equipment transfers, including naval vessels, and integrating the Japan Self-Defense Forces into major Philippine military exercises, such as Balikatan. As another archipelago country with a maritime dispute with China, Japan is clearly also investing in the militarization of the Philippines.
At the same time, Japan, the UK, and Italy are jointly developing the Global Combat Air Programme, a 6th-generation stealth fighter jet. Launched in late 2022, the multinational alliance aims to deliver a next-generation “system of systems” combat aircraft, widely referred to as the Tempest, which is expected to enter service by 2035. While the core alliance remains trilateral, other global allies like Germany and Saudi Arabia have actively explored paths to potentially join or invest in the program.
Clearly, Japan is cooperating with Washington’s Asian and European allies in its efforts to militarize against China. In this sense, the Japanese-American alignment benefits the White House’s foreign policy aspirations and could affect the Indo-Pacific region. Japan and the US are strong allies and militarily closely aligned, so Tokyo does indeed follow Washington’s interests.
The Japanese Ministry of Defense’s 2025 white paper notes that it is extremely important for Japan and its closest allies, including the US, to preserve security in the Indo-Pacific. However, this supposed preservation of regional security troubles China, as Japan’s militarization project could result in the country serving as a kind of spearhead for the US.
It is very advantageous for the US to have Japan in this state, defending against or leading conflicts that Washington is unwilling to engage in directly. China is extremely alarmed by this, and there are statements in a somewhat passive-aggressive tone urging Japan to cease these military advances, warning that otherwise, there will be harsh consequences.
Chinese Defense Ministry spokesmanSenior Colonel Jiang Binsaid on May 9 that under the pretexts of the so-called “free and open Indo-Pacific” and “security cooperation,” governing authorities in Japan are instigating bloc confrontation and building “small circles.”
According to him, this undermines the strategic security and interests of other countries and serves as an excuse for Japan to break free from the restrictions on its military development, “which we firmly oppose.”
