The US-Japan alliance keeps China from bullying the world into higher prices

That framework didn’t start in Washington. Japan first advanced the concept of a free and open Indo-Pacific, and the region later adopted it through partnerships such as the Quad — the informal grouping of the United States, Japan, India, and Australia.
Rather than announcing a new direction, the NSS reinforces a familiar one: Alliances form the core of deterring China. Unlike the Trump playbook in Ukraine, the administration treats alliances as the bedrock of Indo-Pacific security against Beijing’s expanding military reach.
Japan sits at the heart of that network.
China pressures Japan across its waters and airspace, making Tokyo a frontline state. Japan also serves as the United States’ indispensable partner in the region, with basing, interoperability, and shared strategy that no other ally can match at the same scale. Under new conservative leadership, Japan has begun acting with urgency.
Japan’s defense minister, Shinjiro Koizumi, has emphasized that urgency, warning that the country now faces its most severe security environment since World War II. Japan has deepened coordination with the U.S. and other like-minded partners while strengthening its military capabilities by accelerating security reforms and easing restrictions on defense equipment transfers.
Japan has also moved up its plan to raise defense spending to 2% of GDP — from 2027 to now. That headline matters less than where the money goes.
Tokyo has prioritized capabilities suited for a long-term, high-risk environment: unmanned aerial vehicles, expanded surveillance platforms, and submarines equipped with vertical-launch missile systems.

Japan’s objective looks straightforward. It aims to become a more capable military partner that complements U.S. forces rather than relying on them by default. That shift aligns with President Trump’s demand that allies reduce dependence on American power by strengthening their own defense industries and readiness.
The U.S.-Japan alliance has also moved beyond drills and declarations toward defense-industrial cooperation. Expanded maintenance and repair coordination, along with eased export controls, have begun laying the groundwork for a durable security partnership.
This collaboration marks a shift from rhetoric to endurance. Aligning strategy with industrial capacity won’t eliminate risk. It will raise the cost of Chinese coercion and reduce the chances that Beijing miscalculates.
Koizumi has stressed that 80 years after World War II, the U.S.-Japan alliance still embodies reconciliation and remains the best instrument to deter China’s rising aggression.
If Washington and Tokyo keep strengthening this partnership — in capability, production, and resolve — they can make the Indo-Pacific more difficult for Beijing to bully and far more stable for everyone who depends on it.
