Japan's Defense Budget Hits ¥10.6 Trillion, Nears NATO's 2% GDP Benchmark

Japan's defense spending is set to surge to ¥10.6 trillion for the fiscal year through March 2027, pushing its military expenditure to 1.9% of GDP. This marks a significant acceleration in the nation's post-war security posture, bringing it to the threshold of the NATO alliance's long-standing 2% spending target—a benchmark historically associated with its Western allies, not Japan.

The planned budget represents a concrete step in the execution of Japan's new National Security Strategy, which was revised in late 2022 to authorize a dramatic military buildup over five years. The move to near 2% of GDP underscores a fundamental shift from Japan's traditionally constrained defense posture, driven by heightened regional security concerns, particularly regarding China's military expansion and North Korea's missile programs.

This level of expenditure places Japan among the world's top military spenders and signals a deepening alignment with its security partners, primarily the United States. The sustained financial commitment pressures domestic fiscal policy, given Japan's substantial public debt, and will likely intensify scrutiny over the allocation and efficiency of the massive new funds for capabilities like long-range counterstrike missiles.
