What North Korea accused Japan of doing

North Korean state media presented the spending increase as evidence that Japan is moving away from its postwar security posture and rebuilding offensive military power. Its rhetoric invoked Japan’s wartime past, portraying the country’s expanding capabilities as a revival of militarism rather than a response to current security risks.

Pyongyang specifically objected to Japan’s acquisition and testing of U.S.-made Tomahawk cruise missiles. Kim Yo Jong had already warned in early August that Japan’s transformation into a military power, backed by Washington, could prompt North Korea to adopt “additional military options.” Reuters reported that analysts viewed the statement as potentially helping Pyongyang justify future weapons development and testing.

North Korea also criticized Japan’s broader shift toward long-range and “counterstrike” capabilities. Japan’s defense plans include research into submarine-launched hypersonic missiles, long-range missiles and drones, as well as AI-enabled command-and-control systems.

The threat from Pyongyang

The latest statement did not announce a specific operation or weapons test. Instead, North Korea issued a broad warning that the international community would not tolerate Japan’s military expansion and would “thoroughly counter” it with a united response.

Kim Yo Jong’s earlier statement was more explicit about the possibility of future action, warning that North Korea’s leadership would establish “additional military options” in response to Japan’s expanding strike capabilities. That language leaves the precise form and timing of any response unclear.

Claims attributed to Pyongyang about Japan spending heavily despite record national debt should be treated as political rhetoric. The available reporting establishes North Korea’s condemnation of the budget and its weapons-related accusations, but does not independently verify a specific North Korean debt figure or formulation.

How the request fits Japan’s defense buildup

Japan’s FY2027 request is the final year of a five-year defense program approved for FY2023–27. The program was designed around roughly ¥43 trillion in defense spending and a goal of bringing defense-related outlays toward 2% of GDP by 2027.

The policy reflects Japan’s assessment that security risks from China, North Korea and Russia have become more serious. Defense Minister Shinjiro Koizumi has described the regional environment as the most severe and complex Japan has faced in the postwar era, while defending cooperation among Japan, the United States and South Korea as important to regional peace and stability.

The systems under discussion help explain why Pyongyang characterizes the buildup as offensive. Tomahawk missiles and other long-range weapons can extend Japan’s ability to strike targets beyond its immediate territory, while drones and AI-supported command systems are intended to improve surveillance, coordination and operational resilience. Japan describes these capabilities as part of its deterrence and defense strategy; North Korea presents them as preparation for aggression.

The evidence provided does not establish that Prime Minister Sanae Takaichi abolished all spending caps. Reporting does indicate that Japan’s wider FY2027 budget process includes a newly created growth-investment category without a spending cap, but that is not the same as proving that every limit on defense spending was removed.

Why the regional context matters

North Korea’s response came during a period of uncertainty over the U.S.-South Korean alliance. Washington and Seoul shortened the 2026 Ulchi Freedom Shield exercise from its planned 11 days to five at the U.S. side’s request, while some field training was also reduced.

President Donald Trump said the exercises sent an “inappropriate and hostile” signal to North Korea, and reporting indicated that he was seeking a possible meeting with Kim Jong Un. South Korea, meanwhile, emphasized that its alliance with the United States remains foundational to national security after the abrupt change.

That combination creates a complicated regional signal. Japan is expanding its independent strike and command capabilities, North Korea is using the buildup to reinforce its militarism narrative, and the United States is simultaneously adjusting the scale of exercises with South Korea while pursuing possible engagement with Pyongyang.

The central dispute

The disagreement is ultimately about the meaning of Japan’s military expansion. Tokyo sees a deteriorating security environment and argues that stronger capabilities and closer coordination with Washington and Seoul are necessary for deterrence. Pyongyang sees the same developments—especially Tomahawks, long-range missiles and trilateral security cooperation—as proof that Japan is becoming an offensive military power.

North Korea’s latest threat therefore functions both as a warning and as political messaging. It condemns the ¥8.9 trillion request, invokes Japan’s wartime history and leaves open the possibility of further military measures, without specifying what action would follow. The unresolved question is whether Japan’s buildup will strengthen deterrence or deepen the cycle of threat, rearmament and counter-threat across Northeast Asia.
