# Japan's Next Defense Budget Leans Hard Into Drones and AI to Counter China > A 55.6 billion dollar spending request from Defense Minister Shinjiro Koizumi's ministry lays out plans for cheap mass produced attack drones, an AI command platform and submarine launched hypersonic missiles, all aimed at offsetting China's growing military footprint with fewer troops on hand to match it. - Source: Morning Sun - Canonical URL: https://morningsun.jpn.com/article/japan-s-next-defense-budget-leans-hard-into-drones-and-ai-to-counter-china - Author: Morning Sun Editorial - Section: Japan - Published: 2026-09-03T20:50:35.811Z - Updated: 2026-09-03T20:50:35.811Z - Tags: Japan, China, Shinjiro Koizumi, Defense, Drones, Artificial Intelligence, Hypersonic Missiles, Self-Defense Forces, Military --- Japan's Defense Ministry has laid out an eight point nine trillion yen budget request, worth roughly fifty five point six billion dollars, for the fiscal year beginning in April 2027, detailing a defense buildup that leans heavily on unmanned systems and artificial intelligence rather than simply adding more personnel. The request marks only a modest increase over the current eight point eight trillion yen budget, with officials signaling that larger jumps in spending are likely once the government finalizes a new national security strategy later this year. Defense Minister Shinjiro Koizumi submitted the underlying assessment to the cabinet earlier this year, and the document leaves little doubt about where the ministry's priorities now sit. Rather than treating drones and AI as add ons to a conventional force structure, the plan positions them as central to how Japan intends to fight and deter conflict going forward, a shift driven as much by demographics as by the immediate threat picture. ## Cheap drones instead of expensive planes At the center of the plan is a push to develop and mass produce low cost attack drones capable of launching from both the air and from submarines, paired with long range missiles to create a more affordable strike network. The logic is straightforward: expensive, exquisite platforms take years to build and put pilots and crews at risk, while a swarm of cheaper uncrewed weapons can absorb losses and still get the job done. Japanese officials have acknowledged one significant obstacle to that plan, though, noting that the country's own commercial drone market is currently dominated by imports from China, the very rival the buildup is meant to counter. The ministry also wants hypersonic missiles capable of being fired from submarines, a capability meant to strengthen Japan's ability to strike back at long range if deterrence fails, adding a harder to detect launch platform to a strike capability Tokyo has been building out for several years. ## Putting AI in the command chain Beyond weapons platforms, the ministry is planning an integrated artificial intelligence system for command and control, intended to speed up decision making and give commanders a faster read on a fast moving battlefield. The approach blends existing foreign technology, including systems developed in the United States, with continued investment in homegrown AI capability, a hedge that lets Japan field useful tools quickly while it builds out its own expertise over time. A companion Defense Ministry cloud is also planned to carry sensitive data and keep communications running during a crisis. ## Securing the supply chain at home On the industrial side, the government intends to set up a state owned, contractor operated system meant to guarantee steady production of defense equipment, an arrangement that would have the state acquire factories and then hand day to day manufacturing to private companies. The goal is to avoid the kind of production bottlenecks that have hampered other countries' efforts to rearm quickly, ensuring that a surge in orders does not simply outrun the factories capable of filling them. ## The demographic math behind the shift Much of the emphasis on unmanned systems traces back to a problem money alone cannot fix: Japan's shrinking population is steadily shrinking the pool of people available to serve in uniform. Leaning on drones and AI lets the Self Defense Forces field more combat capability without needing to recruit proportionally more people, a trade off that is likely to become only more important as the country's demographic trends continue. The broader posture continues a shift that began with Japan's 2022 defense strategy, under which the country roughly doubled defense spending to around two percent of gross domestic product. This year's defense white paper described China's expanding military activity in the Pacific as Japan's greatest strategic challenge, language Beijing has dismissed as an example of what it calls Japanese new militarism, even as Tokyo continues building out the drone and AI capabilities it says are necessary to keep pace. --- Originally published by Morning Sun.
