Japan’s Ministry of Defense has proposed acquiring roughly 52,000 unmanned systems during the five-year period beginning in fiscal 2027, according to a preliminary draft of its defence development programme reported by Kyodo News. The document is one of three key security-policy papers that Prime Minister Takaicsi Szanae’s government intends to review by the end of the year.
Why the shift?
The proposal is motivated by what Tokyo describes as growing regional threats: increased Chinese military activity, lessons from the Russia–Ukraine war, and North Korea’s nuclear and missile programmes. The plan aims to strengthen Japan’s long-range strike capabilities and its deterrent posture.
Allocations and planned procurements
The draft sets out large spending priorities and specific procurement goals:
- More than 9 trillion yen (about 58 billion USD) for enhancing strike capabilities, including long-range missiles able to target enemy bases.
- Approximately 7 trillion yen for artificial intelligence and unmanned systems, six times the current budget for those areas.
- An estimated 8 trillion yen to upgrade air-defence networks, which would include deploying next-generation railguns (electromagnetic weapons capable of launching projectiles at very high velocities).
- About 10 trillion yen set aside to prepare for a protracted conflict, including stockpiling one year’s worth of ammunition, rockets and fuel.
On the force-structure side, the document details planned buys from the more than 52,000 unmanned systems:
- Around 10,000 long-range, land-attack strike drones.
- About 1,300 systems dedicated to anti-ship defence.
- Roughly 7,500 platforms for reconnaissance and surveillance (ISR).
The plan also envisages starting mass production of hypersonic missiles and expanding a small-satellite constellation used to detect and track targets to roughly 100 satellites.
Projected total spending and financing challenges
Senior government officials cited in the draft estimate that defence expenditures over the next five-year cycle could reach 70–80 trillion yen, a substantial rise from the 43 trillion yen budgeted for 2023–2027. Given Japan’s high public debt, raising the necessary funds represents a significant fiscal challenge.
Next steps
The document is currently a preliminary blueprint; final decisions will depend on the government’s review and political approvals to be completed by year-end. Nevertheless, the draft signals that Japan intends to undertake a substantial capability expansion focused on long-range strike, unmanned systems and integrated air-defence improvements.
Summary
Kyodo News’s reporting on the draft plan indicates that Japan is preparing to dramatically increase defence spending and to procure tens of thousands of unmanned systems from fiscal 2027 onward. The measures are driven by regional security concerns but will require major financing choices given the country’s existing fiscal constraints.
