Japan's Cabinet Approves Historic ¥9 Trillion Defense Budget for 2026

On Friday, Japan's Cabinet approved a historic defense budget exceeding 9 trillion yen ($58 billion) for the upcoming fiscal year, emphasizing a crucial shift towards bolstering military capabilities amidst escalating regional tensions.

The proposed budget for fiscal year 2026, which begins in April, signifies a 9.4% rise from 2025 and continues Japan's five-year plan to ramp up annual defense spending to 2% of GDP. If ratified by parliament, this initiative will position Japan as one of the leading military spenders globally.

Prioritizing Missiles and Coastal Defense

A significant portion of the new investment will be dedicated to reinforcing Japan's “strike-back” capabilities, marking a pivotal transformation from post-World War II policies that restricted military engagement to self-defense.

The allocation includes over 970 billion yen ($6.2 billion) to enhance long-range missile capabilities, featuring an investment of 177 billion yen ($1.13 billion) for upgraded Type-12 surface-to-ship missiles. These missiles will boast a range of approximately 1,000 kilometers, with the first deployment scheduled in Kumamoto by March, a year earlier than planned.

Japan's southwestern islands, perceived as strategically susceptible, are a focal point in the missile enhancement initiative.

Increased Focus on Drones

In response to an aging population and shortages in military personnel, the government is increasingly turning to unmanned systems. The budget allocates 100 billion yen ($640 million) for deploying a multitude of unmanned aerial, surface, and underwater drones to fortify coastal surveillance and defense.

These unmanned systems will operate under a new initiative named “SHIELD,” set to launch by March 2028, with an initial reliance on imported systems from countries such as Turkey and Israel.

China as a Key Strategic Concern

Japan’s current security framework, established in 2022, designates China as its prime strategic challenge. Tensions have escalated particularly in relation to Taiwan and intensified Chinese military maneuvers near Japanese airspace.

In November, Prime Minister Sanae Takaichi indicated Japan's potential involvement should China act against Taiwan, provoking strong responses from Beijing.

Relations deteriorated this month following Chinese aircraft carrier exercises near southwestern Japan, leading Tokyo to complain after Chinese jets reportedly locked radar onto Japanese planes, an action perceived as a possible precursor to missile targeting.

In light of these developments, Japan’s Defense Ministry aims to establish an office dedicated to monitoring China's escalating military activities across the Pacific.

Strengthening Defense Industry and Collaborative Development

Japan is also working to bolster its defense industry through international collaborations. The 2026 budget includes over 160 billion yen ($1 billion) aimed at joint development of a next-generation fighter jet with Britain and Italy, expected for deployment in 2035. Research efforts are also underway for AI-driven drones designed to complement the aircraft.

A significant boost for Japan's defense manufacturing sector came when Australia chose Mitsubishi Heavy Industries in August for the upgrade of its Mogami-class frigates, replacing the aging ANZAC-class fleet.

Additionally, approximately 10 billion yen ($64 million) has been set aside to support the defense industry and promote international arms sales, following Japan's recent relaxation of export limitations.

Funding and Future Challenges

This defense budget will be part of a broader national budget bill amounting to 122.3 trillion yen ($784 billion) that must secure parliamentary approval by March. If enacted, Japan's annual defense expenditures will rise to around 10 trillion yen, positioning it as the third-largest defense spender after the U.S. and China.

While the government intends to finance this military expansion through increased corporate and tobacco taxes, alongside anticipated income tax hikes from 2027, concerns persist regarding the viability of sustaining such increases beyond the 2% GDP benchmark.

Nevertheless, this latest budget reflects Japan's resolute commitment to swiftly enhance its military stance amid growing security apprehensions in East Asia.
