TOKYO: Japan’s defense spending and related costs for fiscal 2026 will total about 10.6 trillion yen, or roughly 1.9% of the country’s 2022 gross domestic product, Defense Minister Shinjiro Koizumi said on Friday, putting the latest budget cycle near a level that had been set out as a key benchmark in Japan’s 2022 security strategy. The figure covers the fiscal year that began on April 1 and reflects the government’s latest accounting of defense outlays and associated spending.
Ministry of Defense budget documents for fiscal 2026 show defense-related expenditures of 8.8093 trillion yen, up 3.9% from the previous year. That total rises to 9.0353 trillion yen when SACO- and U.S. forces realignment-related expenses are included. The ministry also said the expenditure budget for implementing the Defense Buildup Program stands at 8.809 trillion yen, while the contract budget amounts to 8.261 trillion yen, laying out the core spending plan for the year under the current buildup framework.
The fiscal 2026 plan builds on the National Security Strategy, National Defense Strategy and Defense Buildup Program adopted in 2022. In its latest budget overview, the Ministry of Defense said the government had brought forward the goal of reaching a defense budget level equivalent to 2% of GDP to fiscal 2025 through a combination of initial and supplementary budgets. An official chart in the same budget materials shows fiscal 2026 marking the 14th consecutive annual increase in Japan’s initial defense budget on a broader measure, reaching a record 9.04 trillion yen.
Japan spending priorities shift to missiles, air defense and drones
A large share of the new spending remains focused on missiles and air defense. The budget allocates about 973.3 billion yen on a contract basis for stand-off defense capabilities, including upgraded Type-12 missiles, submarine-launched missiles, hypersonic weapons programs and vessel upgrades tied to Tomahawk launch functions. Another 509.1 billion yen is allocated for integrated air and missile defense capabilities, covering projects designed to strengthen responses to ballistic and hypersonic threats and to expand the architecture needed for detection, tracking and interception.
Unmanned systems and personnel measures also feature prominently in the fiscal 2026 plan. The ministry’s budget materials show about 277 billion yen for unmanned defense capabilities, while a separate section allocates about 100.1 billion yen in fiscal 2026 toward establishing SHIELD, a synchronized littoral defense concept using unmanned assets, by fiscal 2027. The Ministry of Defense also set aside 581.4 billion yen for measures aimed at strengthening the human resource base, including improvements in treatment and working conditions, as the Self-Defense Forces face what the ministry describes as a severe recruitment environment.
Funding questions remain as implementation moves ahead
The budget package also includes a financing element that extends beyond procurement and force structure. In its tax-system reform section, the ministry said a 1% income tax surtax will be imposed from January 2027, while the special income tax for reconstruction from the Great East Japan Earthquake will be reduced by 1% to avoid an increase in the burden on households at the time of introduction. The ministry also said it would keep monitoring project allocations across 15 budget areas and continue cost reviews and procurement scrutiny in light of the weak yen and higher prices.
Koizumi’s update provides the clearest current snapshot of Japan’s fiscal 2026 defense posture as the new budget year gets under way. While the 1.9% figure refers to defense spending and related costs rather than the narrower core budget line, the underlying budget documents show a broader rise in spending across missiles, air and missile defense, unmanned systems, infrastructure and personnel. Taken together, the figures show fiscal 2026 opening with Japanese defense spending close to a level that had previously been framed as a longer-term target. – By Content Syndication Services.
