Key Insights• Japan’s precision-guided munition market is undergoing a historic transformation driven by the most significant defence buildup since World War II. Japan’s FY2026 defence budget reached a record 9.04 trillion yen, marking the 14th consecutive annual increase. Defence spending has grown 67% since FY2022, with equipment procurement expenses expanding 2.1 times. Japan achieved the NATO 2% GDP defence spending target in FY2025 two years ahead of schedule and total defence-related spending for FY2026 is approximately 10.6 trillion yen.• Japan is simultaneously pursuing a dual-track strategy, acquiring cutting-edge precision-guided munitions from international partners including up to 400 Tomahawk cruise missiles ($2.35 billion), 66+ JASSM-ER long-range cruise missiles, SM-6 Block I missiles ($900 million), and Joint Strike Missiles from Norway while investing heavily in domestic precision strike capabilities through the upgraded Type-12 missile, the HVGP hypersonic glide vehicle, submarine-launched missiles, and new surface-to-surface precision-guided missiles developed by Mitsubishi Heavy Industries.• Stand-off defence capabilities received over $6.2 billion in the FY2026 budget approximately 12% of the total defence budget and a 9% year-on-year increase representing Japan's single largest investment category. Key programmes include upgraded Type-12 missiles, submarine launched missiles, hypersonic weapons, and vessel upgrades for Tomahawk launch functions.Market Outlook• According to the research report, "Japan Precision-Guided Munition Market Outlook, 2031," published by Actual Market Research, the Japan Precision-Guided Munition Market is anticipated to grow at more than 7.62% CAGR from 2026 to 2031.• Integrated air and missile defence capabilities received ¥509.1 billion in FY2026, covering projects designed to strengthen responses to ballistic and hypersonic threats and expand the architecture needed for detection, tracking, and interception. About ¥517.4 billion is planned for reinforcement of air defence capabilities by improving missile detection and tracking systems.• Unmanned systems and loitering munitions are emerging as significant growth segments.

Japan allocated ¥312.8 billion to purchase aerial and underwater drones, approximately ¥277 billion for unmanned defence capabilities, and ¥100.1 billion toward establishing the SHIELD layered coastal defence system by FY2027. Japan’s defence white paper explicitly calls for broader application of "new forms of warfare," including drones and artificial intelligence.Policies & Regulatory Landscape • Japan’s defence procurement operates under the Defense Buildup Program, formulated by the National Security Council and approved by the Cabinet on December 16, 2022. FY2026 marks the fourth year under the DBP, with the Ministry of Defense requesting programmes needed to fundamentally reinforce Japan's defence capabilities by FY2027.• Japan achieved the 2% GDP defence spending target in FY2025 two years ahead of the original FY2027 schedule through a combination of initial and supplementary budgets. The government has committed to 43 trillion yen in defence spending over five years (FY2023-FY2027). Prime Minister Takaichi has expressed an intention to further accelerate defence spending increases.• Japan has loosened arms export controls to enable the sale of Patriot missiles made in Japan under licence to the United States, which is replenishing stocks depleted by support to Ukraine. The ruling Liberal Democratic Party and its coalition partner are arranging talks on revising Japan's three security documents, including potentially abolishing categories of exportable defence equipment.• The Japan Acquisition, Technology & Logistics Agency (ATLA) manages defence procurement and technology development.

The Ministry of Defense is promoting efficient procurement through bulk purchase and long-term contracts, while carefully examining costs in light of the weak yen and high prices. PGM Procurement & Industry Impact• Japan is acquiring up to 400 Tomahawk cruise missiles from the United States under a $2.35 billion contract. The Tomahawk has a 1,600-kilometre range. Japan signed the contract in 2024, with deliveries scheduled between FY2025 and FY2027. Japan has set aside $1.5 billion to buy the missiles. The missiles will equip Japan's eight Aegis destroyers, beginning with JS Chokai, which is undergoing in the United States. Japan’s defence chief confirmed in May 2026 that the delivery schedule remains on track.• Japan is acquiring Joint Strike Missiles (JSM) from Norway's Kongsberg Defence & Aerospace.

The JSM is a fifth generation stealth air-to-ground missile that can be carried internally in the F-35A without compromising the aircraft’s low-signature capabilities. Japan signed its fifth follow on contract worth approximately €70 million, and deliveries began in March 2026. The JSM will equip JASDF F-35A fighters and features GPS, inertial navigation, infrared seekers, and UHF two-way data link for mission updates and target changes.• Japan is acquiring Standard Missile 6 Block I missiles. The US State Department approved a possible $900 million Foreign Military Sale on January 31, 2025. The SM-6 provides enhanced air and missile defence capabilities against ballistic and hypersonic threats. Industry News • Lockheed Martin is the principal contractor for the JASSM-ER programme, responsible for missile production, integration support, and technical services.
