MANILA — Japan will provide the Philippine Navy with a coastal radar system and the Philippine Air Force with surveillance drones under a ¥4.3 billion (yaani 430 crore yen; about PHP1.72 billion, roughly $27 million) security grant signed by the two countries on Monday, November 9, the Philippine News Agency reported.

Foreign Affairs Secretary Maria Theresa Lazaro and Japanese Ambassador to the Philippines Kitagawa Katsuro signed and exchanged notes at the Department of Foreign Affairs headquarters in Pasay City for the fiscal year 2026 project under Japan's Official Security Assistance (OSA) programme, BusinessMirror reported. Japan's Ministry of Foreign Affairs said the coastal radar system, classified as defence equipment, marks the first transfer of such equipment under the OSA programme.

"The largest OSA grant" — and the first defence equipment

"Today's grant, amounting to ¥4.3 billion, is the largest OSA grant since the framework's establishment, as well as the first defense equipment transfer under Japan's OSA program," Ambassador Kitagawa said at the signing. Koh Nakamura, First Secretary of the Japanese Embassy, told reporters the package differs from the coastal radars Japan provided earlier: "This time is military grade, so that's the difference." He stressed that the assistance is "a grant," not a loan.

Nakamura said the equipment is meant to help the Philippines safeguard its interests in the South China Sea and on the northern and western sides of Luzon, the country's largest island. Where the radars are deployed will be decided by Philippine defence authorities: "In the end, it's up to them where to put those radars," he said. Delivery is expected to take two to three years because the procurement must go through standard tender and bidding.

Why Tokyo is doing this

Japan's foreign ministry cited the Philippines' strategic location near key maritime routes, including the South China Sea and the Luzon Strait — the passage between Taiwan and northern Luzon that links the South China Sea to the Pacific — and described Manila as a "Comprehensive Strategic Partner" under Japan's updated Free and Open Indo-Pacific policy. The ministry said the project is expected to deepen bilateral security cooperation, enhance the security of sea lanes vital to Japan and contribute to regional peace and stability. The radar system and drones are expected to strengthen the Armed Forces of the Philippines' maritime domain awareness and surveillance capability.

Secretary Lazaro said Tokyo and Manila share the same view of the region: "Japan and the Philippines look at the region and see the same principles worth protecting: freedom of navigation and overflight, peaceful settlement of disputes, and respect for sovereignty and territorial integrity." She called the signing "another concrete demonstration of this platinum era of relations," following the elevation of ties to a comprehensive strategic partnership, and said it "affirms that capacity-building efforts by the Philippines are investments in regional peace and stability."

Background: the Philippines is OSA's first — and only multi-year — recipient

The Philippines was the first recipient of OSA when the programme began in 2023, receiving ¥600 million for five coastal radar systems that year, with the Navy as end user; those systems were delivered in January 2026. A ¥1.6 billion package followed in December 2024 for the Navy and the Air Force, and in January 2026 Japan signed a ¥900 million project to build boathouses and slipways for rigid-hulled inflatable boats. The Philippines is the first and only multi-year recipient of the programme. The OSA framework, launched in 2023, provides grants for equipment, supplies and infrastructure to the armed forces of partner countries to strengthen their security and deterrence capabilities.

What is solid

  • The grant was signed in Manila on Monday, November 9, by Secretary Lazaro and Ambassador Kitagawa — ¥4.3 billion for a Navy coastal radar system and Air Force surveillance drones
  • Japan's foreign ministry classifies the radar as defence equipment and calls this the first such transfer under OSA; the ambassador called it the programme's largest grant to date
  • The assistance is a grant, not a loan, and the new radar is military-grade, unlike the earlier civilian dual-use sets

What is only claimed

  • No delivery date has been set — officials estimate two to three years, so the package does not change the balance at sea now
  • Deployment sites for the radars have not been chosen; Philippine defence authorities will decide
  • China, which claims almost the entire South China Sea and contests the waters this equipment will watch, had not commented on this specific grant in the reports checked at publication

What happens next

The project now moves into procurement under standard tender and bidding, with delivery expected over the next two to three years. The signing lands as Manila and Tokyo deepen defence ties across the region's contested waterways — and as both governments frame maritime surveillance, rather than new weapons, as the front line of deterrence in the South China Sea and the Luzon Strait.
