A new military logistics agreement between the Philippines and Japan marks an initial step toward deeper defense cooperation and will extend the operational reach of their armed forces, a Philippine military official said Wednesday.
The Acquisition and Cross-Servicing Agreement, or ACSA, took effect Aug. 22. It allows the two countries’ militaries to exchange logistical support, supplies and services during exercises, training and other agreed activities.
Retired Rear Adm. Roy Vincent Trinidad, the Armed Forces of the Philippines’ special spokesperson for the West Philippine Sea, said the agreement would strengthen logistics and sustainment operations across the Philippine Army, Air Force and Navy.
“The signing of the ACSA is a very welcome development,” Trinidad said at a news briefing at Camp Aguinaldo. “It is the first step. It’s the initial step in implementing the enhanced defense relationship between Japan and the Philippines.”
Trinidad said the Department of National Defense would issue further guidance on the agreement’s implementation.
“Without focusing on a particular capability, this ACSA will allow the extension of our operational reach,” he said. “This will strengthen the support and sustainment of our capabilities across the services.”
The agreement is also expected to complement the Philippine military’s modernization program as it shifts its focus from internal security to territorial and external defense.
The Philippines and Japan signed the ACSA on Jan. 15, 2026, establishing the legal framework for sharing logistical support between their armed forces.
The pact follows the Philippines-Japan Reciprocal Access Agreement, which took effect in September 2025. That agreement establishes rules governing the entry of Philippine and Japanese forces into each other’s territory for joint exercises, training and other cooperative activities.
