The ambassador of the Philippines to Japan (; ) is the Republic of the Philippines' foremost diplomatic representative in the State of Japan. As officer of the Philippine Department of Foreign Affairs, the head of the embassy, and the head of the Philippines' diplomatic mission there, the ambassador is the official representative of the president and the government of the Philippines to the emperor and government of Japan. The position has the rank and status of an ambassador extraordinary and plenipotentiary.
The ambassador is based at the embassy at 5 Chome-15-5, Roppongi, Minato City, Tokyo, Japan, and resides in The Kudan, located in 1-1-1 Fujimi, Chiyoda-ku, Tokyo, Japan.
The position is currently held by Mylene Garcia-Albano, who has been in office since 12 August 2022.
The diplomatic relations between the two countries were established on 14 October 1943, following the inauguration of the Second Republic under the administration of President Jose P. Laurel and amid the Second World War. Jorge B. Vargas, who had previously served as President Manuel L. Quezon's Secretary of National Defense and Executive Secretary, was appointed ambassador to the Empire of Japan after he declined to assume the Presidency under the Japanese occupation.
Following the defeat of Japan on 2 September 1945, relations were suspended and the post of the Philippine ambassador to the Japanese mainland became dormant until 1952 since the relations and credentials were redirected to the Supreme Commander for the Allied Powers in occupied Japan. In October 1952, the Japanese embassy in Manila was reestablished, according to the Treaty of San Francisco that was signed on 8 September 1951, which would serve as a formal conclusion of the Second World War. On 23 July 1956, right after the ratification of the Peace Treaty and Reparations Agreement between the Philippines and Japan (signed on 9 May 1956), the diplomatic relations between the two countries were fully reinstated, and the post of the Philippine ambassador to the Japanese mainland was re-established.
