Aquino, in a letter to Japanese Prime Minister Naoto Kan, expressed condolences to the victims in Japan.

"The Government of the Republic of the Philippines and the entire Filipino nation join me in expressing both our most profound condolences and sympathies, as well as our solidarity with Your Excellency and the people of Japan, as you strive to cope with this tragedy whose devastation, it pains us, are still unfolding," he said.

As a close friend and neighbor, Japan has constantly stood by the Philippines, as we dealt with past tribulations wrought by nature, Aquino said.

"During this difficult time, I assure Your Excellency that the Philippine Government stands ready, to extend any support and assistance within its capability, as Japan strives to cope with the aftermath of this tragic event," he added.

Aquino noted that Japan is also home to a vast number of Filipinos, whose welfare also represents a paramount concern.
