Lots of information on how Holy Week is celebrated in the Philippines in this LiveJournal post:

In Spanish times, as part of the process for coopting the leading native families, among the distinctions the Spanish clergy would hand out to the local oligarchy would be the custodianship over certain religious images. Spanish style Catholicism is particularly obsessed with images and this obsession has merged quite well with prehispanic idolatry on the part of the people the Spanish happened to subjugate -in Mexico and the Philippines, for example, the images that have the greatest following, or devotions, are often dark-skinned, because the faithful could identify with them more; which is why, for example, when the Philippine Revolution against Spain took place, images with fair skin (say, painted to look white, or made of ivory) often had their noses cut off out of racial spite, but black madonnas and images of Christ were spared.

The images Filipinos are particularly devoted to are of Mary, so the country is replete with madonnas that are patronesses of everything from safe journeys (Nuestra Senora de Buen Viaje, in Antipolo), the rosary (Nuestra Senora dela Paz y la Santissimo Rosario originally in Manila and now in Quezon City -commonly known as Nuestra Senora de la Naval, as the defeat of many Dutch and British naval attacks against Spanish galleons traveling between Acapulco and Manila were attributed to her intercession), Our Lady of Perpetual Help (a more modern devotion introduced shortly before WW2, she is the patroness of the poor, of the scorned and those with hopeless causes -the devotion to her by the working classes and prostitutes is particularly intense), and so on. There is a national devotion to the Infant Jesus, called the Santo Nino (The Infant Jesus of Prague), dating back to Magellan leaving an image of the Sto. Nino in the Visayas which was “miraculously” rediscovered when the Spaniards returned; the Sto. Nino is the particular devotion of businessmen and merchants and anyone wanting prosperity and good luck, so it is rare not to find an office or a factory or any business establishment without a little Santo Nino image on display.
