In the sixteenth century Pangasinan was called the "Port of Japan" by the Spanish. The locals wore native apparel typical of other maritime Southeast Asian ethnic groups in addition to Japanese and Chinese silks. Even common people were clad in Chinese and Japanese cotton garments. They also blackened their teeth and were disgusted by the white teeth of foreigners, which were likened to that of animals. Also, used porcelain jars typical of Japanese and Chinese households. Japanese-style gunpowder weapons were also encountered in naval battles in the area. In exchange for these goods, traders from all over Asia would come to trade primarily for gold and slaves, but also for deerskins, civet and other local products. Other than a notably more extensive trade network with Japan and China, they were culturally similar to other Luzon groups to the south.
