Nanban trade
After the Portuguese first made contact with Japan in 1543, a large-scale slave trade developed in the Nanban trade, one of the Portuguese trade includes the Portuguese purchase of Japanese that sold them to various locations overseas, including Portugal itself, the Nanban trade existed from 1543 to 1614s. Many documents mention the large slave trade along with protests against the enslavement of Japanese. Japanese slaves are believed to be the first of their nation to end up in Europe, and the Portuguese purchased large numbers of Japanese slave girls to bring to Portugal for sexual purposes, as noted by the Church in 1555. King Sebastian feared that it was having a negative effect on Catholic proselytization since the slave trade in Japanese was growing to large proportions, so he commanded that it be banned in 1571. Records of three Japanese slaves dating from the 16th century, named Gaspar Fernandes, Miguel and Ventura who ended up in Mexico showed that they were purchased by Portuguese slave traders in Japan, brought to Manila from where they were shipped to Mexico by their owner Perez.
