In the autumn of 1543, a storm-blown Chinese junk carrying Portuguese merchants made landfall at Tanegashima, an island off southern Kyushu. The arquebuses they carried were copied within months, and word of the “southern barbarians” — nanban-jin — spread quickly through a Japan consumed by civil war. Six years later Francis Xavier stepped ashore at Kagoshima, opening the Jesuit mission that would entangle commerce and Christianity for the next century.
The trade itself rested on a peculiarity of East Asian politics: Ming China had banned direct trade with Japan, and the Portuguese, established at Macau from the 1550s, stepped in as middlemen — exchanging Chinese silk for Japanese silver at margins that funded both the Estado da Índia and the mission. The annual carrack became the greatest prize in Kyushu, and daimyō competed to host it, some accepting baptism in the bargain.
By the time Oda Nobunaga began his drive to unify Japan in 1568, the pattern of the century was set: a trade too profitable to refuse, carried by foreigners whose religion would prove increasingly difficult to accept.
