context_page_description: Japanese–Portugal relations describes the foreign relations between Japan and Portugal. Although Portuguese sailors visited Japan first in 1543, diplomatic relations started in the nineteenth century.
context_section_description: The first affiliation between Portugal and Japan started in 1543, when the Portuguese discoveries,  the first Europeans to reach Japan, landed in the southern archipelago of Japan. This period of time is often entitled Nanban trade, where both Europeans and Asians would engage in mercantilism.
  The Portuguese at this time would find the port of Nagasaki, through the initiative of the Jesuit Gaspar Vilela and the Daimyo lord Ōmura Sumitada, in 1571.
  The expansion for commerce extended Portuguese influence in Japan, particularly in Kyushu, where the port became a strategic hot spot after the Portuguese assistance to Daimyo Sumitada on repelling an attack on the harbor by the Ryūzōji clan in 1578.
  The cargo of the first Portuguese ships upon docking in Japan were basically cargo coming from China (silk, porcelain, etc.). The Japanese craved these goods, which were prohibited from the contacts with the Chinese by the Emperor as punishment for the attacks of the Wokou piracy. Thus, the Portuguese acted as intermediaries in Asian trade.
  In 1592 the Portuguese trade with Japan started being increasingly challenged by Chinese smugglers on their reeds, in addition to Spanish vessels coming to Manila in 1600, the Dutch in 1609, and English in 1613.
  One of the many things that the Japanese were interested in were Portuguese guns.
  The first three Europeans to arrive in Japan in 1543 were Portuguese traders António Mota, Francisco Zeimoto and António Peixoto (also presumably Fernão Mendes Pinto).
  They arrived at the southern tip of Tanegashima, where they would introduce firearms to the local population. These muskets would later receive the name after its location.
  Because Japan was in the midst of a civil war, called the Sengoku period, the Japanese bought many Portuguese guns. Oda Nobunaga, a famous daimyo who nearly unified all of Japan, made extensive use of guns (arquebus) playing a key role in the Battle of Nagashino. Within a year, Japanese smiths were able to reproduce the mechanism and began to mass-produce the Portuguese arms. Later on, Tanegashima firearms were improved and Japanese matchlocks were of superior quality. As with Chinese experimentation with firearms of this period, the Japanese developed better sights and cord protection. And just 50 years later, his armies were equipped with a number of weapons perhaps greater than any contemporary army in Europe. The weapons were extremely important in the unification of Japan under Toyotomi Hideyoshi and Tokugawa Ieyasu, as well as in the invasion of Korea in 1592 and 1597. Europeans brought by trade not only weapons, but also soap, tobacco, and other unknown products in Feudal Japan.
  After the Portuguese first made contact with Japan in 1543, a large scale slave trade developed in which Portuguese purchased Japanese as slaves in Japan and sold them to various locations overseas, including Portugal itself, throughout the sixteenth and seventeenth centuries. 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 evangelization since the slave trade in Japanese was growing to massive proportions, so he commanded that it be banned in 1571
  Japanese slave women were even sold as concubines, serving on Portuguese ships and trading in Japan, mentioned by Luis Cerqueira, a Portuguese Jesuit, in a 1598 document. Japanese slaves were brought by the Portuguese to Macau, where some of them not only ended up being enslaved to Portuguese, but as slaves to other slaves, with the Portuguese owning Malay and African slaves, who in turn owned Japanese slaves of their own.
  Hideyoshi was so disgusted that his own Japanese people were being sold en masse into slavery on Kyushu, that he wrote a letter to Jesuit Vice-Provincial Gaspar Coelho on 24 July 1587 to
