Nagasaki is the capital and the largest city of Nagasaki Prefecture on the island of Kyushu in Japan. Nagasaki was founded by the Portuguese in the second half of the 16th century on the site of a small fishing village, formerly part of Nishisonogi District. It became a center of Portuguese and other European peoples’ influence in the 16th through 19th centuries, and the Churches and Christian Sites in Nagasaki have been proposed for inscription on the UNESCO World Heritage List. Part of Nagasaki was home to a major Imperial Japanese Navy base during the First Sino-Japanese War and Russo-Japanese War.
A small fishing village secluded by harbours, Nagasaki enjoyed little historical significance until contact with European explorers in 1543—among them, possibly, Fernão Mendes Pinto—when a Portuguese ship landed nearby in Tanegashima. Soon after, Portuguese ships started sailing to Japan as regular trade freighters, thus increasing the contact and trade relations between Japan and the rest of the world, and particularly with mainland China, with whom Japan had previously severed its commercial and political ties, mainly due to a number of incidents involving Wokou piracy in the South China Sea, with the Portuguese now serving as intermediaries between the two Asian countries. Despite the mutual advantages derived from these trading contacts, which would soon be acknowledged by all parts involved, the lack of a proper seaport in Kyūshū for the purpose of harboring foreign ships posed a major problem for both merchants and the Kyushu daimyo (feudal lords) who expected to collect great advantages from these trade intercourse with the Portuguese. In the meantime, Navarrese Jesuit missionary St. Francis Xavier arrived in Kagoshima, South Kyūshū, in 1549, and soon initiated a thorough campaign of evangelization throughout Japan, but left for China in 1551 and died soon afterwards. His followers who remained behind converted a number of daimyo. The most notable among them was Ōmura Sumitada, who derived great profit from his conversion to the „Kirishitan” religion through an accompanying deal to receive a portion of the trade from Portuguese ships. In 1569, Ōmura gave permit for the establishment of a port with the purpose of harboring Portuguese ships in Nagasaki, which was finally set in 1571, under the supervision of the Jesuit missionary Gaspar Vilela and Portuguese Captain-Major Tristão Vaz de Veiga, with Ōmura’s personal assistance.
In 1602, Augustinian missionaries also arrived in Japan, and when Tokugawa Ieyasu took power in 1603, Catholicism was still tolerated. Many Catholic daimyo had been critical allies at the Battle of Sekigahara, and the Tokugawa position was not strong enough to move against them. Once Osaka Castle had been taken and Toyotomi Hideyoshi’s offspring killed, though, the Tokugawa dominance was assured. In addition, the Dutch and English presence allowed trade without religious strings attached. Thus, in 1614, Catholicism was officially banned and all missionaries ordered to leave. Most Catholic daimyo apostatized, and forced their subjects to do so, although a few would not renounce the religion and left the country for Macau, Luzon and Japantowns in Southeast Asia. A brutal campaign of persecution followed, with thousands of converts across Kyūshū and other parts of Japan killed, tortured, or forced to renounce their religion.
Consensus among historians was once that Nagasaki was Japan’s only window on the world during its time as a closed country in the Tokugawa era. However, nowadays it is generally accepted that this was not the case, since Japan interacted and traded with the Ryūkyū Kingdom, Korea and Russia through Satsuma, Tsushima and Matsumae respectively. Nevertheless, Nagasaki was depicted in contemporary art and literature as a cosmopolitan port brimming with exotic curiosities from the Western World.
