For nearly a century Japan, with approximately 500,000 Catholics by the early 1600s, was the most spectacular success story in Asia for European missionaries. Why did so many convert? Some undoubtedly were attracted by the Christian message of salvation, but others hoped to gain economic or political advantage. The daimyo of Omura seems to have converted in the hope of attracting more trade to his port city of Nagasaki, and Oda Nobunaga (1534-1582) the general who unified approximately half of Japan, encouraged Christian missionaries to undermine the political influence of the powerful and wealthy Buddhist monasteries. Nobunaga’s tolerance of missionary activity was the main reason for the many converts in the region around Kyoto, Japan’s imperial city.
Although the dynamics of Japanese politics at first favored the European missionary effort, when those dynamics changed, Christianity was persecuted and finally crushed. Nobunaga’s successor, Hideyoshi (15 36-1598), launched the antiforeign, anti-Christian policy that culminated in the Tokugawa exclusion edicts. Hideyoshi distrusted Europeans’ motives after the Spaniards conquered the Philippines and came to question the loyalty of certain dalmyo who had converted. In 1597 he ordered the execution by crucifixion of nine Catholic missionaries and seventeen Japanese converts. In their singleminded pursuit of stability and order, the early Tokugawa also feared the subversive potential of Christianity and quickly moved to obliterate it, even at the expense of isolating Japan and ending a century of promising commercial contacts with China, Southeast Asia, and Europe.
Japan’s isolation policy was fully implemented by Tokugawa Iemitsu, the grandson of Ievasu and shogun from 1623 to 1641. He issued edicts that essentially closed Japan to all foreigners and prevented Japanese from leaving. The first of the following two documents, the most famous of Iemitsu’s edicts, is directed to the two commissioners of Nagasaki, a port city in southern Japan and a center of Christianity; the second deals with the continuing missionary efforts of Portuguese Jesuits, who refused to abandon their activities despite the regime’s persecution.
