Will Adams, was wrecked in Japan, and on being interrogated naturally
gave a good British account of the authors of the Armada. As the
Japanese had by this time mastered the use and manufacture of fire-arms,
they began to think that they had nothing more to learn from Christian
nations.

Meanwhile, a succession of three great men--Nobunaga, Hideyoshi, and
Iyeyasu--had succeeded in unifying Japan, destroying the
quasi-independence of the feudal nobles, and establishing that reign of
internal peace which lasted until the Restoration--period of nearly two
and a half centuries. It was possible, therefore, for the Central
Government to enforce whatever policy it chose to adopt with regard to
the foreigners and their religion. The Jesuits and the Friars between
them had made a considerable number of converts in Japan, probably about
300,000. Most of these were in the island of Kyushu, the last region to
be subdued by Hideyoshi. They tended to disloyalty, not only on account
of their Christianity, but also on account of their geographical
position. It was in this region that the revolt against the Shogun began
in 1867, and Satsuma, the chief clan in the island of Kyushu, has had
great power in the Government ever since the Restoration, except during
its rebellion of 1877. It is hard to disentangle what belongs to
Christianity and what to mere hostility to the Central Government in the
movements of the sixteenth and seventeenth centuries. However that may
be, Iyeyasu decided to persecute the Christians vigorously, if possible
without losing the foreign trade. His successors were even more
anti-Christian and less anxious for trade. After an abortive revolt in
1637, Christianity was stamped out, and foreign trade was prohibited in
the most vigorous terms:--
