Christianity’s precarious position in Japan

Christianity’s precarious position in Japan rests on a contradiction: the faith spreads quickly, especially in Kyushu, yet the security of its clergy, converts, and institutions depends on rulers whose policies can change abruptly. Protection is neither universal nor secure. It is negotiated through local authority, foreign trade, and political bargains—and Japanese converts can be more exposed than the foreign priests who preach to them.

Reversals under the Taikō

Rodrigues describes a history of alternating restriction and tolerance. In his account, the Taikō first ordered the priests to leave Japan and had them gathered at Nagasaki for deportation to Macao, with written instructions that they must not return on pain of death. The order was then left unenforced: the priests were allowed to remain, and many settled in Kyushu, where they were welcome. Rodrigues says the Taikō did not convert, closed few churches, and banished only two or three Christian daimyos, ostensibly to take their lands. The apparent return to ordinary conditions did not last. Rodrigues recounts that, three years before the conversation, the Taikō had twenty-six priests crucified at Nagasaki, then took no further action against the faith before his death.

The account comes from an injured, feverish Rodrigues, who is speaking haltingly and gives a compressed chronology, so it is best understood as his report rather than a neutral history. Even in that report, however, the central instability is plain: an expulsion order can be issued and abandoned, while a later burst of lethal persecution can occur without being followed by a sustained campaign. The change in policy offers no dependable assurance to those living under it.

Converts, suspicion, and local power

The danger is not confined to decisions made at court. In Anjiro, Yabu warns a priest to leave and stay away, implying that a future visit might be treated as evidence that Christian peasants or vassals were considering treason. The threat relies on a sharp imbalance: foreign priests are protected, but their Japanese converts are not. A Christian community can therefore be tolerated in principle while its local members remain vulnerable to a lord’s suspicions and punishments.

Kasigi Omi understands Christianity partly through the problem it presents to political control. Recalling what he learned from Jiro, a former apprentice priest, he identifies the Christian emphasis on mutual love and the sanctity of life as a weakness from the perspective of rulers accustomed to honor and duty. He reasons that a Christian leader might be controlled by threatening the life of one of his men. Omi recognizes that voicing this idea is dangerous, and his mother silently warns him; the discussion is shadowed by the torture death already associated with the danger of speaking. Christianity is thus not only a foreign doctrine in this setting. Its teachings are interpreted as potential leverage over believers, while suspicion of their loyalties makes them a possible target of coercion.

Growth and the limits of foreign authority

Despite this exposure, Rodrigues reports that the faith is growing rapidly. Since the Taikō’s death, he says, converts have increased and people who had been Christian in secret have begun attending church openly. He estimates that hundreds of thousands have converted, says most of Kyushu is Catholic, and describes most of its daimyos as converts. He calls Nagasaki a Catholic city and claims that the Jesuits own and run it and control its trade. He also reports a cathedral, a dozen churches, and many more across Kyushu, in contrast with only a few churches on Honshu. His figures and sweeping predictions are Rodrigues’s own claims, but they convey the scale of the political and religious presence he believes is taking shape.

That growth does not remove the constraints imposed by Japanese sovereignty. Toranaga tells John Blackthorne that foreigners are present only by permission and that public mischief or quarrels will be punished by death. When Blackthorne tries to turn an interrogation toward trade and repairs for his ship, Toranaga refuses to let him set the subject or terms of the discussion. The rule is presented as applying to foreigners generally, not just to Christians, but it makes clear that foreign religious and commercial activity has no independent right to operate outside the ruler’s authority.

The same limits shape conflict between European powers. Blackthorne describes his Dutch letters of marque as lawful authorization from the rulers of the Netherlands to wage war against their enemies and seek markets. Toranaga then asks whether the Netherlands, formerly under the Spanish king, is in rebellion against its lawful ruler. The exchange exposes how one action can carry opposing meanings: Blackthorne presents privateering as legitimate service, while his enemies can call it piracy and religious heresy. Toranaga treats these competing foreign claims as matters to question, not permissions to act freely in Japan.

Bargains, boundaries, and political use

Toranaga draws a firm line between warfare abroad and violence on Japanese soil. Mariko conveys his position that no daimyo would permit one foreign nation to attack another or kill Japanese people in Japan. A foreigner may harry an enemy at sea, but Toranaga will not authorize a land attack; he insists that Japan is the Land of the Gods and that Blackthorne must be patient. The boundary restrains foreign military action even as European religious and commercial rivalries press into Japanese politics.

Christian institutions can nevertheless become bargaining partners. Toranaga promises that, on the forty-first day, the Jesuits may lay the foundation stone for the largest Christian temple in the Empire. The promise is made in return for Father Alvito’s pledge to do what he can to persuade Lord Onoshi and Lord Kiyama to support Toranaga. When Alvito asks whether the land can be set aside immediately, Toranaga says it will be done once he arrives at Yedo. The temple is therefore both a significant concession and a political instrument: its authorization is tied to a specific date, location, and effort to win Christian daimyos as allies.

Across these episodes, Christian growth and Christian security move on separate tracks. The number of believers and the reach of the Jesuits may increase, but neither guarantees protection from a local lord, a future reversal by the central ruler, or restrictions on foreign action. The faith’s position is precarious precisely because its expanding institutions and communities are entangled with powers that can shelter, bargain with, or endanger them.
