Christianity’s precarious standing under Japan’s expulsion edict

Christianity’s precarious standing under Japan’s expulsion edict is shaped by a contradiction: the faith is vulnerable to state coercion, yet the Church retains influence because it is entangled with trade and diplomacy. The Taikō’s edicts threaten clergy and converts with expulsion or death, and their continued official force leaves religious life dependent on discretion and political calculation. The Jesuits’ influence offers protection, but it also makes the Church a participant in the contests that endanger it.

Edicts and conditional survival

The danger becomes stark in Father Alvito’s recollection of the crisis that followed a seemingly favorable audience between the Taikō and Father Superior da Cunha. The meeting at sunset appeared almost like an act of contrition, and the Taikō seemed close to converting. In the middle of that night, however, the expulsion edicts ordered every religious order to leave Japan within twenty days on pain of death. Japanese converts were ordered to recant immediately or face exile or execution. The abrupt reversal makes clear that apparent favor offered no reliable security.

Da Cunha responded in desperation. He urged the Christian daimyos of Kyushu, including Onoshi and Kiyama, to rebel in order to save the Church, and he wrote for conquistadores to strengthen the revolt. His decision joined religious survival to armed political action, exposing the faith to further danger. Dell’Aqua later considered how panic, fear, pride, or arrogance could drive such a mistake, while also recognizing that da Cunha had been left to respond alone: a letter to Goa could take months each way, and he had written immediately after the disaster.

The edicts were not enforced as comprehensively as their wording threatened. After ten weeks, news reached dell’Aqua that the Church had not been obliterated and that the Taikō was no longer enforcing the new laws in full. About fifty churches had been burned, and Takayama had been crushed. The edicts nevertheless remained officially in force. The accommodation that followed required Fathers to be more discreet about conversions, converts to behave discreetly, and public worship and demonstrations to cease; the burning of Buddhist churches by Christian zealots was also forbidden. Survival therefore meant neither secure legal standing nor unrestricted worship: it depended on restraint under a threat that had not been formally withdrawn.

Trade, interpretation, and institutional vulnerability

The Church’s political position is inseparable from commerce. Dell’Aqua explains that the safety of the Church touches both politics and the silk trade. The Jesuits are sought out partly because they can speak Japanese and Portuguese and interpret or intercede in trade matters. Japanese daimyos, he says, believe that expelling the Jesuits and suppressing the faith would also prevent the Portuguese Black Ships from returning. He regards that belief as mistaken: Portuguese traders, in his assessment, would pursue their commercial interests regardless of the Church’s position.

That gap between the daimyos’ belief and the Jesuits’ understanding creates influence as well as risk. The Church can be treated as the indispensable link to trade, but its position rests on a political assumption about what Portuguese merchants will do. Dell’Aqua also resists the Portuguese Captain-General’s proposal to use Christian rulers and foreign soldiers to remove Toranaga. Japan, he argues, cannot be treated like territories conquered elsewhere, and he formally asks the Captain-General not to interfere in Japanese internal politics. A foreign intervention intended to defend Christianity could instead make the Church appear responsible for an attack on the country’s political order.

A concealed weapons shipment further exposes the institution’s vulnerability from within. After the edicts were issued, guns sent earlier under da Cunha’s seal remained in Jesuit warehouses at Nagasaki. They were eventually smuggled back to Macao under dell’Aqua’s seal. The shipment had already gone before the crisis, but its discovery could connect the Church to covert military activity. Dell’Aqua hopes the secret will remain buried, while fearing that secrets do not leave those who know them in peace. His anxiety is not simply about individual culpability: evidence of Jesuit arms dealing could undermine the discretion on which the Church’s continued presence depends.

Toranaga’s religious bargain

Toranaga makes this precarious position explicit when he presses Father Alvito to use his access to the Church’s leadership. He contrasts Ishido’s opposition to the religion and desire to enforce the Taikō’s expulsion edicts with his own desire to expand trade. Alvito replies that the Jesuits do not control the Christian daimyos, and Toranaga asks how, then, he might influence them. The exchange places the Jesuits between religious authority and political leverage: they can interpret, advise, and negotiate, but they cannot simply command their Japanese allies.

Toranaga’s proposed terms sharpen that tension. He envisages winning Onoshi and Kiyama, repealing the Taikō’s edicts within forty days, and barring other priests from Japan. The Jesuits would receive an exclusive position throughout the empire, while the other religious orders—the Black Robes—would be forbidden to come; Toranaga even offers their heads if the Jesuits want them. For Alvito, the offer is almost beyond price because exclusivity could protect the Church as it grows stronger. But the proposal’s promise of safety is inseparable from exclusion and from Toranaga’s attempt to defeat Ishido and dominate the Council. Religious security is being offered as an outcome of political victory, not as a neutral guarantee.

A standing contingent on power

The contrast between Ishido and Toranaga reveals that the Church has no independent guarantee of protection. Ishido is described as wanting the edicts enforced and the country closed to foreigners; Toranaga presents himself as favoring expanding trade and offers repeal, but demands a religious arrangement that serves his political design. Alvito is wary of speaking too freely or offending Toranaga, even as he recognizes how much the proposal could mean for the Church. The Jesuits’ access to power is real, but so is their exposure to the consequences of choosing, or appearing to choose, a side.

Christianity’s survival in Japan thus rests on unstable conditions: laws that remain in force despite partial relaxation, worship that must become less public, converts whose safety was explicitly threatened, and foreign commerce whose continuation is wrongly assumed to depend on Jesuit presence. The Church can bargain through its language and trade networks, yet those same connections invite political suspicion. Its precariousness lies not only in the possibility of renewed persecution, but in the fact that each apparent safeguard—discretion, mediation, or exclusive favor—can bind religious life more tightly to the shifting interests of rulers and merchants.
