The 1614 Expulsion Edict: The Monk, the Manifesto, and the End of Christian Japan

Chapter One

The Assignment

On the last day of January 1614, Tokugawa Ieyasu summoned a Zen monk to Edo Castle and told him to write the end of Christianity in Japan.

The monk’s name was Konchiin Sūden. He was 65 years old, the abbot of Nanzenji, one of Kyoto’s Five Great Zen Temples, and, for the past six years, the closest thing the Tokugawa shogunate had to a minister of ideology. He was also a former warrior who had taken three heads in battle at Mikata-ga-hara, which gives some indication of the kind of man Ieyasu liked to have around for drafting policy documents.

Sūden worked through the night. By the following morning, February 1, the document was ready. It was issued under the vermilion seal of the reigning shogun, Tokugawa Hidetada, Ieyasu’s son and political front man, and distributed to every province in Japan. Its official title was the Bateren Tsuihō no Fumi, the “Statement on the Expulsion of the Padres”. Its practical effect was to criminalise an entire religion, expel every foreign missionary from the archipelago, and compel 300,000 Japanese converts to choose between their faith and their lives.

Chapter Two

The Monk Who Killed Three Men

Konchiin Sūden’s biography reads like a character from a Kurosawa film who wandered into the wrong genre.

Born to a samurai family, he entered the Zen monastic tradition as a young man, but not before demonstrating that he understood the secular world perfectly well. At the Battle of Mikata-ga-hara in 1573, fighting in the service of Tokugawa Ieyasu against the forces of Takeda Shingen, the young warrior distinguished himself by taking three enemy heads in combat. This was not a footnote. In the economy of honour that governed samurai life, head-taking was the definitive measure of battlefield performance, the difference between a man who talked about war and a man who had done the work. Ieyasu rewarded him with a temple and the use of a three-star crest, gifts that marked Sūden as a man the future shogun intended to remember.

He entered the priesthood, rose through the Rinzai Zen hierarchy with the efficiency of someone who understood institutional politics as well as he understood meditation, and by the turn of the century had become abbot of Nanzenji, the apex of the Gozan system that governed Zen Buddhism’s relationship with the state. In 1608, Ieyasu, now the retired shogun, still the most powerful man in Japan, summoned Sūden to his residence at Sunpu Castle and installed him as a permanent political advisor.

The appointment made Sūden one of the three clerics who shaped early Tokugawa policy, alongside the Tendai monk Tenkai and the Yoshida Shinto priest Bonshun. Of the three, Sūden was the most politically active and the most ideologically aggressive. Where Tenkai focused on the deification of Ieyasu’s legacy and Bonshun on the proper performance of state ritual, Sūden took on the work that required a sharp pen and a sharper argument: foreign diplomacy, the regulation of religious institutions, and the intellectual case for destroying Christianity.

He built a temple called Konchiin at Shizuoka, then replicated it at Nanzenji in Kyoto and beside Zōjōji in Edo, a triple foundation that mirrored the shogunate’s own geographic power centres and ensured that Sūden always had a base within walking distance of whoever was making decisions. By 1612, he was formally placed in charge of Buddhist and Shinto institutional affairs, sharing oversight with Itakura Katsushige, the shogunate’s deputy in Kyoto. He was also the last holder of the soroku office, which gave him authority over the entire Zen monastic network.

In a government that officially separated the spiritual and secular spheres, Sūden occupied both.

Chapter Three

The Pretext and the Preparation

The standard narrative of the 1614 edict begins with the Okamoto Daihachi scandal of 1612, the bribery and forgery affair involving two prominent Christians that gave Ieyasu the domestic pretext to move against the Church. That story is told in full elsewhere in this series, and there is no need to rehearse its details here. What matters for understanding the edict is that the scandal provided the opportunity, not the cause.

Ieyasu had been preparing for this moment for years. The evidence is in Sūden’s own correspondence. As early as 1612, the monk had drafted a letter to the Spanish authorities in Manila whose central thesis, that Japan’s cosmological and social order was fundamentally incompatible with Christianity, would serve as the direct foundation for the 1614 decree. The letter to Manila was not a reaction to the Okamoto affair. It was a working draft of an ideology that had been under construction since at least 1608, when Sūden first entered the shogunate’s inner circle.

The intellectual inputs were various. William Adams, the English pilot who had become Ieyasu’s trusted advisor on European affairs, had been warning for years that Catholic missionaries operated as a vanguard for Iberian military conquest. The Dutch and English merchants at Hirado reinforced the message from a Protestant commercial perspective: they could offer the same trade goods without the subversive priests. The Spanish Philippines, where missionary activity and colonial administration worked hand in glove, provided a living case study of what happened when the padres got what they wanted.

The Neo-Confucian scholar Hayashi Razan, another of Ieyasu’s intellectual advisors, contributed the philosophical framework. Razan’s brand of Confucianism emphasised hierarchical social order, filial piety, and loyalty to the ruler as the natural laws of the universe, principles that Christianity, with its insistence on the primacy of divine over secular authority, directly contradicted. Between Sūden’s Buddhist nativism, Razan’s Confucian rationalism, and Adams’s intelligence briefings on European power politics, the shogunate had assembled a comprehensive intellectual case against the foreign religion long before the Okamoto scandal gave them the political cover to deploy it.

The scandal simply moved the timeline forward. In 1612, Ieyasu issued localised bans on Christianity within the shogunal domains, Sunpu, Edo, Kyoto, and Nagasaki. Churches were demolished. Fourteen Christian retainers were purged from Ieyasu’s own household at Sunpu, stripped of their rank and stipends. A Korean Christian woman named Julia Ota, one of Ieyasu’s favoured attendants, was exiled. The localised measures were severe but contained. They were also, as events would show, a rehearsal.

Chapter Four

The Document

The Bateren Tsuihō no Fumi was not a simple administrative order. It was a manifesto, a comprehensive statement of political theology that drew on Shinto, Buddhist, and Confucian thought to construct an argument for why Christianity was incompatible not merely with Japanese law but with the fundamental structure of the universe.

The document opened with cosmology. Japan, it declared, was the “Land of the Gods”, shinkoku. The principles of Yin and Yang, the positive and negative forces that generated all life and sustained all social order, were the absolute foundation of existence. This was not metaphor. For Sūden and the intellectual tradition he represented, cosmological order and political order were the same thing. The emperor ruled because the gods had ordained it. The shogun governed because the cosmic hierarchy demanded a temporal authority to maintain harmony between heaven and earth. The social order, lord over vassal, parent over child, husband over wife, was not a human invention. It was a reflection of the structure of reality itself.

Christianity, the edict argued, attacked this structure at its root. The foreign priests, the bateren, had come to Japan “not merely to exchange commodities, but with the sinister ambition to overthrow true doctrine, change the government, and obtain possession of the land”. Their converts were encouraged to “contravene governmental regulations, traduce Shinto native deities, calumniate the True Law of Buddhism, destroy righteousness, and corrupt goodness”. Christianity was not a competing faith. It was a “pernicious doctrine”, an “evil law”, jahō, and its continued existence on Japanese soil was “the germ of great disaster”.

The blending of traditions was deliberate and sophisticated. By grounding the anti-Christian argument simultaneously in Shinto nativism (Japan as the land of the gods), Buddhist orthodoxy (Christianity as a corruption of the True Law), and Confucian political theory (the foreign religion as an assault on the hierarchical social order), Sūden ensured that the edict spoke to every major intellectual tradition in Japan. A Shinto priest could read it and see the defence of the native deities. A Buddhist abbot could read it and see the protection of the dharma. A Confucian administrator could read it and see the preservation of social harmony. No one who mattered was left without a reason to agree.

Chapter Five

The Mandates

The ideological preamble established the why. The operative clauses established the what.

All foreign missionaries were ordered to leave Japan immediately, as soon as shipping could be arranged. There were no exceptions, no categories of tolerated clergy, no loopholes for men who had been in the country for decades and spoke better Japanese than some of their parishioners. The padres were to go, all of them, and they were to go now.

For Japanese converts, the decree was equally absolute but more personally devastating. Every Christian was required to formally renounce the foreign faith and register as a member of a recognised Buddhist sect. This was not a suggestion. It was a legal requirement backed by the full coercive power of the state. Failure to comply, failure to stand before a Buddhist priest, formally abjure Christianity, and accept registration in a temple’s parish rolls, was a crime.

The edict was to be disseminated throughout every province so that everyone, “down to the lowest classes”, would understand its terms. Regional daimyō were expected to enforce it within their domains. The era of quiet toleration, of looking the other way while Jesuits in Japanese clothing ministered to their secret flocks, the comfortable fiction that had sustained the mission since Hideyoshi’s largely unenforced edict of 1587, was finished.

Chapter Six

The Deportation

Instructions, of course, are one thing. Execution is another, and in early modern Japan, where communications moved at the speed of a horse and central authority diminished with every mile of mountain road, the gap between a decree issued in Edo and its enforcement in a Kyūshū fishing village could be measured in months.

In the major cities, however, the regime moved with startling efficiency. In the Kyoto area, enforcement began by mid-February 1614, within days of the edict’s promulgation. Churches were demolished. Christians were subjected to public humiliation designed to break their social standing and pressure them into apostasy. The regime understood that in a shame-based social order, public degradation could be as effective as physical punishment.

The foreign missionaries were rounded up and concentrated in Nagasaki, the city that had been the heart of the Christian enterprise since the Jesuits first established it as their base in the 1570s. There, in rudimentary internment camps, they waited for the ships that would carry them into exile.

The visible Society of Jesus in Japan effectively came to an end in November 1614, when the deportees were loaded onto vessels bound for foreign ports. The numbers tell the story of a community being dismantled. Around 65 priests, friars, and brothers sailed on three vessels to the Portuguese enclave of Macau. Another 23 took a ship to the Spanish colony of Manila. 88 Jesuits and 50 native catechists, the dōjuku, Japanese assistants who had served as the mission’s essential intermediaries, were divided between the two destinations, with roughly two-thirds heading for Macau on the annual silk carrack and the remainder bound for the Philippines. Approximately 300 Japanese lay Christians accompanied them into exile.

The total, around 148 clergy and religious, plus the lay deportees, represented the institutional skeleton of a mission that had, at its peak, claimed over 300,000 converts, operated hundreds of churches and seminaries, and wielded political influence that reached into the courts of the most powerful daimyō in the country. 70 years of work, packed onto a handful of ships and sent to Macau.

Chapter Seven

The Men Who Stayed

The deportation was not complete. The Tokugawa regime, for all its efficiency, was working at the limits of 17th century logistics, and roughly 47 missionaries, 27 Jesuits, plus Franciscans, Dominicans, and Augustinians, refused to board the ships. They went underground.

These men traded their cassocks for the clothing of Japanese commoners or disguised themselves as Spanish or Portuguese merchants. They slipped out of Nagasaki into the countryside, sheltered by networks of Japanese Christians who risked annihilation to hide them. The decision to remain was not taken lightly. The missionaries knew exactly what would happen if they were caught, because the regime had made the consequences explicit: anyone found harbouring a priest would be executed, along with their entire family and several neighbouring households.

For the next two decades, these hidden priests moved through rural Japan in a shadow existence. A dark mirror of the quiet ministry the Jesuits had conducted after Hideyoshi’s 1587 edict. They celebrated Mass in farmhouses, heard confessions in storerooms, baptised children in the dark. One by one, over the years that followed, the shogunate’s intelligence apparatus found them. Some were killed, many subjected to tortures specifically designed to break rather than destroy, apostatised. The most famous of these was Cristóvão Ferreira, the Jesuit provincial, the highest-ranking Catholic cleric in Japan, who broke under the ana-tsurushi pit torture in 1633, renounced his faith, and spent the rest of his life helping the shogunate dismantle the Church he had served for three decades.

Chapter Eight

The Machine

The 1614 edict created the legal framework. What followed was the construction of an enforcement apparatus so comprehensive, so bureaucratically sophisticated, and so psychologically acute that it successfully eradicated an entire religion from a country of 15 million people, and kept it eradicated for over two and a half centuries.

The centrepiece was the terauke seido, the temple registration system. Every household in Japan was required to register as parishioners of a specific Buddhist temple. The local priest, now functioning as an agent of the state as much as a minister of religion, was required to issue an annual certificate confirming that the family members were orthodox Buddhists free of any Christian taint. These certificates were compiled into population registers that gave the shogunate an unprecedented instrument of social surveillance: a comprehensive, annually updated census of the religious affiliation of every person in the country.

The system was elegant in its coercive simplicity. Without a temple certificate, a person could not marry, could not travel, could not conduct legal business, could not exist as a recognised member of society. The Buddhist clergy, in exchange for their cooperation, received guaranteed parishioners, a captive spiritual market, and the administrative power that came with being the state’s local enforcers of religious orthodoxy. It was a bargain that served both parties, at the expense of anyone who happened to believe in the wrong God.

The fumi-e, the trampling test, added a ritual dimension to the bureaucratic machinery. Suspected Christians were required to tread on sacred images of Christ or the Virgin Mary, typically cast as bronze plaques. The test was annual, compulsory in the areas of heaviest Christian concentration, and devastatingly effective. Refusal to step on the image identified the person as a believer and condemned them to torture or death. Compliance constituted a public act of apostasy, and those who complied were required to sign a written oath, the korobi shōmon, swearing by both the Christian God and the native Japanese deities that they had abandoned the “evil religion” and would accept divine retribution if they relapsed.

The regime completed the system with informants and collective punishment. Public notice boards throughout the country advertised cash bounties: five hundred silver pieces for denouncing a priest, three hundred for a lay brother or a relapsed apostate, one hundred for an ordinary believer or anyone providing them shelter. The goningumi, the five-family neighbourhood associations, ensured that the cost of concealment was distributed across entire communities. If a single Christian was discovered within a household, the entire five-family unit faced severe punishment or death. Every neighbour became a potential informer. Every closed door became a potential trap.

The torture, when it came, was designed with a specific purpose. The early persecutions had produced martyrs, men and women who died singing hymns while crowds of thirty thousand gathered to collect their remains as holy relics. The regime learned from the experience. Martyrs inspired. Apostates demoralised. The goal shifted from killing Christians to breaking them.

The methods were accordingly calibrated. Captives were boiled in the sulphurous hot springs of Mount Unzen. They were suspended upside down over pits of excrement in the ana-tsurushi, with small incisions on their foreheads to prevent them from losing consciousness too quickly from the blood pooling in their heads. The torture could last days. It was designed to be unbearable, and it was: even several foreign priests who had come to Japan specifically prepared for martyrdom, men who had rehearsed their deaths in the spiritual exercises of the Jesuits, who had steeled themselves against fire and sword, broke under the pit torture and recanted.
