A Complete Timeline of Portuguese-Japanese Exchange, 1543–1650

Sometime in late September 1543, a Chinese junk belonging to the pirate-merchant Wang Zhi limped into Maenohama cove on the southern tip of Tanegashima, a slender island off the coast of Kyushu. The ship had been blown wildly off course by a typhoon. Its cargo was unremarkable. Its crew, numbering over a hundred, were mostly Chinese. But among them were men who looked like nothing the villagers had ever seen: tall, oddly dressed, with prominent noses and an inability to eat with chopsticks. They were Portuguese. And their accidental arrival would set in motion one of the most extraordinary episodes of cross-cultural exchange in early modern history.

What followed over the next century, a period the Japanese would come to call the Nanban era, after the “Southern Barbarians” who sailed up from the south, was a collision of civilisations so improbable, so laced with mutual incomprehension, commercial greed, religious fervour, and staggering violence, that it reads less like conventional history and more like an adventure novel.

This is the full story of that collision: from the first fumbling attempts at communication to the final, blood-soaked severing of relations a century later. It is a story of matchlock guns and Marian theology, of silk cargoes and crucifixions, of teenage diplomats crossing oceans and artificial islands built to cage the foreigners who had once been honoured guests.

Prologue

Setting the Stage: How Portugal Got to the Edge of the World

To understand how three Portuguese merchants ended up seasick on a beach in southern Japan, you first need to understand that Portugal had spent the better part of a century doing something no European power had ever attempted: building a seaborne empire stretching from the coast of Africa to the South China Sea. It was, by any measure, a breathtaking act of overreach for a kingdom of roughly a million people clinging to the western edge of the Iberian Peninsula.

The project had begun in earnest in 1497, when King Manuel I dispatched Vasco da Gama with four ships and a mandate to find a direct sea route to the spice markets of Asia. Da Gama’s motivation was elegantly simple: the global spice trade was controlled by Mamluk Egypt and the Republic of Venice, and Portugal wanted to cut out the middlemen. His men arrived at Calicut on the Malabar Coast the following year and, when asked what they sought, responded with what may be the most honestly mercenary diplomatic statement in history: “Christians and spices.”

The profits from that first voyage were astronomical, roughly sixty times the cost of the expedition. This got the Crown’s attention. Over the next two decades, Portugal constructed what historians call the Estado da Índia: not a territorial empire in the conventional sense, but a chain of fortified ports, naval bases, and trading posts strung across the Indian Ocean like a necklace of gunpowder and customs houses. Afonso de Albuquerque, a commander whose military brilliance was matched only by his capacity for ruthlessness, captured Goa in 1510 and the strategic chokepoint of Malacca in 1511. Goa became the capital of the entire eastern enterprise, “Golden Goa,” they called it, a metropolis dripping with tropical wealth and Catholic ceremony at the hinge of the monsoon routes.

Malacca was the key that unlocked the China trade. By 1513, the explorer Jorge Álvares had become the first European to reach China by sea. Portuguese ships were soon swarming the southern Chinese coast, buying silk and porcelain and attempting, with varying degrees of success, to talk their way into official trading relationships with the Ming Dynasty. Between 1555 and 1557, they secured a permanent settlement at Macao on the Pearl River estuary, a toehold that would become the vital staging ground for everything that followed in Japan.

The whole apparatus was held together by naval artillery and a protection racket called the cartaz system, under which all local shipping in the Indian Ocean was required to purchase Portuguese safe-conduct passes. It was a mafia operation dressed in the robes of a crusade. And it worked astonishingly well, right up until it didn’t.

Japan in Pieces

The country the Portuguese stumbled into was, by any contemporary European standard, a paradox: culturally refined, technologically sophisticated, and tearing itself to shreds. Japan in the early sixteenth century was deep in the Sengoku Jidai, the Warring States period, a protracted civil war in which the authority of the Ashikaga shogunate had evaporated and regional warlords called daimyō waged relentless campaigns for territory, alliances, and survival.

This political fragmentation would prove extraordinarily important for the Portuguese, because it meant there was no central authority to either welcome or reject them. Individual daimyō were free to deal with the foreigners as they pleased, and many were greatly pleased indeed, because the Portuguese brought two things that a Japanese warlord in the grip of a civil war craved above all else: Chinese silk (which had become almost impossible to obtain through legitimate channels) and firearms.

Phase I · 1543–1569

First Contact and the Gunpowder Bargain

The Guns of Tanegashima

Back on that windswept beach in 1543, the problem of communication was immediate and seemingly insurmountable. The Portuguese spoke no Japanese. The villagers spoke no Portuguese. Wang Zhi, the Chinese merchant-pirate whose junk had carried them there, solved the problem by picking up a stick and writing Chinese characters in the sand. The local lord, Tanegashima Tokitaka, could read them. Diplomacy conducted in wet sand by a pirate intermediary: it was an inauspicious beginning for a century of exchange, but it worked.

What riveted Lord Tokitaka’s attention was not the Europeans themselves but the matchlock arquebuses they carried. He purchased two on the spot for a sum that would have made a Lisbon arms dealer weep with joy, and immediately ordered his blacksmiths to copy them.

The speed of what followed was staggering. A merchant from Sakai and a warrior-monk from Negoro temple each learned the manufacturing process on Tanegashima and carried it back to central Japan. Within a decade, Japanese armorers were producing firearms in quantities that would eventually surpass anything in contemporary Europe. The guns were universally called tanegashima, after the island where they first appeared. A weapon introduced by accident in a remote backwater was about to reshape the entire military calculus of a civil war.

Francis Xavier and the Souls of Japan

The merchants were the first wave. The priests arrived six years later.

On 15 August 1549, the Jesuit Francis Xavier landed at Kagoshima in Satsuma province, accompanied by two Spanish Jesuits and three Japanese men, including a convert named Anjirō who had met Xavier in Malacca and served as his interpreter. Xavier was a Navarrese aristocrat with the zealotry of a man who had personally co-founded the Society of Jesus. His two years in Japan were a whirlwind of preaching, gift-giving, and occasional culture shock. He arrived convinced that the Japanese were the most rational people in Asia. He secured the patronage of the daimyō of Yamaguchi by presenting European curiosities, clocks, eyeglasses, wine, the kinds of diplomatic gifts that combined genuine wonder with a calculated appeal to vanity. He departed in November 1551, leaving Cosme de Torres in charge of the fledgling mission and a legacy that would transform, and ultimately convulse, Japanese society.

The Port Problem

For the first two decades of contact, the Portuguese were engaged in an awkward, often violent search for a safe harbour on the Kyushu coast. Each time they settled somewhere, things went wrong. At Hirado, where they traded between 1550 and 1561, overly enthusiastic Christian converts destroyed Buddhist temples, provoking riots. The local daimyō Matsuura Takanobu expelled the Jesuits.

So they moved to Yokoseura, where the daimyō Ōmura Sumitada offered them safe haven and tax exemptions. A Buddhist revolt destroyed the port within two years. They relocated to Fukuda. Matsuura Takanobu, evidently still furious, sent a naval fleet to attack them. The Portuguese beat it off in what is drily recorded as the Battle of Fukuda Bay in 1565.

Finally, in 1570, the Jesuits and Portuguese selected the deep-water bay of Nagasaki, an obscure fishing hamlet with excellent anchorage, minimal Buddhist infrastructure, and a local lord who was, by this point, an enthusiastic Christian. The first Portuguese ship entered Nagasaki harbour in 1571. The fishing village would never be the same.

The Price of Salvation

There was, from the very beginning, an intimate and deeply uncomfortable entanglement between Portuguese commerce and Jesuit evangelism. The Jesuits needed the trade to fund their mission. The daimyō needed Christianity, or at least the appearance of it, to attract the trade. The logic was circular and everyone understood it perfectly.

Ōmura Sumitada became Japan’s first Christian daimyō in 1563, baptised as Dom Bartolomeu. His conversion was sincere enough to produce spectacular collateral damage: he ordered the destruction of local shrines, forced mass baptisms upon tens of thousands of reluctant subjects, and eventually ceded the entire port of Nagasaki to the direct administrative control of the Society of Jesus in 1580. A Catholic religious order headquartered in Rome was now the municipal government of Japan’s most important international trading port. Other daimyō followed suit: Arima Yoshisada was baptised as Dom André in 1576; Ōtomo Yoshishige became Dom Francisco in 1578. The Portuguese referred to these allied lords as the “Christian daimyō,” and the Jesuits reported the conversions to Rome with breathless optimism.

Also arriving in 1563 was Luís Fróis, a Portuguese Jesuit chronicler whose decades of meticulous observation would produce some of the most detailed European accounts of sixteenth-century Japanese society, a priceless, if decidedly partisan, window into a vanishing world.

Phase II · 1570–1598

The Golden Age

The Black Ship and the Art of the Deal

The economic engine of the Nanban era was the Nau do Trato, the Great Ship of trade, known to the Japanese as the Kurofune, the “Black Ship.” Once a year, timed to the monsoon cycle, one of these massive carracks, sometimes weighing 1,600 tons, among the largest vessels afloat anywhere in the world, would lumber from Macao to Nagasaki bearing Chinese raw silk, and return groaning with Japanese silver.

The commerce was a royal monopoly. The right to command the annual Japan Voyage was granted by the Portuguese Crown or the Viceroy in Goa as a reward for distinguished service, or, increasingly, sold to the highest bidder. The Captain-Major of the voyage was part admiral, part colonial governor, and part venture capitalist: he collected a ten per cent freight charge on all goods carried aboard his ship. A single round trip could clear a personal fortune of 50,000 to 200,000 ducats. To put that in perspective, the annual salary of a Portuguese university professor at the time was about 80 ducats.

To prevent the kind of ruinous price competition that arose when dozens of individual merchants tried to undersell each other on the Nagasaki waterfront, the Portuguese and Japanese developed a regulated pricing mechanism called the pancada, literally “the strike.” A consortium of Japanese silk buyers would negotiate a single fixed price for the entire bulk cargo of raw silk before it was even unloaded. The Portuguese got their guaranteed margin. The Japanese consortium got exclusive wholesale access. Everyone made money, which was, in fairness, rather the point.

The Jesuits were cut in, too. They were allotted a quota of 50 to 100 piculs of white silk from each annual cargo, yielding a tidy annual income of 4,000 to 6,000 ducats, the financial backbone of the Japan mission. God’s work, it turned out, had excellent margins.

The Silver Engine

What made the whole system run was a quirk of global metallurgy: Japan was the second-largest silver producer in the world, responsible for up to a third of total global output, thanks to rich mines like Iwami and the island of Sado and the introduction of Korean cupellation techniques that made refining far more efficient.

“A Portuguese merchant could buy Chinese silk cheaply, sell it in Japan at a massive premium, take the silver back to Macao, and use it to buy even more silk. It was a money-printing machine.”

The Portuguese were exploiting an enormous arbitrage gap. In the late sixteenth century, the Portuguese were shipping around 20 metric tons of Japanese silver annually. By the early seventeenth century, that figure had ballooned to somewhere between 150 and 187 tons per year, a river of precious metal flowing from the mines of Japan to the markets of Canton and from there into the arteries of the global economy.

The Unifiers and Their Inconvenient Guests

While the silver flowed, Japan was transforming. In 1568, the warlord Oda Nobunaga rode into Kyoto and began hammering the fractured country back into something resembling a unified state. Nobunaga was delighted with the Jesuits, not, it must be said, because of any deep spiritual affinity, but because they were useful. They brought European technology, they provided intelligence about the wider world, and, most importantly, they represented an effective counterweight to the militant Buddhist sects that were making Nobunaga’s life extremely difficult. He granted the Jesuits permission to preach freely. He received the Jesuit Visitor Alessandro Valignano with something approaching warmth. It was a golden period for the mission.

Valignano, a tall, intellectually formidable Italian, used his inspection tour of 1579–1582 to overhaul the entire Japan mission, insisting on cultural adaptation and the training of a native Japanese clergy. It was Valignano who conceived perhaps the most audacious publicity stunt in Jesuit history: the Tenshō Embassy of 1582, in which four young Japanese Christian nobles were dispatched to Europe to visit the courts of Philip II of Spain and Pope Gregory XIII. Four teenagers from Kyushu, crossing oceans to kneel before the Pope. The diplomatic sensation it caused in both hemispheres was precisely the point.

But Nobunaga died in 1582, betrayed and killed by one of his own generals, and the man who seized his mantle was his brilliant, mercurial lieutenant Toyotomi Hideyoshi. Hideyoshi initially tolerated the Christians. Then he conquered Kyushu in 1587 and saw, with his own eyes, the extent of Jesuit influence: the forced conversions, the destroyed temples, the fact that a foreign religious order was administering the country’s premier international port. His reaction was swift. On 24 July 1587, Hideyoshi issued the Bateren Tsuihō Rei, an anti-missionary edict ordering the expulsion of all missionaries and confiscating Nagasaki from the Jesuits.

Then, in a characteristic demonstration of Hideyoshi’s ability to hold two contradictory positions simultaneously, he did almost nothing to enforce it. He still needed Portuguese trade. The Jesuits went underground, the ships kept coming, and the pancada continued to operate. An uneasy hypocrisy settled over Nagasaki.

When the Tenshō Embassy returned in 1590, they brought with them a moveable-type printing press, one of the few gifts from that era whose consequences would outlast the political upheavals that followed. Between 1592 and 1598, Hideyoshi launched two calamitous invasions of Korea. Among the ugly side-effects was a flood of Korean captives arriving at Nagasaki, where Portuguese merchants purchased many of them for export to Macao, India, and beyond, a grim traffic in human cargo that sat uneasily alongside the Jesuits’ stated mission of salvation.

The breaking point came with the San Felipe Incident of 1596. A Spanish galleon wrecked on the coast of Shikoku. Its pilot, reportedly attempting to impress the local authorities, boasted that Spain used missionaries as a fifth column to soften up countries for military conquest. Whether the pilot actually said this, or whether the story was amplified by Portuguese Jesuits eager to discredit their Spanish Franciscan rivals, the damage was done. Hideyoshi was furious. On 5 February 1597, twenty-six Christians — six Franciscan friars, three Japanese Jesuits, and seventeen Japanese laypeople — were crucified on a hill overlooking Nagasaki. It was a warning. But it was not yet the end.

Phase III · 1600–1639

The Tightening Noose

New Players, New Anxieties

Hideyoshi died in 1598, and the man who emerged from the ensuing power struggle was Tokugawa Ieyasu, patient, calculating, and profoundly suspicious. In April 1600, months before the battle of Sekigahara would cement his supremacy, a half-dead Dutch ship called the Liefde drifted ashore in Bungo province. Among the twenty-four surviving crew were the English pilot William Adams and the Dutch merchant Jan Joosten van Lodensteijn.

The Portuguese Jesuits, alarmed, urged Ieyasu to execute the newcomers as pirates. Ieyasu, characteristically, did the opposite. He had Adams brought to Osaka Castle and interrogated him at length. What Adams told him changed the calculus of Japanese foreign policy: Catholic nations, Adams explained, used missionaries to subvert local populations before military conquest. The Dutch and English, by contrast, were Protestants. They had no interest in conversion. They were, to use a term Ieyasu would have appreciated, purely transactional.

In 1609, the Dutch established a trading factory at Hirado. The English followed in 1613, though they would voluntarily pull out a decade later, unable to turn a profit. The importance of these arrivals was not primarily commercial — the Dutch volumes were initially modest — but strategic. For the first time, Japan had European trading partners who didn’t come bundled with priests.

The Edicts

The unwinding, once it began, was methodical. In 1612, a bribery scandal involving a Christian samurai retainer embarrassed the shogunate, and Ieyasu banned Christianity in Tokugawa domains. In 1614, he issued a definitive edict banning Christianity outright and ordering the expulsion of all missionaries. By this point, the Christian population was estimated at up to 300,000. Prominent Christian samurai, including the celebrated Takayama Ukon, were exiled. Portuguese merchants were allowed to remain, but the mission, officially, was over.

Unofficially, of course, missionaries continued to infiltrate Japan in disguise, and the crypto-Christian communities of Kyushu persisted in secret, maintaining their faith in hidden rooms with concealed icons. The Tokugawa response to this defiance grew steadily more savage. The persecutions of the 1620s were horrific in their inventiveness: Christians were suspended upside-down over pits, slowly bled, boiled in hot springs, or subjected to the water torture known as tsurushi. In 1622 alone, fifty-five Christians were executed in Nagasaki in a single mass burning and beheading.

Caging the Barbarians

Under the third shogun, Tokugawa Iemitsu, the screws tightened into a comprehensive system. Between 1633 and 1639, the bakufu issued a series of maritime edicts, the sakoku (“closed country”) orders, that systematically sealed Japan off from the outside world. In 1635, all Japanese were forbidden to travel overseas on pain of death. In 1636, the shogunate deported 287 Eurasian children, the mixed-race offspring of European fathers and Japanese mothers, to Macao, a policy of ethnic cleansing designed to sever the last remaining Catholic bloodlines. That same year, the Portuguese merchants still clinging to their Nagasaki operations were forcibly relocated to Dejima: a tiny, fan-shaped artificial island in Nagasaki harbour, built specifically to contain and surveil them. It was, in effect, an open-air prison with trading privileges.

Shimabara: The Breaking Point

The final catastrophe erupted in December 1637. In the Shimabara Peninsula and the Amakusa Islands, tens of thousands of peasants, crushed by punitive taxation, starving, and brutally persecuted for their faith, rose in revolt. Many were crypto-Christians. They rallied behind a charismatic teenage leader named Amakusa Shirō, raised crosses and Catholic banners, and fortified themselves inside the ruins of Hara Castle. The estimated number of rebels was 37,000.

The shogunate sent 100,000 troops. The siege dragged on for months. At one point, desperate to break the deadlock, the bakufu made a request that laid bare the true nature of European alliances in Japan: they asked the Dutch factory head, Nicolaes Couckebacker, to provide naval bombardment against the Christian rebels. The Dutch obliged, sending the warship De Ryp to shell Hara Castle. It was a decision of cold commercial pragmatism — the Dutch were proving to the shogunate, in the most emphatic terms possible, that Protestant Europeans would cheerfully bombard Catholic insurrectionists if it kept the trade flowing.

In April 1638, the castle fell. Virtually all 37,000 defenders were killed. The rebellion confirmed every fear the Tokugawa shogunate harboured about the intersection of Christianity and political subversion. The Portuguese, the bakufu was now convinced, had fomented the uprising and continued to smuggle priests into the country. The response, this time, would be final.

On 4 August 1639, the bakufu issued its last sakoku edict. All Portuguese ships were banned from Japan. Any vessel that dared approach would be destroyed, its crew beheaded. The century-long Portuguese-Japanese exchange was over.

Phase IV · 1639–1650

The Final Rupture

The Embassy They Should Not Have Sent

Macao could not accept the verdict. The city’s entire economy was built on Japanese silver. In 1640, desperate to reverse the ban, the Leal Senado of Macao dispatched an uninvited diplomatic mission led by Captain Luís País Pacheco with a delegation of seventy-four men. It was an act of extraordinary, suicidal optimism.

The Japanese response was absolute. Sixty-one members of the embassy were executed in Nagasaki. Thirteen low-ranking crewmen were spared, not out of mercy, but so they could carry the message back to Macao. The message was unambiguous: do not return.

The Inheritors

In 1641, the Dutch were ordered to relocate from their factory at Hirado to the now-vacant island of Dejima. They inherited the European monopoly on Japanese trade, and they inherited the cage. For the next two centuries, the Dutch East India Company men on Dejima would endure extraordinary restrictions: forbidden from learning Japanese, from bringing their families, from practising their faith openly. They were required to submit annual intelligence reports, the Oranda Fūsetsugaki, keeping the shogunate remarkably well-informed about global affairs.

Portugal made one last attempt. In June 1647, a royal embassy under Captain Gonçalo de Siqueira de Souza anchored off Nagasaki, hoping to negotiate the resumption of trade in copper and silver. The bakufu mobilised regional daimyō forces along the coast. After more than a month anchored in the bay, forbidden to disembark, the embassy was ordered to leave. It was the final word.

Epilogue

The Slow Transmission Through Dejima

The Dutch, confined to their miniature island, served, somewhat despite themselves, as Japan’s two-century window to the West. Through Dejima, European books, scientific instruments, and medical texts trickled into the country. In 1720, Shogun Tokugawa Yoshimune, a ruler of unusually restless curiosity, lifted the ban on importing non-Christian foreign books. This seemingly modest administrative decision unleashed Rangaku, “Dutch Learning”, a sustained Japanese engagement with European science, medicine, astronomy, and cartography. In 1774, a translated Dutch anatomy textbook, the Kaitai Shinsho, demonstrated to Japanese scholars that Western medicine had surpassed their own in certain critical respects. It was a revelation with long consequences.

Rangaku laid the intellectual groundwork for something nobody in 1639 could have predicted: when American warships arrived in Japanese waters in 1853, the “Black Ships” again, by coincidence or heavenly irony, Japan possessed a class of scholars who already understood enough Western science and technology to know what they were looking at. The Meiji Restoration that followed, and the extraordinary modernisation it produced, was built in part on foundations the Portuguese had inadvertently laid three centuries earlier.

Macao’s Twilight

For the Portuguese, the consequences of 1639 were devastating. Macao, which had grown fabulously wealthy as the middleman between Chinese silk and Japanese silver, was ruined almost overnight. The timing was savage: the expulsion from Japan was followed in 1640 by Portugal’s restoration of independence from Spain (which severed Macao’s profitable connection to Manila) and in 1641 by the Dutch capture of Malacca (which cut direct communications with Goa). Stripped of its three lifelines simultaneously, Macao collapsed from a global emporium to what one historian memorably described as a “suburb” — a drowsy backwater living on memories of a trade that no longer existed, owing 700,000 taels of silver to Japanese creditors who would never be repaid.
