Tanegashima, 1543: First Contact and the Gun that Changed Japan

"These men are traders from among the southwestern barbarians. They understand to a certain degree the distinction between Superior and Inferior, but I do not know whether they have a proper system of etiquette. They eat with their fingers instead of with chopsticks such as we use. They show their feelings without any self control. They cannot understand the meaning of written characters. They are people who spend their lives moving from place to place. They have no fixed abode and barter things which they have for those they do not, but overall they are a harmless sort of people."

Teppōki (Chronicle of the Musket), 1606

Part One

The Storm That Changed Everything

A Desperate Sea

It was the typhoon season of 1543, and somewhere in the waters between the Kingdom of Siam and the coast of China, a large Chinese junk was fighting for its life.

The ship had perhaps a hundred souls aboard. Chinese merchants, sailors, a handful of Malay crew, and tucked somewhere among them, conspicuous and strange, two Portuguese men who had little business being there. Their names were António da Mota and Francisco Zeimoto, and the circumstances that had placed them on this particular vessel, in this particular storm, were a tangle of desertion, opportunism, and bad luck that was entirely typical of the Portuguese adventurers who prowled the edges of Asia in those feverish years of exploration.

The junk was captained and likely owned by a remarkable man named Wang Zhi, known to the Japanese who would later encounter him as Wufeng, or Gohō. Wang Zhi was one of those figures who defied easy categorization. He was a merchant and a pirate, a Confucian scholar and a smuggler, a man who operated in the grey economy of the Ming Dynasty's unofficial maritime world. Officially, the Ming court forbade private sea trade, a prohibition which had the predictable effect of creating a thriving criminal class of merchant-pirates who did it anyway. Wang Zhi was among the most successful of these men. He commanded fleets, ran networks of informants, and navigated the delicate politics of Japanese, Chinese, and Portuguese commercial ambition of someone who understood that the only law that mattered was profit.

The Portuguese had almost certainly come aboard in Siam, in the great trading city of Ayutthaya, the historic capital of Siam from 1350 until 1767, 80 km north of modern day Bangkok. Ayutthaya sat at the center of Southeast Asian commerce like a spider in its web. The most reliable account, from the 16th-century Portuguese chronicler António Galvão, says that Mota and Zeimoto had been serving under Portuguese captain Diogo de Freitas, and that for reasons which history has not recorded, a quarrel, a debt, a moment of sheer recklessness, they had fled their commander's authority and thrown in their lot with Wang Zhi's Chinese crew. Another chronicler, Diogo do Couto, suggests they were simply private traders who had loaded the junk with hides and goods, hoping to sell them in China, where the returns were extraordinary.

Whatever the precise circumstances, they were at sea when the typhoon found them.

Forty Days of Darkness

A typhoon in those waters is not a storm in any ordinary sense. It is a system of atmospheric violence so vast and so sustained that it does not simply toss a ship about; it displaces it from the world. Ships that entered typhoons emerged, if they emerged at all, in waters they did not recognize, their navigation stars gone, their compasses unreliable, their supplies damaged, their crews broken.

The junk was blown east. For days, then weeks, the wind and current carried her away from any coast she knew, out into the open Pacific, into waters that her Chinese and Malay crew had never navigated. Somewhere in this chaos, if the Portuguese chronicler Galvão is correct, one of the three original Portuguese passengers, a man named António Peixoto, was lost. Whether he was swept overboard by a wave, taken by illness, or simply vanished is unknown. He does not appear in the Japanese accounts of what came next.

The two survivors, Mota and Zeimoto, clung to the heaving deck of a vessel that no longer knew where it was.

And then, one morning in late September 1543, the 25th day of the 8th month by the Japanese lunar calendar, which corresponds to approximately September 23rd in the Western reckoning, the lookout would have seen land. Low and green on the horizon, impossibly welcome. The junk made for it. They came to anchor in a cove called Maenohama, near the village of Nishimura, on the southeastern tip of a small island.

They had arrived on Tanegashima.

Part Two

The Island at the Edge of the World

A Kingdom in Miniature

To understand what happened on Tanegashima in 1543, you first have to understand the island itself, not as it is today, a footnote in tourist brochures famous for its space center, but as it was then: a tightly wound, self-contained world of clan loyalties, ancient grudges, and samurai pride.

Tanegashima is a narrow sliver of land, 57 kilometres long and rarely more than ten kilometres wide, lying about 43 kilometres south of the main island of Kyushu. It is flat by the standards of its volcanic neighbors, its highest point barely clears 280 metres above sea level, which gives it an unusual openness, a landscape of rice paddies and pine-fringed coastlines that feels almost Mediterranean. Its climate is subtropical: hot, humid summers, mild winters, and rainfall so heavy that the island's agricultural character has always been defined by its abundance.

The island had been ruled for generations by the Tanegashima clan, a samurai family that had grown from a branch of the Higo clan during the turmoil that followed the collapse of the Hōjō shogunate in the 14th century. For two centuries, they had maintained a remarkable degree of autonomy, operating as minor lords in a feudal hierarchy that nominally placed them under the authority of the great Shimazu clan of Satsuma. In practice, Tanegashima felt its distance from the mainland keenly. It was close enough to matter, far enough to be left mostly to its own devices.

In the Muromachi period, Tanegashima had developed an important economic role: it served as a relay station on one of the main routes connecting the wealthy Japanese port city of Sakai to the Chinese city of Ningbo. The clan had cultivated careful relationships with the powerful Hosokawa family, one of two great powers who controlled the lucrative Chinese trade, and maintained a firm connection with the Honnō-ji Temple in Kyoto. These relationships made Tanegashima a known quantity in the world of maritime commerce, a place where ships came and went and strangers were, if not exactly welcomed, at least accommodated.

But in 1543, the island was also caught up in the brutal disorder of the Sengoku period, the era of the Warring States, when Japan's feudal fabric had been shredding for decades. Earlier that year, a revolt had broken out against the island's ruling lord, Tanegashima Shigetoki, described in the chronicles as a man of high-handed rule who had alienated both his subjects and his neighbors. Facing an invasion from the mainland by the Nejime clan, Shigetoki had been forced to flee across the narrow strait to the neighboring island of Yakushima. In a crisis born of necessity, he had handed over the lordship, and the defense of the castle, to his fifteen-year-old son, Naotoki, who took on the adult name of Tokitaka. Shigetoki calculated that the grievance of the revolt was with himself, and handing over power to his son would keep the family in power.

By the time the Chinese junk came to anchor in the cove of Maenohama, the situation had stabilized enough for Shigetoki to return. But the young Tokitaka remained the nominal head of the clan. He was, by every account that survives, an extraordinary young man: intellectually curious, politically astute well beyond his years, and possessed of a quality that would define the events to come, an almost reckless openness to the new.

The Man in the Sand

When the great junk dropped anchor in the cove, the first Japanese person to approach it was not a lord or a warrior. He was the local headman of the village of Nishimura, a samurai retainer of modest rank named Nishimura Oribenojō. He came to the beach as any responsible village official would, to assess the situation.

What he found was extraordinary. The ship was enormous, a large ocean-going junk of the kind that plied the Chinese coastal trade, but battered by weeks at sea. And among its passengers were two men who looked like nothing anyone on Tanegashima had ever seen. Their skin was different, their clothes were different, their faces were different. They stood on the deck of the Chinese vessel with the slightly dazed look of men who had survived something terrible and had not yet fully processed the fact that they were alive.

The problem was immediate and practical. No one could understand anyone else. The Chinese crew spoke Cantonese and Mandarin. The Portuguese spoke Portuguese and probably some Malay. The Japanese spoke Japanese. The linguistic gulf seemed absolute.

It was not. Because Nishimura was an educated man, he could read and write Chinese characters, where each symbol directly represents a specific concept, object, or unit of meaning rather than a phonetic sound. And Wang Zhi, the Chinese captain, was a Confucian scholar. The Chinese characters allowed Nishimura and Wang Zhi to comprehend the same written idea without speaking the same language.

So they did something that is, in retrospect, one of the most quietly remarkable acts in the recorded history of first contact between cultures. Nishimura took a stick and knelt down at the water's edge. He drew Chinese characters in the sand. Wang Zhi, looking down, understood them. He wrote back. A conversation began between two men with a stick and a strip of shoreline.

Nishimura learned the essential facts. These strange pale men were merchants from the West. Their ship had been driven here by a terrible storm. They were not hostile. They needed repairs.

He sent word to his lords.

Part Three

The Meeting on the Shore

Lord and Stranger

The orders came back quickly. Shigetoki, the elder lord, directed that the foreign ship be steered around the island's southern tip to Akōgi, the modern city of Nishinoomote, the island's capital and main harbor. The junk was towed in. And two days after it had first dropped anchor in the cove of Maenohama, Tanegashima Tokitaka stepped aboard.

He was fifteen years old. He had never seen a European.

The chronicles that survive from the island, particularly the Teppōki, or Chronicle of the Musket, commissioned by the Tanegashima lords in 1606 to commemorate these events, preserve a vivid account of the sensation caused by the arrival of the Portuguese. The people of the island crowded to the harbor. The foreign men's appearance was a source of endless fascination. They ate with their fingers rather than chopsticks. Their clothing was unlike anything seen in Japan. The sounds they made to each other bore no relationship to any language anyone recognized. The local community, the Teppōki records with a touch of amusement, debated at length whether these men were human beings from a distant country or something else entirely.

The young lord, for his part, appears to have been transfixed, not by the strangeness of the men themselves, but by something they carried.

The Thunder Sticks

Among the trade goods on Wang Zhi's junk were objects that the Japanese had never encountered. They were long iron tubes, approximately a metre in length, attached to wooden stocks and fitted with a clever mechanism near the breech that used a smoldering cord, a matchlock, to ignite a small charge of powder. The Portuguese called them espingardas. The Japanese would eventually call them teppō, iron guns. We would call them muskets.

At some point during the days that followed, with Wang Zhi acting as the indispensable interpreter between Portuguese and Japanese, a demonstration was arranged. The arquebuses were loaded, powder down the barrel, a ball rammed home, the slow match lit and clamped in the serpentine. One of the Portuguese men took aim.

The shot, when it came, must have been extraordinary. Not merely the noise, though the noise alone would have been unlike anything the watching Japanese had heard, a detonation that belonged to a different order of magnitude than the bowstrings and arrows of their warfare. It was the effect. A solid iron ball traveling at a speed that made it invisible. Whatever it struck was destroyed. There was no defense.

Tokitaka understood immediately. This was not merely a curiosity, this was a revolution. He entered into negotiations.

The Price of History

The chronicles record that Tokitaka purchased two of the Portuguese matchlock arquebuses for the sum of 2,000 ryō. Translating historical currency values is always an exercise in informed guesswork, but most historians agree that this was an enormous amount of money, the kind of sum that represented a significant fraction of a small domain's annual revenue. For a fifteen-year-old lord who had only months before inherited power during a military crisis, it was an audacious expenditure.

The money changed hands. The muskets changed hands. The Portuguese, having survived a typhoon, lost a companion, landed in a country they had never heard of, and conducted an entire commercial negotiation through the medium of a Chinese pirate-scholar acting as interpreter, appear to have been reasonably satisfied with the outcome. The chronicles record them as cheerful, curious about their surroundings, and happy to demonstrate the weapons and explain their workings as best they could through Wang Zhi's mediation.

The Teppōki records that after their stay on the island, the foreign merchants departed on Wang Zhi's junk. They sailed away into the historical record, leaving behind two iron tubes, some instructions, and the seeds of a transformation that would reshape Japan more thoroughly than anything since Buddhism had arrived from the continent a thousand years before.

Part Four

The Men Behind the Myth

Who Were They, Really?

Fernão Mendes Pinto, the Portuguese adventurer whose famous autobiographical travelogue, the Peregrinação, claimed that he himself was among the first Europeans to land in Japan. Pinto was one of the great writers of the 16th century, a restless, observant, often brilliantly funny chronicler of the Portuguese maritime world, and his account of the first landing is extraordinarily detailed and vivid. He names his companions (Cristóvão Borralho and Diogo Zeimoto), describes their arrival in harrowing terms, and places the whole episode within a broader narrative of shipwreck and misadventure on the coast of China.

The problem is that his account cannot be true. Other records place Pinto in Burma at approximately the time he claims to have been in Japan. His memoirs were written decades after the events they describe, and Pinto had a well-documented habit of embellishment that was recognized even in his own lifetime. His name became something of a byword for tall tales in Portuguese. The scholarly consensus is that while Pinto almost certainly did visit Tanegashima at some point (he describes it too specifically and accurately to have simply invented it), he was not in the first landing party.

The men who actually were there, António da Mota and Francisco Zeimoto, are, ironically, far more obscure. They come out of obscurity, appear in the chronicles, and then vanish again. We know almost nothing about what became of them.

The Indispensable Intermediary

If any single figure deserves more attention than history has typically given him, it is Wang Zhi.

Wang Zhi, Wufeng, Gohō, are the names of the man without whom none of it would have happened. He was the captain who brought the Portuguese to Japan. He was the scholar whose written Chinese made communication possible. He was the interpreter who stood between Tokitaka and the strange men from the West and made the transaction comprehensible to both sides. Without Wang Zhi, the gun demonstration might never have been properly understood, the price might never have been negotiated, and the first chapter of European-Japanese relations might have ended in confusion and mutual suspicion rather than a commercial deal.

His later history is more dramatic and more tragic than his role in 1543 might suggest. He would go on to become the most powerful warlord of the Chinese maritime world, controlling a fleet of hundreds of ships and operating out of a fortified base in Japan, at a settlement called Hirado. He would eventually attempt to negotiate with the Ming authorities for the legalization of maritime trade, a negotiation that ended with his arrest, imprisonment, and execution in 1559. He died trying to open the world that he had done so much to connect.

The Boy Who Changed Japan

And then there is Tokitaka.

Tanegashima Tokitaka was fifteen years old when he bought the muskets. He would live to seventy-two, ruling his island for more than fifty years. He became, in the memory of his descendants and the historians who came after, a figure of almost legendary prescience, the young lord who looked at two iron tubes and saw the future of Japanese warfare.

This is not entirely unfair. What is remarkable about Tokitaka's response to the muskets is not simply that he recognized their potential, presumably others saw the demonstration and understood that these weapons were dangerous. What is remarkable is what he did next.

Immediately after purchasing the arquebuses, he summoned his master swordsmith and ironworker, a man named Yaita Kinbee Kiyosada, and commanded him to reverse-engineer the weapons. He gave his retainers orders to study the manufacture of gunpowder. He did not treat the muskets as treasures to be locked away and displayed. He treated them as problems to be solved, as blueprints to be decoded.

This instinct, to copy, to reproduce, to domesticate the foreign technology rather than simply possess it, was not only shrewd. What he did was plant the seed of an industry that would change warfare in Japan during a period of profound change.

Part Five

The Fire Spreads

The Puzzle of the Breech

Yaita Kinbee was a skilled craftsman. Japan in 1543 was already a world leader in iron and steel working, the katana blades produced by Japanese smiths were, by any technical measure, among the most sophisticated cutting weapons ever made, and the metallurgical knowledge required to produce them was deep and subtle. When Yaita examined the Portuguese muskets, he found that he could replicate most of what he saw. The iron barrel presented no fundamental difficulty. The wooden stock was straightforward. The serpentine and trigger mechanism were unfamiliar but not beyond analysis.

The problem was a single component: the breech plug.

At the base of the barrel, closing off the chamber where the powder burned, was a threaded iron screw. It was this screw that contained the explosion and directed its force down the barrel toward the ball. Without it, or with an imperfect version of it, the gun would be useless at best and lethal to its operator at worst. And Yaita, for all his skill, could not immediately work out how to forge and thread iron in the way the Portuguese had done.

He tried. He experimented. His first attempts failed. The chronicles record his frustration.

Salvation arrived the following year, 1544, in the form of more Chinese junks carrying Portuguese, one of the earliest instances of what would become a regular pattern of Portuguese traveling to Tanegashima and the other southern Japanese islands in the 1540s. This ship carried, among its crew or passengers, a blacksmith. And this unnamed blacksmith, in what must have been a remarkable session of cross-cultural technical instruction (conducted, presumably, through some combination of Wang Zhi's network of interpreters and the universal language of demonstration), taught Yaita how to forge the breech screw.

From that moment, Japanese manufacture of the musket was underway.

The Shuttle on the Loom

The Teppōki, writing about the transformation of Tanegashima in the years immediately following the arrival of the Portuguese, uses an image that is simple and exact. It records that merchants from the south and traders from the north came to the island's capital of Akōgi as continuously as the shuttle on a loom.

This is not mere rhetorical ornament. Tanegashima had become, almost overnight, a hub of military-commercial activity of a kind it had never previously experienced. The new weapons required gunpowder, and gunpowder required saltpeter and sulfur and charcoal in specific proportions. The island facilitated the import of saltpeter and lead from China and the Ryukyu Islands. The smiths of the island, trained in the new techniques, began producing muskets for export. The economic shock of all this traffic was, by the standards of a small island domain, enormous.

The gun-making tradition that emerged on Tanegashima in those years became one of the most respected in Japan. The island's smiths founded what came to be known as the Tanegashima-ryū, the Tanegashima School of gunsmithing, whose techniques were studied and emulated across the country. The same island that produced distinctive scissor blades and kitchen knives, worked in the particular tradition of iron-sand metallurgy that the Taira clan craftsmen had brought to Tanegashima after their defeat at the hands of Minamoto no Yoritomo in the 12th century, now produced the weapons that would end the age of medieval Japanese warfare.

From Island to Empire

The spread of the musket from Tanegashima to the rest of Japan is a striking example of how rapidly a transformative technology can propagate when the conditions are right.

The first vector was commerce. A merchant from the wealthy self-governing port city of Sakai, near modern day Osaka, happened to be on Tanegashima when the first guns were demonstrated. He learned to shoot and learned to mix gunpowder. He brought the knowledge back to Sakai, already a major center of metalworking and trade, which quickly became Japan's primary industrial hub for mass-producing muskets. The connections between Tanegashima, the Tanegashima clan's long-standing relationship with the Hosokawa family, and the trade routes that ran through the Honnō-ji Temple in Kyoto all helped to accelerate this diffusion.

Another early vector was religious, or at least ecclesiastical. A musket made its way to the Negoro temple complex in Kii Province, home to the warrior monks known as negoro-shū, whose mercenary armies were among the most formidable in Japan. Aided by a smith from Sakai, the Negoro monks began mass-producing the weapon for their own forces.

To the south, the path was even more direct. Tanegashima was a tributary domain of the Shimazu clan of Satsuma, the most powerful lords of southern Kyushu. The new weapons reached the Shimazu almost immediately, and Lord Shimazu Takahisa deployed them in battle as early as 1549, only six years after they had first arrived on the junk in Maenohama cove. The Portuguese themselves, sailing along the Kyushu coast in subsequent years, introduced firearms directly to other major domains: the lords of Bungo (North Eastern Kyushu) and Hirado (North Western Kyushu), among others, were early and enthusiastic adopters.

Political connections carried the musket to central Japan. Lord Tokitaka, the Shimazu, and the Otomo all presented muskets as diplomatic gifts to the Ashikaga Shogun in Kyoto. Recognizing the weapons' value, the Shogun distributed them to smiths in the Yamashiro and Omi regions for copying. The city of Kunitomo, in Omi Province, rapidly became a production center to rival Sakai, eventually housing hundreds of artisans forging guns under direct shogunal patronage.

Nagashino: The World That the Junk Made

The culmination of this process came thirty-two years after the junk anchored at Maenohama. On June 28, 1575, at a place called Nagashino, in what is now Aichi Prefecture, the warlord Oda Nobunaga deployed three thousand musketeers against the cavalry of the Takeda clan.

The Takeda were among the most feared mounted warriors in Japan. Their cavalry charges, perfected over generations, had broken armies across the country. They rode that day against wooden palisades, behind which Nobunaga's ashigaru, foot soldiers drawn from the peasantry, stood with muskets.

Nobunaga had organized his musketeers into rotating ranks. While one rank fired, another reloaded, and another prepared. The effect was a continuous rolling volley that the charging cavalry could not survive. The Takeda were destroyed. Three of their greatest generals died on the field. The age of the mounted samurai warrior as the decisive force in Japanese warfare ended that afternoon.

By the end of the 16th century, Japanese armies fielded muskets in proportions that exceeded many contemporary European forces. Gunners comprised roughly a third of all daimyo armies. The proliferation of firearms broke the localized feudal stalemate that had kept Japan in a state of chronic civil war for over a century, enabling Nobunaga, his successor Toyotomi Hideyoshi, and finally Tokugawa Ieyasu to consolidate power and achieve what decades of cavalry and swordsmanship had not: the unification of the Japanese archipelago.

All of it traces back to a storm, a damaged junk, and a fifteen-year-old lord who recognized what he was looking at.

Epilogue

The Island That Remembered

Tanegashima today is a quiet place. Its population has been falling for decades, from over fifty thousand in 1970 to fewer than thirty thousand now, a decline that mirrors the hollowing out of rural Japan more broadly. The traditional craft industries that gave the island its historical character, the knives and scissors worked in the unique tradition of Kyoto craftsmen brought here during the Taira exile, the iron-sand metallurgy that made the island famous, survive, but under pressure. Tourism helps. So does the presence of the Tanegashima Space Center, Japan's largest space development facility, which sits at the southeastern tip of the island and sends rockets into orbit only a few miles from where Wang Zhi's junk once came to anchor.

The lords of Tanegashima understood the importance of what had happened on their island. In 1606, sixty-three years after the event itself, they commissioned a scholar named Nanpo Bunshi to write the Teppōki, the Chronicle of the Musket, to ensure that the memory of 1543 would not be lost. The chronicle is a work of deliberate commemoration, shaped by the political interests of the Tanegashima clan, who had every reason to want history to remember them as the men who had brought firearms to Japan.

For firearms were indeed known throughout Japan as tanegashima for generations after 1543. In the popular imagination, the island and the weapon became synonymous. That a small, peripheral island of thirty thousand souls gave its name to one of the most consequential military technologies in Japanese history is an extraordinary thing.

Today, a plaque remains in Tanegashima, erected in 1983, with an inscription in the memory of the Portuguese sailors who arrived there in 1543. It reads "Em Memoria dos Navegadores Portugueses que no sec XVI aportaram a esta terra".

"The people of the island know not yet the use of firearms, and when they see the result of shooting, they clap their hands with admiration."
