The Man the Jesuits Never Named: What the Sources Actually Say About Yasuke, 1579–1582

The Scrubbing

Oda Nobunaga's First Meeting with Yasuke, 27 March 1581

In the last week of March 1581, in a temple compound in central Kyoto, the most powerful man in Japan ordered a stranger stripped to the waist and washed in front of witnesses.

The stranger was an African man in the service of the Jesuit mission. Oda Nobunaga, who had spent twenty years dismantling the political order of his country and was not in the habit of accepting other people's accounts of anything, had been told that the man's skin was black. He did not believe it. The obvious explanation, to a man who had seen lacquer, ink, dye, and the theatrical cosmetics of the capital, was that somebody had painted him. So he had him undressed and scoured with water, and watched.

The color stayed.

The meeting is recorded twice, from two directions, by parties who had no opportunity to coordinate. Ōta Gyūichi, Nobunaga's own administrative vassal and the compiler of the Shinchō-Kō ki (信長公記), the book-by-book chronicle of his lord's life, wrote it into the entry for the twenty-third day of the second month of Tenshō 9. Luís Fróis, the Portuguese Jesuit who wrote more about sixteenth-century Japan than any other European alive, wrote it into a letter dated 14 April 1581.

Almost nothing else about this man enjoys that kind of double attestation.

Tenshō 9.2.23 converts to 27 March 1581 by the calendar analysis most historians of the mission have followed.

What the chronicle records next is the part that mattered. Nobunaga was satisfied. It described the man as healthy and good-looking, gave his strength as greater than that of ten men, and noted that his skin was black like that of an ox. It gave his age as roughly twenty-six or twenty-seven by Japanese reckoning, which counts a newborn as one year old, with a Western equivalent somewhere in the middle twenties. The sources render the figure inconsistently, and the chronicle itself is plainly offering an approximation rather than a birthdate.

Then Nobunaga took him into his service and gave him a name.

He called him Yasuke. No source, Japanese or European, offers any etymology for the word.

The Riot at the Gate

The 1581 Crowd at the Jesuit Residence in Kyoto

Before the audience there was a riot, and the riot is the reason the audience happened.

Fróis's letter of 14 April 1581 describes what occurred outside the Jesuit residence in Kyoto when word spread that the visiting Father Visitor's retinue included an African. The crowds came, and then kept coming, and then stopped behaving like crowds. They broke down the gates.

Nobunaga was lodging at Honnō-ji, a temple roughly a block from the Jesuit residence, when the disturbance reached its height. He sent for the man. Father Organtino Gnecchi-Soldo, the Italian who ran the Kyoto mission, escorted him.

None of this was unprecedented. Thirty-four years earlier, at Yamagawa in Satsuma, the Portuguese captain Jorge Álvares had noted in the report that gave Europe its first sustained portrait of Japan that Japanese people were traveling fifteen to twenty miles to look at the black slaves aboard the Portuguese ships. The record does not preserve any of their names. The Kyoto frenzy of 1581 was a repetition of a known pattern at a much larger scale, in a much bigger city, in front of a man who collected extraordinary objects and extraordinary people with equal appetite.

Nobunaga asked Valignano for him. Fróis, writing on 5 November 1582 from Kuchinotsu, confirmed the transfer and was specific about the mechanism: the Father Visitor turned the servant over at the warlord's express request.

Valignano handed him over. He never wrote a word explaining why.

The Man Who Came in the Retinue

How Yasuke Arrived in Japan with Valignano in 1579

He arrived in Japan in 1579, in Kyūshū, as part of the entourage of Alessandro Valignano, the Neapolitan aristocrat sent east as Visitor with authority over every Jesuit enterprise from Mozambique to Japan. Fróis's notice contains the first European reference to him, and it is not a biographical one. The crowds, Fróis wrote, marveled at the height of the Father and at the blackness of our Moor.

That sentence does a great deal of work. It establishes that he was present, that he was conspicuous, and that the Jesuits thought of him as a possession. Moretto, "our Moor," "Cafre," from the Arabic kāfir by way of the Portuguese slaving vocabulary of the Indian Ocean: these are the words Fróis uses. They are not names. In the entire European archive, across every letter and chronicle and printed compilation, no Jesuit ever calls him anything.

"Yasuke" is a Japanese name given by a Japanese warlord and preserved only in Japanese documents.

His status on arrival was unfree. Jesuit correspondence of the period uses "black slave" and "negro slave" of African attendants as a matter of ordinary bookkeeping, and C. R. Boxer, working through the mission's own records, established that the staff of Jesuit residences in Japan routinely included slaves described as Negroes, Indians, Malays, and other Asiatic and African ethnicities. The Society of Jesus in Asia ran on the same labor as everything else in Portuguese Asia. It debated the ethics of the traffic at length, repeatedly, and with real anguish in the councils it convened at Nagasaki, and it went on holding the people it held.

Africans in Japan were not rare. Africans in Japan who acquired names, wages, houses, and swords were rare enough that only one is recorded.

The population he belonged to is documented well enough to sketch. In December 1593, Katō Kiyomasa mentioned a retainer called Kurobō, from Mozambique, who had a Japanese wife and children back in Higo. In 1604, in the division of the estate of Roque de Melo, a former Captain-General of Macau, at Serpa in Portugal, a slave named Francisco Preto appears in the inventory, probably born in Mozambique. Richard Cocks, running the English factory at Hirado, repeatedly noted African servants in his own household, spelling it "Caffro." A man called Francisco appears in the Nagasaki trade registers in 1630 with his origin given, with a question mark, as Mozambique. Africans appear on the folding screens that Japanese artists painted of the Southern Barbarians, carrying parasols and leading horses, generally in the middle distance.

The 1603 Vocabulário da Língoa de Iapam, the Jesuit dictionary printed at Nagasaki, defines Curobŏ simply as "Cafre," a black man. At the time it carried no insult. It curdled into the derogatory kuronbō only in the eighteenth century, long after everyone who had used it neutrally was dead.

What the Maeda Draft Says

The Maeda Draft of the Shinchō-Kō ki: Stipend, House and Sword

Everything anyone believes about Yasuke's rank rests on a paragraph that was cut.

Ōta Gyūichi's chronicle went through drafts. The version that came down as the standard published Shinchō-Kō ki, rated among the most reliable Japanese sources for the period, contains the Kyoto entry, the age, the ox comparison, the strength of ten men. It contains nothing else. No stipend. No residence. No sword. No title. No duties. And after 1581 it says nothing about him at all, ever again, including at Honnō-ji, where its own protagonist died.

An earlier manuscript survived in the archives of the Maeda family. It reads:

"This black man called Yasuke was given a stipend, a private residence, etc., and was given a short sword with a decorative sheath. He is sometimes seen in the role of weapon bearer."

That is the whole of it. Four details, one sentence and a fragment, in a document that an editor decided not to keep.

The details reward slow reading. There is no number attached to the stipend, only the word and an "etcetera" that suggests the compiler was summarizing a list rather than transcribing one. A private residence meant a household, which meant a man who was maintained rather than merely fed. The short sword with a decorated sheath was a wakizashi, the companion blade, and the decoration is the operative word: an ornamented sheath was a gift of regard, not an issue of equipment. A weapon bearer walked behind the lord carrying his sword or spear, close enough to hand it over, a position of trust and proximity rather than of command.

The sources disagree about which document carries these four details. One line of reading assigns the weapon-bearer role to the standard chronicle and to Fróis as well; the more specific reading holds that all four exist only in the Maeda draft and are absent from the published text entirely. Both cannot be right, and the question is not trivial, because it determines whether the status evidence comes from one manuscript or from three independent places.

What is not in dispute is that the stipend is attested twice, and the second attestation is the more remarkable of the two.

Matsudaira Ietada was a senior samurai and a Tokugawa vassal who kept a private diary. In the spring of 1582, April or May, he was present during Nobunaga's triumphal tour of the newly conquered Takeda territories, and he met Yasuke there. He wrote:

"Lord Nobunaga gave the black man who the missionaries presented to him, a stipend. His skin was black like ink and he was around 6 shaku 2 bu tall. He was called Yasuke."

Six shaku two bu works out to roughly 182 centimeters, an extraordinary height against sixteenth-century Japanese norms and a notable one against sixteenth-century European ones. Ietada was a soldier writing for himself, with no mission to promote and no chronicle to shape, and his diary was not published until 1897.

That last fact is the load-bearing one. A document that sat unread in a family's possession for three centuries cannot have been contaminated by the Jesuit letters, and the Jesuit letters cannot have been contaminated by it. Two entirely separate traditions record the same wage.

The Word That Is Not There

Do the Sources Call Yasuke a Samurai?

No sixteenth-century document, Japanese or Jesuit, calls Yasuke a samurai.

Not the Shinchō-Kō ki, which calls him a kuro-bōzu (黒坊主), a black page or black acolyte, a word built from the vocabulary of temple servants. Not the Maeda draft, which calls him "this black man called Yasuke." Not Matsudaira Ietada, who calls him "the black man." Not Fróis, who calls him moretto and "our Moor" and "Cafre." Not Lourenço Mexia, whose single passage will be dealt with shortly. The word samurai does not appear. Neither does bushi. Neither does kashin, the ordinary term for a retainer.

This is the kind of finding that both sides of a public argument tend to hear as a victory, and neither of them should.

What is absent is a word. What is present is a set of material facts, and in Sengoku Japan those facts had meanings. A stipend was how a warrior was maintained. A private residence was how a retainer of standing was housed. A sword with a decorated sheath, given by a lord, was a mark of favor within the warrior class and not outside it. Service as weapon bearer was a military function performed in armed proximity to the person of the lord. Take those four things together in 1582 and you are describing the customary apparatus of warrior status, which is precisely why modern historians classify him as a samurai and why the classification is defensible.

It is a classification. It is not a quotation.

The honest formulation is that "samurai" is a defensible modern label for a man who held the recognized material privileges of the warrior class, applied by historians as an inference from attested privileges, and never found in any surviving sixteenth-century text. The strong popular claim, that the sources say he was a samurai, is false. The strong revisionist claim, that there is no evidence of any status at all, is also false, and requires ignoring two independent records of a wage.

The way the error propagates is instructive. A modern secondary work, Danny Chaplin's Sengoku Jidai, states that Nobunaga elevated him to the rank of samurai, in a paragraph adjacent to a citation of the Shinchō-Kō ki. Downstream, the characterization and the citation travel together, and a modern author's judgment acquires a sixteenth-century footnote. Nobody forged anything. A gloss migrated into the space where a source belonged, which is how most bad citations are born.

The argument, stripped of its heat, is almost entirely definitional. There is very little disagreement about what the surviving documents say. There is enormous disagreement about whether stipend plus residence plus sword plus weapon-bearer role earns an English word that hardened, long afterward, into a category sixteenth-century Japan applied far more loosely than any modern reader assumes.

The Rumor in Azuchi Town

Lourenço Mexia's 1581 Letter and the Rumor of a Title

Lourenço Mexia was Valignano's right-hand man, and he went with him to Azuchi in 1581, to the great black-and-gold castle on Lake Biwa where Nobunaga had staged the theological debate he had already decided the outcome of two years earlier. Mexia mentions Yasuke once.

It is the single most consequential Jesuit notice in the entire controversy.

"Nobunaga never tired of talking to him."

"As he was also strong and entertaining, he pleased Nobunaga."

And the talk circulating, which Mexia reports as talk: that Nobunaga would make him Tono, a lord in his own right.

That is the whole of what any Jesuit ever wrote about Yasuke's standing. He records no stipend, no residence, no sword, no appointment. The only status term he supplies is the highest one anybody applies to Yasuke in any language, and he attributes it explicitly to rumor.

The first two fragments are, in their way, more informative than the third. "Nobunaga never tired of talking to him" implies conversation, sustained and repeated, which implies a shared language, which implies that within a year or two of arriving, a man brought to Japan as an unfree attendant in a missionary's baggage train was holding the attention of the most feared political operator in the archipelago well enough that a visiting priest thought it worth reporting to Europe. Nobunaga did not tire of talking to very many people. He was famous for the opposite.

"Strong and entertaining" is a colder phrase, and it should be allowed to stay cold. Nobunaga collected. He collected tea utensils with a ferocity that distorted the market for them, he collected the outward apparatus of Christianity without any interest whatsoever in its content, and the portrait of him that emerges from every source is of a man whose curiosity was total and whose attachments were provisional.

The Silence of Alessandro Valignano

Why the Jesuit Who Brought Yasuke to Japan Never Wrote About Him

Alessandro Valignano wrote a great deal. He wrote the Sumario, he wrote the Advertimentos, he wrote the accommodation policy that remade the entire Japan mission around the proposition that Europeans should adapt to Japanese manners rather than the reverse, and he wrote letters by the hundred.

He never wrote about Yasuke.

He does not name him. He does not describe what he did in the Jesuit household, whether he was a valet, a bodyguard, a bearer, or something else. He does not say where he came from, how long he had been with the Society, where he was acquired, or what he cost. And he never explains why, in the spring of 1581, he gave away a member of his own retinue to a Japanese warlord.

The descriptions that circulate, "valet," "entourage servant," are modern summarizers' words filling a hole in the archive. The phrase "black slave" does appear in Jesuit correspondence of the period as a general usage, but not in anything of Valignano's own about this particular man.

The closest he comes is oblique to the point of being eerie. De Missione Legatorum Japonensium, the Latin dialogue assembled from the diaries of the four boys of the Tenshō embassy and printed at Macau in 1590, contains in its fourteenth colloquium a discussion between two of the characters, Leo and Lino, on what they call the generative cause of dark skin. The question, as they frame it, is a theological one: if all humanity descends from Adam and Eve, how did some people come to be black? They work through the possibilities with the seriousness that sixteenth-century natural philosophy brought to problems it had no tools to solve.

It is plausible that the sensation of 1581 prompted the passage. It is not biography. Valignano, who had shared a household and a sea voyage with an African man for at least two years, treated dark skin as a specimen problem for philosophical dialogue rather than as a matter concerning someone he knew.

The same dialogue contains something that complicates any tidy reading of Jesuit attitudes. The four young Japanese noblemen, describing what they saw in Portugal and Spain, note the Ethiopians serving at Portuguese tables, and they express deep sorrow at Portuguese merchants trafficking Japanese men and women out of their own country. The traffic in Japanese people ran in the opposite direction from the traffic that had brought Yasuke to Kyoto, on the same ships, under the same flag, and the boys had noticed.

Francis Xavier had set the terms of the Jesuit view three decades earlier, before he ever saw Japan. Writing of his expectations for the mission he was about to found, he judged that he would find more fruit there because the Japanese were white and governed by reason, and so different from all the black people he had encountered in Africa and India.

The Society that produced that sentence produced the men who brought Yasuke to Japan. It is not necessary to editorialize about the connection.

The Last Day at Nijō

What Yasuke Did at Honnō-ji and Nijō, and How He Surrendered

On 21 June 1582, Akechi Mitsuhide turned an army of thirteen thousand men, ostensibly marching west to reinforce the campaign against the Mōri, toward Kyoto instead, and surrounded Honnō-ji with Nobunaga inside it and a guard of a few dozen. Nobunaga died in the burning temple. His body was never recovered, which would generate four centuries of speculation and at least one persistent claim about Yasuke.

Everything known about Yasuke's part in that day comes from Luís Fróis.

Fróis's account, carried in the letter of 5 November 1582 and compiled into the Jesuit Annual Letter of 1583, runs as follows. Yasuke got out of Honnō-ji. He made his way across the city to where Nobunaga's heir, Oda Nobutada, had taken up a defensive position, at the Nijō palace, or possibly at the Myōkaku-ji quarters; the sources are not consistent about which. He joined Nobutada's guard. He fought there, and then he surrendered his sword.

The victors did not know what to do with him, so they asked.

Mitsuhide's answer, as Fróis renders it, was contemptuous. The man was a beast who knew nothing, he was not Japanese. On those grounds, Mitsuhide declined to kill him and ordered him delivered to the Nanbanji, the Jesuit church in Kyoto.

That is the last event in his life that any document records.

The Fróis version has been repeated for four hundred years, and it has an internal architecture that ought to make a careful reader pause. The insult and the mercy are a matched pair. Dismissing the prisoner as a foreigner is precisely what makes sparing him defensible rather than shameful, in a context where the ordinary disposition of a defeated enemy retainer was not clemency. The reasoning is too neat, and it arrives in direct quotation, in a letter written by a man with an institutional interest in portraying the Nanbanji as a sanctuary of mercy in the middle of a pagan coup, four and a half months after the fact, from a town four hundred miles away.

That does not make it false. Fróis was well informed and his Kyoto colleagues were on the spot. But quoted speech is exactly the point in the narrative where a mission's interests and a historian's evidence become impossible to separate, and whether that dismissal is Mitsuhide's contempt or Fróis's framing is not recoverable.

The Interest of the Man Holding the Pen

How Reliable Are the Jesuit Letters as Sources?

Because the most dramatic episode in Yasuke's life survives in exactly one source, and that source is a Jesuit letter, the question of how far Jesuit letters can be trusted stops being a methodological preliminary and becomes the whole argument. The scholarly verdict is genuinely split.

For the defense: C. R. Boxer observed that the letters have long been recognized as primary sources for a crucial stretch of Japanese history, and that Japanese historians of the first rank rated the correspondence very highly. John Correia-Afonso found that modern research has confirmed the Jesuit accounts to be, on certain disputed points, more correct than the native chronicles. Mihoko Oka regards their data on trade and East Asian political dynamics as excellent and reliable.

For the prosecution: Jeroen Lamers allowed that the letters were founded on solid firsthand information and then flatly called them not good reportage, garbled in their information and prone to exaggeration and invention. Mihoko Oka, who defends their commercial data, notes that they were written to promote evangelical achievement and secure continued funding, and consequently tended to abbreviate or omit inconvenient material. Ikuo Higashibaba warns that they were composed for missionary political purposes and require reading with caution and reasonable skepticism. James Murdoch, writing his History of Japan at the start of the twentieth century and never one for diplomatic phrasing, held that Fróis and his contemporaries handled truth carelessly and doled it out with sparing economy.

Both verdicts are correct about different things. The letters are excellent on what a Jesuit saw with his own eyes and had no reason to shade: prices, distances, ship movements, court procedure, the number of gates broken. They are unreliable on conversion figures, on the disposition of powerful men toward the faith, and on anything where a European reader's willingness to fund the enterprise was at stake.

Applied to Yasuke, this sorts the evidence usefully. Fróis on the riot, the scrubbing, the summons, the escort, and the dates is exactly the sort of testimony he was good at. Fróis on the transfer at Nobunaga's express request is administrative and unflattering to nobody. Fróis on Mitsuhide's exact words at the fall of Nijō is precisely the sort of testimony he was bad at.

The record does not permit better than that.

Mozambique, or Somewhere Up the Nile

Where Was Yasuke Born? Mozambique and the Dinka Hypothesis

No sixteenth-century document states where he was born. Not one.

Two reconstructions occupy the space, and they are incompatible.

The first, and much the older, is Mozambique. It appears in François Solier's Histoire ecclésiastique des isles et royaumes du Japon, a Jesuit compilation written in the 1620s, decades after the events and at second or third hand from the correspondence. Its strength is that it fits the plumbing of the Portuguese empire exactly. The slaving route ran Mozambique to Goa to Malacca to Macau to Nagasaki, the same seasonal circuit that carried the silk, and Mozambique was the ordinary source of African servants throughout Portuguese Asia. Every other African identified by origin in the Japanese record, Katō's Kurobō in 1593, Francisco Preto in 1604, the Francisco of the 1630 Nagasaki registers, is given as Mozambique or probably Mozambique.

The second is the Dinka hypothesis, advanced by Thomas Lockley in African Samurai. It rests on physical description and elimination. The Makua peoples of Mozambique, Lockley argues, tend to be shorter and lighter-skinned than the man the Japanese sources describe; the recorded ink-black skin and the 182-centimeter height fit the Dinka of the southern Nile, among the tallest and darkest-skinned peoples in Africa. Lockley concedes, in his own notes, that there is no direct evidence, and presents the argument as deduction rather than documentation.

Neither reconstruction rests on a contemporary source. One is a seventeenth-century Jesuit assertion by a man who was not there, working from letters that do not say it. The other is a twenty-first-century inference from two physical details recorded by observers measuring by eye. The principle that separates source wording from later interpretation applies to the birthplace as much as to the word samurai, and it produces the same answer: the record does not preserve it.

The name is equally opaque. Nobunaga gave it, no source explains it, and the etymologies in circulation are modern guesses. The Japanese also used Tenjikujin, literally people of Tenjiku, meaning India, as a loose catch-all for the dark-skinned attendants who arrived with Europeans, which suggests the geography was not of pressing interest to anyone in sixteenth-century Japan either.

He came from somewhere in Africa, on a Portuguese ship, unfree. That is the extent of it.

Six Ways to Continue a Life

The Six Later Claims About Yasuke, and What Backs Them

After the autumn of 1582 there is no verified record of him anywhere in the world.

This is intolerable to narrative, and so the gap has been filled repeatedly. Lockley canvasses six continuations, and rates most of them weak in his own text, which has not prevented them from circulating without the caveats attached.

The first has Yasuke carrying Nobunaga's head out of the burning Honnō-ji, thereby explaining why Mitsuhide never produced it and never established that his coup had succeeded. The evidence is Oda family lore. Lockley's own formulation is that there is no evidence for Yasuke having taken Nobunaga's head, however Oda family lore has it so, which is a sentence doing considerable work in a small space.

The second places him at Okitanawate in 1584, as an African gunner in the Arima and Shimazu force. Fróis describes that battle vividly, including the gunners brought up from Nagasaki who knelt to pray before firing, which is the kind of detail he was very good at. He never places Yasuke among them. Lockley allows that the gunner may have been another man entirely.

The third is Katō Kiyomasa's Kurobō, the retainer with the wife and children in Higo. The difficulty is in the name itself. Kurobō was the generic word for any African in Japan, roughly equivalent to writing "the black man" and expecting it to identify someone. It is a description, not an identification.

The fourth is a retainer recorded in a document of the 1670s, serving under Kamei Korenori at Shikano in Inaba province, described as a kurobō seven shaku tall and black as an ink stone. The generic-name problem applies again, and the document postdates the events by a century. There is also an arithmetical objection that the height-based reasoning behind the Dinka hypothesis ought to find fatal: seven shaku is roughly 212 centimeters, some thirty centimeters taller than the 182 attested for Yasuke by a man who stood next to him. If height identifies a man, it also disqualifies one.

The fifth concerns Tamaki Mitsuya, a samurai photographed in Paris in 1864 as part of a Japanese delegation, whose features in the photograph have been read as African. Lockley's verdict is unambiguous: there is absolutely no proof Yasuke was Tamaki's ancestor.

The sixth is simply that he left. Back to Macau, back to Goa, or into the African guard of the Macau merchant Bartolomeu Vaz Landeiro, or into the fleet of the pirate Zheng Zhilong. No document connects him to any of them, and no caveat is required, because there is no positive evidence at all.

Every one of the six is an argument from plausibility about a man for whom no plausibility argument has ever been tested against a document. He was thirty or so in the summer of 1582, in a country where his associations had just become lethal liabilities, in the care of an order that would be expelled from the capital within five years. He may have died of his injuries that summer. He may have sailed out on the next carrack. Nobody will ever know.

The Argument Over a Word

The Five Documents That Record Yasuke

What survives is five documentary witnesses, and none of them is long.

The published Shinchō-Kō ki supplies the arrival, and then silence. The Maeda draft supplies the stipend, the residence, the decorated short sword, and the weapon-bearer role, in a passage an editor removed. The diary of Matsudaira Ietada supplies the stipend again, independently, and the height, and was not read by anyone outside one family until 1897. Fróis supplies the retinue, the riot, the audience, the transfer, and the last day. Mexia supplies three fragments about conversation and one rumor about a title. The 1584 Roman compilation Alcune lettere delle cose del Giappone corroborates the Kyoto episode at pages 136 and 137, but it is a compilation of the same mission's correspondence and transmits Fróis rather than standing beside him.

The Japanese documents record what he was given. The Jesuit documents record how he arrived and how he left the stage. Mexia alone speaks to what he was in between, and Mexia is reporting gossip.

Every popular account of Yasuke, in whatever medium, is an interpolation between five points on a graph covering roughly fifteen months. The 2021 Netflix and MAPPA anime keeps the height, the dark skin, the service under Nobunaga, and the washing incident, and then introduces war machines, magic, an invented antagonist, and a supernatural grandmother installed as ruler of Japan in place of Toyotomi Hideyoshi. The 2025 study that cataloged those departures is right that adaptation introduces the figure to audiences who would otherwise never hear of him, and that viewers have to do the separating themselves. It also dates the first meeting with Nobunaga to 1582, which is wrong by a year, and which is a fair indication of how far the chronology drifts once it leaves the documents.

Both camps in the modern argument have accepted a question the sixteenth century never asked, and then fought over the answer with an intensity the surviving evidence cannot support in either direction. The men who wrote these documents were not adjudicating a category. Ōta Gyūichi was recording what his lord did. Matsudaira Ietada was noting a striking thing he saw on campaign. Fróis was writing to Rome about a riot, a warlord, and a coup.

None of them thought the interesting question was what to call him. Nobunaga, who did the actual naming, gave him a Japanese name and a Japanese wage and a Japanese sword, and appears to have found him worth talking to more than he found most people worth talking to, and that is as close to a verdict as the sixteenth century offers.

The Jesuits who brought him across two oceans wrote down the height of the crowds.

They never wrote down his name.
