Abstract

Based on Japanese and Portuguese sources, this paper aims at recovering local categories of bondage in order to identify mechanisms by which people were subjected to bonded labour in early modern Japan. The analysis focuses on crossing local forms of bondage, here referred to as genin, and the processes of subjecting individuals to this condition, the so-called called geninka, with the European notion of slavery and enslavement. Local forms of subjection to bondage are drawn from the analysis of early seventeenth-century Tokugawa legislation dedicated to the suppression of human trafficking networks. These documents use a number of labels such as genin, hōkōnin, wakatō, chūgen, hikan, and komono, all references to people subjected to various forms of bondage. At the same time, a crucial debate among members of the Society of Jesus in India offers the opportunity to scrutinise the application of the historical and legal European concept of slavery and enslavement to Japan, a region beyond the secular authority of colonial empires. Ultimately, slavery reveals itself as one of the many categories used by early modern actors to interpret and regulate labour arrangements in the budding Christian communities created by missionaries in the Iberian world.

Introduction

By the end of the sixteenth century, Japan was reaching the end of a long process of commodification of labour that had been intensified by the great famines of the thirteenth century.Footnote 1 Individuals who were subjected to the ownership of others were generally known as genin (lower person), a comprehensive term found in historical sources and Japanese scholarship. Similar to the Portuguese cativo, the term has been employed to denote a person subjected to one of the many forms of dependent relations of medieval Japan, such as shojū, nubi, zōnin, and shimobe. Footnote 2 By the late 1500s, however, contracts of limited-time bondage, according to which one agreed to work for someone else for a number of years in exchange of a small sum of money, but not necessarily become property of another person, were increasingly becoming the norm. Known as nenki hōkō (temporary service), these arrangements were ubiquitous during the Edo period (1600–1868), when such contracts became highly specialised.Footnote 3 The process was intensified by the legal separation between farmers and the military promoted between the late sixteenth century and the early seventeenth century, which resulted in a highly hierarchised Japanese society.Footnote 4

This period also coincided with the arrival in Japan of Iberian merchants and Jesuit missionaries, who promptly equated the various local forms of bondage for money with slavery. Eventually, this process was consolidated by the Japanese invasions of the Korean peninsula between 1592 and 1598. As a result of this equation and the encounters between European merchants and local traders, local and regional human trafficking networks, previously restricted to the waters between the Japanese islands and the shores of China and Southeast Asia, were then integrated into the ever-expanding global slave-trade network of the early modern period.Footnote 5 After decades of tacit acceptance and cooperation with the trade, the increasingly dangerous political environment of the late sixteenth century led the missionaries of the Society of Jesus to condemn the trade altogether.Footnote 6

The focus of this article is the process of subjugating an individual into bondage, which I refer to as enslavement on the European side and, on the Japanese side, as geninka—the transformation of an individual into a genin. Footnote 7 Methodologically speaking, this is not an attempt to bring a category from Japanese studies to the historical debate, but rather a proposition to complicate the discussion through seizing local, underappreciated categories without overpowering these same ideas through the imposition of European categories.Footnote 8 As a result, it becomes possible to identify two distinct moments of the process of subjugation: first, the capture, alienation, kidnapping or self-sale of the individual and, second, their subjection to Western, alien practices of bondage. Inspired by the notion of intersection as envisioned by the proposers of the histoire croisée, this paper searches for connections and overlaps between the two distinct epistemologies in order to find how the trade itself worked and what aspects of local bondage and human trafficking were seized by the European-Japanese trade.Footnote 9 By identifying the mechanisms used by traffickers in Japan, the article will explore how the European slave trade interacted with local human trafficking networks and how this interaction supplied the small yet significant demands for bonded labour of Japanese origin in colonial societies. At the same time, seizing the privileged point of view of Jesuit theology, I highlight the complex process of recognition of the legal category of slavery in areas beyond the secular jurisdictions of early modern colonial empires and the importance of assessing historical definitions of bondage.

Scholars such as Thomas Nelson and Lúcio de Sousa have claimed that the late sixteenth-century Jesuit condemnation of the enslavement of the Japanese was the result of missionaries having witnessed the suffering of the enslaved. Also, it has largely overlooked that the central issue for Jesuits in Japan was not to save the souls of enslaved individuals themselves, but rather the salvation of those who claimed ownership over subjugated others in Japan.Footnote 10 This paper argues that, firstly, previous attempts to identify methods of subjugation in Japan have failed to notice the specificity of Japanese categories because of scholars’ conflation of all those terms with slavery as a universal label.Footnote 11 Furthermore, scholars have used Western and, at times, Japanese sources to identify these mechanisms but with no attention to the epistemological differences and the challenges these distinctions pose.Footnote 12 I argue that while a range of subordinate and bonded positions were available in medieval and early modern Japan, the dialogue between these categories and the European notion of slavery as a historical form of bondage is fundamental to better understand how these two worldviews interacted.

Japanese administrators were keen to regulate the Japanese market in labour, where human trafficking was abundant. Bandits lurked roads in search of victims to rob and kidnap, while others were captured in wars.Footnote 13 In the cities, too, many were at risk. In 1579, a woman in Kyoto was executed after confessing to deceiving, abducting, and selling more than eighty people.Footnote 14 The law also targeted traders selling captured Japanese to foreigners. After a series of prohibitions against local human trafficking enacted by Japanese ruler Toyotomi Hideyoshi (1537–98), authorities crucified Japanese traffickers by the docks of Nagasaki in the 1590s.Footnote 15 Besides kidnapping, there were also many who sought self-alienation as a solution in times of famine and other large-scale crises, an alternative that was tacitly accepted by central authorities and even championed by local administrators.Footnote 16 In the 1610s, the Tokugawa shogunate or Tokugawa Bakufu resumed the persecution of human traffickers, policy that had been abandoned temporarily due to the wars following the emergence of the new regime and the demise of the Toyotomi clan. Consequently, the second shōgun, Tokugawa Hidetada (1581–1632), enacted two prohibitions that underlined the many ways in which people could be hired, sold out, or kidnapped, inadvertently producing a detailed account of the practices of the time.

A second argument that I make here is that notwithstanding the above, a clash occurred between European ideas of slavery and Japanese notions of bondage, which included perpetual and temporary forms of coerced labour.Footnote 17 The idea of slavery held by the missionaries referred to a legal definition that was difficult to identify amidst the various intricacies and variables of common life in colonial societies and missionary fronts in general. Their project was, from a Foucauldian standpoint, to use the tension between the idealised servitus of European ius commune and the everyday forms of bondage to create ways to impose their own religious and political agendas on Christian communities. Thus, it is clear that they were resorting to one of the very few clear-cut contemporary definitions of slavery in their own debates, which allows scholars to work with these tensions without succumbing to the unsurmountable challenge that practical and individual variations of thought, expectation, and enforcement represent for historical research.

Inside Traders

European merchants could hardly hide their shock at the low prices at which Japanese men, women, and children could be acquired in the late sixteenth and early seventeenth centuries. Florentine merchant Francesco Carletti, who spent eight years circling the globe during in the last decades of the 1500s, wrote of Nagasaki that men could easily find a “girl of fourteen or fifteen years, a virgin and beautiful, for three or four scudos, more or less, according to the span they want to have her at their disposition.”Footnote 18 The same happened to Chinese and Koreans captured overseas and brought to be sold in Japan.Footnote 19 Even in Europe, theologians such as Luís de Molina, whose imaginations were constantly fed by the innumerable missionary reports coming from Asia, were aware of the infamously low prices given for enslaved people in the archipelago.Footnote 20 Japan was a very dynamic market, in which sellers tried to pass along men, women, and children as merchandise as fast as possible.Footnote 21

With the gradual substitution of perpetual forms of medieval bondage for the more dynamic contracts of early modern temporary servitude, a vast number of farmers rushed to urban centres, forming a renovated labour force. By the late sixteenth century, the medieval genin had split: those who possessed land became known as nago—individuals held in bondage, yet owners of their own means of production—while those who held no land nor the means of production became temporary hires, i.e., nenki hōkōnin (persons under nenki hōkō contracts).Footnote 22 Nevertheless, the distinction between genin and nenki hōkōnin was not always clear-cut. In early modern military circles, temporary hires could still be called genin. In this case, the term encompassed middle-rank categories of military servants such as the chūgen, komono, and arashiko, often responsible for tasks such as tending horses and carrying weaponry.Footnote 23 At the same time, there were the so-called buke hōkōnin, servants of military houses which often included individuals of social status subjected to control by people in higher ranks who could also be referred to as genin. Footnote 24 One persistent theory in Japanese scholarship explains that the medieval genin disappeared by the end of the sixteenth century as a result of popular revolts that led to a total reshuffle of the ruling social system in Japan, thus opening the way for the emergence of temporary bondage as the basic form of labour.Footnote 25 By the seventeenth century, the term genin seems to have survived only in military ranks.

Despite this definitional imbroglio, the fact is that both forms of human trafficking and temporary bondage went through profound changes between the late sixteenth and the early seventeenth centuries, prompted not only by historical circumstances but also by legal action. In the 1610s, the second shōgun of the Tokugawa clan, Hidetada, decided to renew anti-human-trafficking policies that had been temporarily halted by the Imjin War (1592–98) and the internal conflicts waged in the wake of his clan's rise to power in the first fifteen years of the seventeenth century. Behind his decision were abusive nenki hōkō contracts, which could hold people in bondage for decades, effectively amounting to perpetual servitude. A pragmatic concern with a lack of labour in the fields also motivated the shogunal policy. After the sieges of Ōsaka (1614–15), a decree (sadame) enacted in October 1616 and a set of thirteen articles (jōjō) published on 27 December 1619 marked the hardening of the Bakufu's stance towards human trafficking.Footnote 26

The first act had an immediate impact on bondage. Contracts of nenki hōkō were capped to a three-year period, and human traffickers attempting to sell people into perpetual bondage could be condemned to capital punishment. The law had determined the annulation of further perpetual sales of people, while guaranteeing to the individual freedom to decide what to do with themselves. Those who had been victims of kidnappings were to be returned to their parents (including people who were not biological parents, but were considered responsible for the child) or, in the case of stolen genin, to their original master (honnushi).Footnote 27 As for the specific case of buke hōkōnin, hired men-at-arms at the service of military houses, the new law reinforced a previous determination from the Bakufu, according to which people of dubious backgrounds could not participate in these arrangements.Footnote 28 At once, the 1616 decree restricted temporary contracts of labour, proscribed human trafficking, and regulated military bondage. Placards were erected throughout the country displaying the new rules. After that, the decree was reenacted twice—in January and December of 1618.Footnote 29

In 1619, the decree was complemented by a set of thirteen articles (or jōjō) that would become the most comprehensive anti-human trafficking law of the Tokugawa shogunate. It introduced seven items regulating and condemning various forms of human trafficking and bondage contracts. Its provisions condemned to death kidnappers who sold their captives, set fines and prison sentences for those intermediating human trafficking, punished parents selling their own children, determined that people kidnapped and sold were to be returned to their original master or set free, prohibited long periods of bondage by contract, and more.Footnote 30 The severe punishments reveal much about how professional human traffickers worked in early modern Japan.

The first form of geninka discussed in the 1619 jōjō was that of the kidnapping of a person (or a genin) followed by a sale.Footnote 31 The law determined that the individual sold was to be returned to his or her original master or parent. In case there was no such person, the victim should be set free. Here, the kidnapper was sentenced to death.Footnote 32 Next, the law discussed the role of active intermediary sellers, specialised in selling away individuals sold to them by a parent in need or a genin owner. The letter of the law reveals there were two types of intermediaries: first, the occasional seller, who sold individuals once or very few times; second, the so-called hitoakinaiyado or hitoshōbaiyado, a professional human trafficker. Here, the punishment depended on the experience of the trafficker. An occasional seller was to be sentenced to one hundred days in prison and pay a hefty fine, which should surpass the criminal's financial resources. In case of default, they were executed. Professional traffickers, however, were immediately sentenced to death.

Those sold directly by those claiming ownership over a genin or by a parent to a buyer, or the case of labourers hired for abusively long terms, were also addressed by the 1619 jōjō. Given the three-year cap set previously to labour contracts, the articles determined that anyone hired for four or more years was to be set free—in such cases, the buyer and seller were to receive an “appropriate fine.” A similar punishment was reserved for people directly selling a person or a child. Furthermore, the articles of 1619 condemned the sale of an individual by his or her original master or parent to a buyer through the use of an intermediary. The text also determined that such go-betweens were to be arrested or receive a hefty fine, depending on the severity of the offence. Lastly, the law also condemned organised schemes of kidnapping and intermediation involving at least two professional traffickers: a kidnapper and a broker. The victim, taken away from their honnushi or parent, was sold by the kidnapper to a specialised intermediary. This fixer would then negotiate the sale with the final buyer. Against such organisations, the shogunal decree decided that both kidnapper and broker were to be condemned to death.Footnote 33

Together, the laws of 1616 and 1619 criminalised the intermediation of human trafficking and perpetual bondage.Footnote 34 However, it is not possible to say that they plainly outlawed geninka. There was no provision setting free people who had previously been subjected to bondage. Also, the effect of this legislation on the enslavement of Japanese and other individuals by Europeans in Japan is questionable, despite claims by Japanese scholars.Footnote 35 The foreign slave trade would be eventually impacted by Tokugawa legislation only in 1621, when Dutch and Portuguese traders were targeted by a Bakufu ordinance against foreigners hiring Japanese servants.Footnote 36 Still, the panorama offered by the Bakufu laws of the late 1610s evidences a high degree of specialisation in Japanese human trafficking networks, where professional vendors and kidnappers depended on the transformation of people into genin and their sales for their own sustenance.Footnote 37 Yet, this legislation leaves aside a number of situations for the geninka of people in Japan, as shown by Jesuit records of the period.

Finding Slavery

The first signs of intervention by Japan Jesuits in the Japanese-Portuguese slave trade date back to the 1560s. By then, missionaries were collecting small amounts from merchants interested in procuring Japanese people in exchange for access to individuals from areas ruled by daimyō with whom they had a good rapport, such as the historical provinces of Bungo and Hizen, in southern Japan. Soon, the priests started issuing licences stipulating the number of years of service under the Portuguese. The practice emulated the Japanese nenki hōkō, which soon caught the attention of Jesuit authorities outside of Japan. By the end of the decade, the superiors had decided that their confréres in the archipelago had the necessary means to properly evaluate the theological and moral consequences and circumstances regarding the issuing of the licenses and their intervention in the trade.Footnote 38

The practice continued at least until 1590, when Japanese ruler Toyotomi Hideyoshi ended a cycle of various prohibitions started in 1587 against kidnappings and human trafficking in Japan. The visitor of the then–Jesuit vice-province of Japan, the Italian priest Alessandro Valignano, a trained lawyer whose actions had deep repercussion in the policies adopted by the various missions of the order in Asia, decided to interfere and halted members of the Society of Jesus from intermediating sales of Japanese individuals to Portuguese merchants.Footnote 39 The measure soon lost its practical effect. During the following decade, the Imjin War brought some twenty- to thirty-thousand war prisoners to the islands, creating a regional boom in human trafficking in which well-known figures of the Japanese Christian community, such as Konishi Yukinaga, baptised Agostinho, played a major role.Footnote 40 At the same time, Jesuits lost control of their monopoly on the transmission of the dogma to Japanese Christians. After their arrival in 1549, the Society of Jesus was the only missionary order in the country until the 1580s, thus enjoying complete control over what points of the Christian doctrine and any positive laws of the Church were transmitted to local believers. This situation allowed them to avoid teachings that could be detrimental either to Japanese Christians or to their own political situation. The arrival of mendicant friars from the Philippines in the 1580s and 1590s—especially Franciscans and Dominicans—meant Jesuits lost their dogmatic monopoly. By then, local Christians could search for alternative council when facing issues related to enslavement, making it more difficult for Jesuits to address this and other moral challenges such as usury, matrimony, idolatry, and the anointment of the sick.Footnote 41 As they recused themselves from meddling in issues of enslavement in Japan, the only option left for the priests of the Society of Jesus was to search for new criteria that could safeguard their own physical survival in an increasingly harsh environment, marked by growing tensions and violence against missionaries, and keep Christians from sinning when procuring locally subjugated bond labour.Footnote 42

The most radical decision of the period came in 1598. Concerns with retaliations against missionaries led the Roman Jesuit curia to instruct the bishop of Japan to enact a letter of excommunication against foreign and local Christians selling Japanese and Koreans in Japan. It was the first time that missionaries made an assertive effort to curtail the trade in people between Europeans and Japanese. However, due to doubts concerning the ability of the bishop of Japan to excommunicate merchants who were not under his jurisdiction, the measure created a jurisdictional dispute between different bishoprics of the Portuguese Padroado in Asia that may have effectively hindered its impact on the trade.Footnote 43 It was against this troubled background that theologians and casuists of the Jesuit College of São Paulo of Goa, the capital of the Portuguese in India, gathered to discuss the problem of Christians in Japan claiming ownership over Japanese individuals.

The minutes of the meeting are undated, but it is clear by the structure of the document, with its short introduction and the issues it raises, that the Jesuits in India were responding to a questionnaire from Japan to Rome sent in 1592.Footnote 44 Discussing matrimony, usury, idolatry, and other topics, the debate deals with slavery in its third section, under the category of cativeiros, or captivities. In highly sophisticated legal texts of the time, the term was used as a cover-all to assess various forms of bondage, while slavery itself (escravidão, in Portuguese) was reserved for specific situations accommodated to the tenets of theology and the ius commune. Footnote 45 Following the scholastic tradition, the debate scrutinises ten legal titles (títulos) introduced as distinct forms of bondage which, as stated by the text, were selected according to the worldview of the Japanese on the subject. This is, effectively, a summary of information obtained from various reports sent from Japan regarding the many forms of geninka. Perusing the chosen categories, it is clear that Jesuit missionaries had established a correspondence between the general idea of Japanese people of lower social strata, the genin, and the Portuguese label cativo, in an attempt to overcome the epistemological tensions between the two sides. The next step was to analyse the conditions of subjugation to each situation against the fundamental legal principles regulating slavery as found in canon law, Roman law, summas, and manuals of casuistry in general. The debate aimed at gathering legal prerequisites that would allow a confessor to tolerate the situation of a bonded person in Japan according to the tenets of slavery as found in the tradition of the ius commune. The forms of geninka analysed in Goa included: sale by father or mother; self-alienation, or voluntary bondage; bondage by birth; bondage by mercy; bondage as a legal punishment; bondage of a daughter or wife who had fled her father or husband to the local lord's manor; bondage in exchange for food during a famine; peonage; conscription by local lord; and, finally, war captivity.

The problem for the Goa Jesuits was that there was no way that these situations could be clearly distinguished as slavery and non-slavery. This was due not to theoretical or legal reasons, but to the lack of authoritative power held by Jesuits in Japan. As argued numerous times by the visitor of the vice-province, Valignano, missionaries could not expect positive outcomes from their reprimands and admonitions because of their limited capacity to alter or influence the courses of action taken by Japanese Christians, particularly powerful individuals, when facing moral doubts.Footnote 46 Because of this disadvantage, there was the need to create grey areas where missionaries could let go of otherwise inadmissible situations. Hence, from the get-go, the debate envisioned three outcomes: forms of Japanese bondage equal to slavery; situations that were not the same as slavery but could be tolerated by the missionaries; and intolerable cases. After all, the purpose of the debate was not to condemn Christians who claimed ownership over Japanese people, but rather to compile general guidelines that would allow Japan Jesuits to overlook legal issues and to tolerate, that is to say, to ignore, illicit courses of action in order to avoid greater illegalities.Footnote 47 Tolerance was a rhetorical device closely related to dissimulation, a legal strategy tacitly approved by canon law that authorised missionaries to conform to local practices while adhering to established theological and legal principles, a much-needed rhetorical device for those attempting to accommodate the Christian dogma to local social dynamics.Footnote 48

The resolution of legal and moral issues in Japan depended on skilful interpretations of natural law. The need to resort to ius naturale came from the position of Japan in early modern Christianity: the archipelago was considered a part of the Christian orb beyond the secular authority of any colonial empire—in the words of the Jesuits themselves, it was a land beyond the jurisdiction of “imperial law,” that is, Roman law. This special circumstance is made clear in their interpretation of Japanese voluntary bondage. Invoking Francisco de Vitoria, the debaters in India highlighted that the acceptance of this form of bondage as voluntary slavery depended on the criteria defended by the manual of Domingo de Soto, the widely established norms of Silvestro Mazzolini's summa, as well as other authors as far as they conformed to the circumstances established by natural law.Footnote 49 Besides these guidelines, Jesuit theologians also employed the determinations of the First Provincial Council of Goa. Celebrated by prelates and vicars of the city in 1567, the synod had established the legal precedents for the identification of servitus in Asia. In its decrees, the council had set five titles of enslavement that could be accepted by ecclesiastical authorities: heredity, just war, voluntary slavery, sale by parent, and punishment according to local, just laws.Footnote 50 This was a much-needed starting point for the Jesuits of São Paulo of Goa to adapt legal and theological authoritative texts from Europe to the realities of Japan.

Some of the forms of geninka analysed were immediately associated with the titles accepted by the synod. For instance, Japanese children born from enslaved mothers were to be readily accepted as enslaved individuals. That followed not only the first title of the provincial council but, foremost, the Roman maxim Partus sequitur ventrem. Footnote 51 Yet, the correspondence with the Japanese form of bondage was not as immediate. According to the Ritsuryō, the perennial historical Japanese code compiled between the seventh and the eight centuries that had served as jurisprudential basis since its promulgation, the ownership over children of genin couples was to be handed over to the person claiming ownership over each parent according to their gender—sons to the owner of the father, daughters to the owner of the mother. In the case of couples of genin and non-genin, the child would assume the status of the parent who had the same gender as them.Footnote 52 This principle was not limited to the case of genin—social status in general was also often transmitted according to the same gender-based rule: sons taking on that of their fathers, daughters of their mothers.Footnote 53 In practice, though, there are not many references to the transmission of the genin status through birth in Jesuit sources referring to everyday practices, which leads to the conclusion that there was quite some leeway in negotiating these decisions. Nevertheless, the authority of the Ritsuryō was always on the minds of early modern Japanese. In 1587, when a group of Japanese visiting Manila was questioned on bondage practices in their country, their response to the fate of genin children replicated the model established by the code.Footnote 54

Jesuit theologians in Goa also dissected the legal conditions behind internal wars waged in Japan and razzias promoted by pirates on the Chinese coast following criteria long established by the doctrine of just war. Analysing the arguments for these attacks, the conclusion was that it would be impossible to define the justice of said wars in Japan, as well as the attacks against Chinese coastal populations by pirates. Hence, prisoners from these conflicts were not considered slaves. However, due to their lack of authority, Jesuits were told to advise local Christians that prisoners were not to be subjected to perpetual but rather to limited-time forms of bondage.Footnote 55

Another group of terms designated individuals exchanged for a price in money. In fact, almost half of the Japanese títulos discussed could be grouped under this heading: children sold by their parents, people who sold themselves, those who were purchased by a merciful individual before being executed, and people who were held to work off a debt. All these instances of geninka could be accepted as slavery according to the European model, but only when a fair price was negotiated by both parties, including when the seller was the person being subjected to bondage. Based on this general acceptance, specific conditions for each case were defined. For example, a person trying to sell a child had to prove they were indeed the parent, and that they were facing extreme necessity—two requisites taken from Domingo de Soto's discussion on the title.Footnote 56 Rescuing people condemned to death could result in tolerable slavery, but the condemnation had to be unjust—a conclusion evocative of the Mediterranean and Atlantic doctrine of rescate. In that case, a Christian could offer a fair ransom and, since no one should be forced to give his or her money for free, the benefactor could hold the rescued person in exchange as their servant, especially when some spiritual good came as a result of such transaction. Finally, the illicit nature of peonage in the islands, in which people were subjected to bondage for very low prices, could also be seen as a tolerable form of slavery. The condition was that missionaries were to advise both parties to reach a fair price for the person held as collateral.Footnote 57

The most challenging point, however, was that of geninka as a form of legal punishment. On this fifth title of the list, the crux of the debate was whether Japanese rulers had the legitimate authority needed to subject someone to geninka as a punishment. Evocative of the acceptance by the 1567 synod of Goa of the authority of local laws when these were deemed just, the Goa theologians listed two cases that could be equated to slavery: when one committed a serious offence (delictos facinorosos y graves) and when a man took part in a revolt that threatened the integrity of the republic. Both were justified with reference to examples from Europe: the punishment of heretics and apostates to the galleys, and the enslavement of Grenadine moriscos by Phillip II.Footnote 58 There remained, however, a problem: Japanese rulers often extended the punishment to the perpetrator's wife and children. The advice given to the confessors in Japan was that they should admonish local warlords and their administrators that even when a man could be punished with geninka, that did not necessarily meant that his wife and children should be subjected to the same fate. The Goa theologians accepted, though, the geninka of wives of those participating in a rebellion, because of legal precedents determining the enslavement of wives and children of priests in Europe. The Jesuits in Goa also referred to a key text by Martín de Azpilcueta, the Relectio capitulo Ita quorundam de Iudaeis. Commissioned by the Portuguese king João III (1502–57, r. 1521–57), the treatise organised arguments in favour of the enslavement of those who aided the “enemies of Christ.”Footnote 59 Citing Antonino of Florence and Silvestro Mazzolini's summas, the resolution reiterated that the enslavement was not ipso facto, that is, men and women could only be considered enslaved when punishing authorities clearly determined so. With these arguments, the theologians accepted the authority of Japanese rulers to enslave criminals. The recognition showed that Japanese laws were being evaluated against not only conditions determined by theology and the ius commune but also historical precedents. Similar argument was made in the discussion of the case of women who had fled their fathers or husbands and sought shelter in the local lord's house. While Japanese custom accepted that these women could be transformed into genin by the lord, the Goa theologians established that they could be considered enslaved only when they had been accused of and condemned for a crime. Otherwise, missionaries should campaign for their liberation in advising Japanese Christians through confession. The same suggestion was repeated in other cases. For instance, those who offered themselves to work in exchange for protection during events like famines and natural disasters were often considered genin in Japanese society, but confessors were to admonish penitents that they should free these genin upon the completion of enough labour to pay for the amount of food, clothing, and shelter provided.Footnote 60

From the ten titles analysed in Goa, the only case of geninka considered unjustifiable was that of Japanese lords who called upon their retainers to relinquish their daughters to serve in their manors. The lack of historical precedents and legal criteria regarding this practice prevented its approval. In the end, the debate compiled a list of conditions necessary to tolerate most instances of geninka. Out of the ten cases put forward by the Japan mission, seven were conditionally accepted as cases of slavery: four cases of commodification, in which the individual could be enslaved in exchange for money, two cases accepted as enslavement by punishment, and one regarding the passing of the bonded status from the mother to the child. Additionally, the subjugation of individuals in exchange for food and shelter and servitude as a result of captivity in war, were to be considered temporary situations of bondage, although they should not be equated to slavery. In the end, missionaries resorted to great sophistication in their arguments out of concern with the religious and legal implications for Christians declaring ownership of enslaved people in Asia and, foremost, with the political and economic consequences missionaries in Japan could face if they decided to condemn these practices. Arguably, the debate revealed how theology and the ius commune were used in casuistical analysis to overcome issues of incommensurability regarding the use of slavery as a legal category in areas where its assessment was considered challenging, such as Japan.

Conclusion

The Jesuit discussion in Goa of the 1590s and the Tokugawa laws of the 1610s were products of fundamentally distinct agendas, which dealt with parts and pieces of various forms of bondage. That said, they offer two unique glimpses of how Japanese traffickers operated, as well as how geninka worked on the ground and related to the practice of colonial enslavement. If the Tokugawa legislation exposed the methods and actors involved in local human trafficking networks, the Jesuit debate shed light on the pervasiveness of the multiple shapes taken by geninka in Japan.

In the aftermath of the debate, the practices adopted in Japan seemingly influenced colonial slave practices in the region. Although it is difficult to trace a direct connection, the insistent calls for the adoption of temporary bondage as a model for slave ownership in East Asia made by the debate in Goa could have influenced the embracing of this model elsewhere. In Manila, for instance, Dominican theologians debated the various circumstances surrounding contracts and periods of labour related to these arrangements, evidencing how it had been already appropriated by the local society in the early seventeenth century.Footnote 61 Hence, while Jesuit analysis of Japanese geninka searched for practices that could be tolerated as slavery, the various forms of colonial slavery in East and Southeast Asia were already changing and adopting these local forms of bondage.

The crossing of both perspectives here sheds light on the wide array of bondage practices in Japan that were adopted by foreigners. Previous scholarship has shown how Dutchmen, Englishmen, Spaniards, and the Portuguese acquired kidnapped individuals, children sold by their parents, war prisoners, people subjected to bondage by crimes committed by their relatives, women who fled their husbands, children given as debt collateral, and various peoples deceived by traffickers in Nagasaki and Hirado.Footnote 62 However, as shown here, Japanese legislation and the 1590s Jesuit debate highlight not only the penetration of the global slave trade in local networks of bondage, but also how foreign slavers depended on the various strategies put in place by local defrauders, professional kidnappers, brokers, and distressed parents.

Unambiguously, the slave trade between Europeans and the Japanese declined following the curbing of internal networks of professional human traffickers in the 1610s. As the Tokugawa laws highlighted the importance of intermediary brokers as fundamental parts in the process, bondage was curtailed not by freeing those subjected to it, but rather by squashing those most important cogs of the trade. If local forms of bondage managed to adapt to the emergence of new forms of hired labour prompted by social changes in the Japanese rural and urban environments, the enslavement of people in Japan by Europeans was not able to adjust as successfully due to increasing legal and political pressure put in place by the regional powers.

As has been made clear in recent studies of slavery in Asia, not all scholars share the same level of enthusiasm for or concern with the definitional question.Footnote 63 That said, the perspective adopted in this paper is intended as a methodological strategy of conceptual provincialisation that addresses said issue from a distinct perspective. By decentring slavery, that is to say, by turning it into a European form of bondage, one can appreciate the encounter of this specific practice with other worldviews as a story of violent transcultural communication. In this context, the European concept of slavery was quite specific and possibly not universally embraced by all colonial players in Asia. That is because, by employing the particular legal notion of servitus, Jesuits worked with a view of the phenomenon that aimed at answering very specific questions. It is obvious that servitus was one among many legal notions used to address the issue of bondage. Despite that, a fully decentred history of slavery as a European practice transported overseas, which analyses how this particular practice changed and developed in tandem with colonialism, necessarily needs to go through discussions about definitions such as the one worked here. The various encounters between European and Asian forms of bondage are just one example among the many found in the complex history of colonialism that ultimately resulted in the paradigmatic enslavement of Black Africans in the colonial world, particularly in the Americas. I only hope that the example presented here instigates similar inquiries elsewhere.

11 Despite introductory remarks, Sousa fails to take these differences into consideration throughout his analysis. Sousa, The Portuguese Slave Trade in Early Modern Japan, 5–8. As for Nelson, he disregards the historicity of the category of slavery in favour of identifying forms of slavery in Japan, opting for a discussion on the means by which one could “descend into slavery, and what rights these slaves had, if any,” in an apparent attempt to transpose conclusions from scholarship on Atlantic slavery to an Asian context. Nelson, “Slavery in Medieval Japan,” 472. Since these issues go beyond the limits of the present paper, I will further explore these in my upcoming book on slavery in early modern Japan.

27 One must keep in mind, however, that the term for kidnapping in Japanese documents does not always refer to the actual physical capture of a person. As Isogai warns, in medieval Japan, one could be accused of the crime of kidnapping a person (hito kōin) if an individual given as collateral for a debt fled or was not handed over to the collector.

31 The original master (honnushi) is a term that is repeated throughout the law together with the term parent. This combination appears to indicate that the original master was not only the person claiming ownership of an individual subjected to bondage but also any legal responsibility for the individual.

32 Sekiguchi calls the kidnapper hitoakibito, although the term is absent from the text of the 1619 law. Sekiguchi, “Edo Bakufu no jinshin baibai kinrei wo megutte,” 242.

33 Despite Sousa's assertion that the kidnapper was known as hitokadoi and the seller as hitoakibito, none of the legislation mentioned here or other early modern laws make use of such terms. Instead, these were more common between the twelfth and the fourteenth centuries, as extensively shown by Isogai. Sousa, The Portuguese Slave Trade in Early Modern Japan, 269; Isogai, Nihon chūsei doreisei ron, 186, 232, 263, 273, 329, 381, 400, and 549. The fact that Japan Jesuits knew Japanese medieval classics such as the Heike Story (Heike monogatari) may explain the inclusion of old-fashioned terms such as these in their 1603–1604 dictionary, from which Sousa draws this vocabulary.

45 Here I disagree with Sousa in his assessment of the use of terms such as moços, mozos, bichos, and jonge by early modern Europeans in Asia to refer to enslaved people. Sousa suggests these terms were used as decoys to avoid illegalities concerning the ownership of enslaved individuals. I agree in part with Alberts, though, who affirms that these terms reflected the childlike treatment dispensed to enslaved people.

46 Valignano's warnings concerning the limited authority enjoyed by the missionaries in Japan are repeated throughout his texts. See, for instance, Jesús López Gay, “Un Documento Inédito del P. G.

José Luis Alvarez-Taladriz (Osaka: private edition, 1998), 497. Writing on the China mission, Erik Zürcher attributes to the weak authority of the missionaries the need for the “method of accommodation” as “the only viable way.” Erik Zürcher, “Jesuit Accommodation and the Chinese Cultural Imperative,” in The Chinese Rites Controversy: Its History and Meaning, ed.

48 Defined as a form of “deliberate looking away” (bewußte Hinwegsehen), dissimulation lacked regulation but enjoyed tacit acceptance by canon lawyers. Joseph Lederer, “Dissimulation,” in Lexikon für Theologie und Kirche III, ed. Michael Buchberger (Freiburg: Verlag Herder, 1986), 426.

50 Particularly relevant is the acceptance of enslavement through punishment according to local laws that could be deemed just. In practice, this decision opened a can of worms, since any merchant could argue that an individual had been fairly enslaved by some local law.

Although the rules of social status transmission were first codified in ancient Japan, these principles involved the transmission of other elements such as material inheritance, profession, and court title, a system that was simplified by the fourteenth century.
