Latest / The History of Portugal: The Small Nation That Built a Global Empire — Fexingo History / The Portuguese in Japan: Silk, Guns, and the Hidden Christians
Transcript
- Lucas: We’ve spent a lot of time talking about the Estado da Índia, the fortified ports from Goa to Malacca, and the naval supremacy that let Portugal dominate the Indian Ocean. But there’s another chapter of their global story that feels almost like a different universe entirely: Japan. Luna: I remember you mentioning Nagasaki earlier, but I didn't realize how deep the connection went. Lucas: It was far deeper than anyone expected at the time. When the Portuguese first arrived in the mid-1500s, Japan wasn't a unified country yet. It was in the Sengoku period, a century of civil war where local warlords, or daimyo, were constantly fighting for dominance. That chaos is exactly what made them so open to foreign influence. Luna: So they weren't looking for conquest, just trade partners? Lucas: Exactly. And the Portuguese offered something Japan desperately needed: military technology. In 1543, Portuguese traders were blown off course and landed on Tanegashima island, south of Kyushu. They carried two matchlock arquebuses, and the local lord was so fascinated he commissioned his craftsmen to reverse-engineer them immediately. Luna: That must have changed everything for the samurai. Lucas: It revolutionized Japanese warfare. Within a year, Japanese artisans were producing thousands of these guns, known as Tanegashima. This gave certain daimyo a massive advantage over those who relied solely on bows and swords. It shifted the balance of power rapidly, fueling the already intense conflicts of the era. Luna: And this is when the missionaries came in? Lucas: Yes, shortly after. In 1549, the Jesuit priest Francis Xavier arrived in Kagoshima. He was a fascinating figure, very adaptable. He learned Japanese, studied Buddhist texts to find common ground, and even dressed partly like a monk to gain respect. He baptized around a hundred people in his first few months, mostly in the southern regions. Luna: Did the Japanese see Christianity as just another foreign religion? Lucas: Initially, yes. Many viewed it through the lens of Buddhism or Confucianism. But what really cemented Christianity's place was political. One of the most powerful daimyo, Oda Nobunaga, saw the Christians as a useful tool against the powerful Buddhist monastic armies that often opposed him. He granted them protection and land. Luna: Oh interesting, using religion as a political shield. Lucas: Precisely. Nobunaga tolerated the missionaries because they came with traders, and traders brought silver and goods. He also distrusted the Buddhist temples, which had their own private armies. By backing the Christians, he weakened his enemies while boosting his economy. It was a pragmatic alliance born of war. Luna: So Christianity spread quickly under his protection. Lucas: It did. By the time Nobunaga died, there were hundreds of thousands of converts. His successor, Toyotomi Hideyoshi, initially continued this tolerance, but his attitude shifted as he consolidated power and feared foreign colonial ambitions, especially after seeing what Spain was doing in the Philippines. Luna: That sounds like the turning point for the Portuguese influence. Lucas: It was. In 1587, Hideyoshi issued the Bateren Fugu Rei, the Edict Expelling the Missionaries. He banned the Jesuits and other priests from entering Japan, though he didn't immediately kill all the converts. The focus was on removing the perceived threat of European colonialism disguised as religious conversion. Luna: But the trade probably kept going anyway. Lucas: Correct. Hideyoshi hated the priests but loved the money. The Portuguese trade ships, bringing silk from China and spices from Asia, were too valuable to stop completely. So, a strange compromise emerged: the missionaries could stay out of sight, but the trade continued, centered around the newly established port of Nagasaki. Luna: Wait, did Portugal actually control Nagasaki? Lucas: Not directly, but they managed it. In 1580, the Daimyo of Nagasaki, Omura Sumitada, ceded the city to the Jesuits as a donation. It became an autonomous city governed by the Misericórdia, a Portuguese charitable brotherhood. For a short time, Nagasaki was essentially a Portuguese enclave within Japan, complete with its own laws and architecture. Luna: That sounds incredibly unique for East Asia at the time. Lucas: It was. The Casa de Nagasaki handled the logistics, warehousing, and distribution of goods. It was a hub of cultural exchange where Japanese artists adopted European techniques like perspective painting, and Portuguese introduced new foods and words into the Japanese language. You can still find traces of this Nanban culture today. Luna: I'd love to hear more about how this eventually ended. Lucas: Well, after Hideyoshi, the Tokugawa Shogunate took over. Tokugawa Ieyasu was more cautious and eventually aligned with the Dutch and English, who were less interested in conversion and more focused purely on profit. The Shogunate began a systematic purge of Christianity, viewing it as a destabilizing force loyal to a foreign pope rather than the Shogun. Luna: So the Portuguese lost their privileged position. Lucas: They did. By the early 1600s, the persecution intensified. The Shimabara Rebellion in 1637, led largely by persecuted Christians, convinced the Shogunate that Christianity was a direct threat to state stability. After crushing the rebellion, they expelled the Portuguese entirely and initiated the Sakoku policy, closing Japan to almost all foreign contact. Luna: It’s amazing how fast that closed down. Lucas: It was swift and total. The Portuguese were replaced by the Dutch, who were confined to a tiny artificial island in Nagasaki harbor. But the legacy remained. Thousands of Japanese Christians went underground, becoming Kakure Kirishitan, hiding their faith for centuries until they were rediscovered in the 19th century. Luna: Hidden Christians? That’s a powerful image. Lucas: It is. These communities blended Catholic rituals with Buddhist symbols to avoid detection, creating a unique syncretic faith. They preserved the core of Christianity in secret, maintaining their identity despite decades of brutal persecution. It shows the resilience of both the faith and the people who held onto it. Luna: I never realized the Portuguese impact was so personal and lasting. Lucas: It’s one of those historical threads that connects the dots between Europe, Asia, and the Americas in ways we often overlook. From the matchlocks on Tanegashima to the hidden prayers in rural villages, the Portuguese Empire wasn't just about forts and fleets; it was about human connections, however complicated. Luna: Those connections definitely shaped the modern world. Lucas: Absolutely. And speaking of keeping these stories alive, if you've been stepping into history with us episode by episode, you know how much work goes into digging up these details. If today was actually useful to you, the way these stay ad-free is listener support — buy me a coffee dot com slash fexingo. Luna: Yeah, it really helps keep the research going for these deep dives. Lucas: Thanks for supporting us. Now, back to Japan, because the end of the Portuguese era didn't mean the end of the exchange. Luna: What happened to the Japanese who had converted? Lucas: Many were executed, but others fled to Southeast Asia or went underground in remote islands like Goto and Amakusa. The latter group, the Kakure Kirishitan, survived in secrecy for over 250 years. They kept their faith alive by adapting it, using statues of Kannon the Bodhisattva as masks for the Virgin Mary, for example. Luna: That kind of adaptation is remarkable survival. Lucas: It is. When they were finally revealed to the outside world in 1865, Western sailors were shocked to find intact Catholic communities in Japan. The Vatican had thought they were extinct. Their rediscovery was a huge diplomatic event, marking the beginning of Japan's re-engagement with the West after centuries of isolation. Luna: It’s a full circle moment from their initial arrival. Lucas: Exactly. From the shock of the matchlock in 1543 to the shock of the surviving Christians in 1865, the Portuguese footprint in Japan was brief but incredibly intense. It reminds us that empires aren't just built on land, but on ideas and technologies that travel faster than borders. Luna: A tiny nation leaving such a big mark. Lucas: Indeed. And it makes you wonder what other hidden histories are waiting to be found in the spaces between major empires. Maybe next time we'll look at how that trade network influenced things beyond just guns and faith. Luna: I'm definitely curious to see where that leads.
