- Lucas: So we've talked a lot about the Nanban trade — how the Portuguese arrived in Japan in the 1540s and built a lucrative business in silver and silk, with Jesuit missionaries riding the coattails. But by the 1630s, the shine was wearing off. Luna: Things started to sour? Lucas: Yeah, under Tokugawa Iemitsu, the third shogun, the regime got deeply suspicious of Christianity. They saw it as a fifth column — a foreign religion that demanded loyalty to a pope overseas. Persecution began in earnest: executions, forced recantations, the whole machinery of suppression. Lucas: But the real explosion came in 1637, in the Shimabara domain on Kyushu. This was a region with a heavy Christian population, partly because the local daimyo, Arima Harunobu, had been a Christian convert. But after his clan was replaced, the new lords, the Matsukura family, imposed crushing taxes and brutal rule. Luna: So it was economic as well as religious? Lucas: Exactly. The peasants were starving, and the samurai who had lost their masters were angry. And then a charismatic teenage boy emerged — Amakusa Shiro. He was said to be a miracle worker, and he quickly became the figurehead of a rebellion that mixed Christian millenarianism with plain old righteous fury. Lucas: They gathered thousands — about 30,000 people, including women and children — and they fortified the ruins of Hara Castle, an old fortification overlooking the sea. And they dug in. Luna: Against the entire shogunate army? Lucas: Pretty much. The shogun sent a massive force, eventually over 120,000 men under the command of Itakura Shigemasa and later Matsudaira Nobutsuna. But the rebels held out for months. They had weapons, food, and a conviction that God would deliver them. Lucas: The siege of Hara Castle became a standoff. The shogun's forces tried assault after assault, but the defenses held. And here's where Portugal comes in — because the shogunate suspected Portuguese missionaries had instigated the rebellion. They even demanded that the Portuguese ships in Nagasaki harbor help them. Luna: Did the Portuguese help? Lucas: No — they refused. But the Dutch didn't. The VOC — the Dutch East India Company — saw an opportunity. They had a ship, the de Ryp, anchored nearby, and they offered cannons and gunpowder to the shogunate. The Dutch even bombarded Hara Castle from the sea. Luna: So the Dutch literally helped crush the rebellion to get rid of their Portuguese rivals? Lucas: Exactly. It was a brutal piece of realpolitik. And it worked. In April 1638, after a final assault, Hara Castle fell. Nearly all the rebels were killed, including Amakusa Shiro — his head was displayed in Nagasaki. Lucas: The shogunate was convinced that Christianity was a threat, and they blamed the Portuguese. In 1639, they expelled all Portuguese permanently. Only the Dutch were allowed to stay, but they were confined to the tiny artificial island of Dejima in Nagasaki Bay. Luna: That really was the end of the Portuguese era in Japan. Lucas: Yeah. It's one of those moments where you realize how much hinges on a single event. If the Dutch hadn't helped, maybe the rebellion would have dragged on, maybe the shogunate would have been less drastic. But as it was, Portugal lost its most profitable Asian trade partner. Lucas: Honestly, if this episode was worth a coffee to you, that's the link — buy me a coffee dot com slash fexingo. Just a small thing that keeps this ad-free, you know? Luna: Yeah, it really adds up. And it means we can keep digging into these stories without interruption. Lucas: Right. So after the expulsion, Portugal tried to get back in — they sent embassies, but the shogunate wouldn't even let them land. Japan was now closed. Sakoku. The only window to the outside world was Dejima, where the Dutch were basically treated as prisoners. Luna: And what happened to the Christian communities that survived? Lucas: They went underground — the Kakure Kirishitan, hidden Christians. They practiced their faith in secret for over two centuries, often with a Japanese veneer. When Japan opened up again in the 1850s, many of them emerged, still clinging to rosaries they'd passed down through generations. Luna: That's incredible. A hidden faith surviving all that time. Lucas: It is. And it's a testament to how deep the Portuguese missionary roots had grown in those first decades. But the empire never recovered this loss. Japan became a Dutch-Japanese world, and Portugal's Asian empire shifted focus to Macau, Timor, and the Estado da Índia. Lucas: There's a certain irony: the Portuguese who had brought Christianity to Japan saw it turned against them. And the Dutch, who had fought the Portuguese in Asia for decades, ended up as the sole European presence in Japan — all because they were willing to fire cannon at a castle full of Christians. Luna: History really does have sharp edges. Lucas: It does. And that's the story of how Portugal lost Japan — a rebellion, a siege, and a Dutch betrayal that closed the door forever.
