Era
The closing of the doors: Shimabara, the final expulsion of the Portuguese, and the narrow channels of contact that survived.

The end came quickly. The artificial island of Dejima was built in Nagasaki harbour in 1636 to confine the Portuguese; a year later the Shimabara Rebellion — a peasant rising under Christian banners on the Amakusa coast — confirmed the bakufu’s darkest suspicions at the cost of some thirty-seven thousand lives. In 1639 the black ships were banned from Japan forever.
When Macau sent an embassy in 1640 to plead for the trade’s restoration, sixty-one of its members were executed at Nagasaki. The Dutch, useful and religiously discreet, were moved onto vacant Dejima in 1641 — the single narrow channel through which Europe and Japan would speak for the next two centuries. The remaining Japanese Christians vanished into the hidden church, and a century of exchange closed with the doors bolted from within.
The Shimabara Rebellion of 1637–38 sealed the fate of European presence in Japan. This article examines the cascade of edicts that led to two centuries of isolation, and why the Tokugawa saw foreign contact as an existential threat.
In the winter of 1637, 37,000 starving peasants, many of them crypto-Christians led by a teenage prophet, fortified a ruined castle and defied the largest army the Tokugawa shogunate had ever assembled. Their annihilation ended a century of European contact.
The Tokugawa shogunate locked the country shut and kept just a few windows open. What happened next, two centuries of domestic revolution in agriculture, commerce, culture, and science, would ensure that when the doors were finally forced open, the nation behind them was anything but medieval.
In the summer of 1640, 74 unarmed men sailed from Macau into a harbor they had been explicitly forbidden to enter. 61 of them would lose their heads. The 13 who survived were meant to send a message.
A bloodless coup in Lisbon, a twenty-eight-year war, and the desperate alliances that saved a kingdom, at the cost of its empire.
Seven years after the expulsion, four years after sixty-one men lost their heads, Portugal sent two galleons back to Nagasaki, armed with a new king, a new argument, and an old refusal to take no for an answer.
