A Complete Timeline of Portuguese-Japanese Exchange, 1543–1650

From the accidental landing on Tanegashima to the final expulsion after Shimabara, a comprehensive chronology of the key events, treaties, and turning points that defined a century of contact between two civilizations at opposite ends of the known world.

Tanegashima, 1543: First Contact and the Gun that Changed Japan

When Portuguese merchants introduced the matchlock arquebus in 1543, they unknowingly handed the warring daimyō a tool that would reshape Japanese warfare. Within decades, Japan possessed more firearms than any European nation.

The Keichō Embassy: A Samurai in the Court of the Spanish King

In 1613, a one-eyed northern warlord sent his retainer across three oceans to negotiate with Philip III of Spain and Pope Paul V. The mission spanned seven years, three continents, and ended in failure, martyrdom, and a galleon sold off as a Spanish warship.

Southern Barbarian Chicken: The Improbable History of Chicken Nanban

A 16th-century Portuguese fish-pickling technique, four centuries of dormancy, a postwar restaurant kitchen running out of ideas for leftover chicken breast, and a tartar sauce argument that split a city in two. This is how Japan got its favorite fried chicken.

A Title from Siam: Yamada Nagamasa and the Japanese Quarter of Ayutthaya, 1621–1630

A gift of sharkskin and gunpowder that left two Tokugawa councillors asking who had sent it, a votive ship lost to a shrine fire, and a governorship that was a promotion and a dismissal in the same document. A Japanese merchant became one of Siam's most powerful men, and a 1942 schoolbook turned his career into a national glory it never actually claimed.

The Ground They Kept: Urakami Cathedral, Persecution and Reconstruction, 1865–2025

The parish that had once been forced to prove its abandonment of Christianity by trampling sacred images bought that very ground, spent 30 years raising a red-brick cathedral on it, and watched an atomic bomb tear the building down 20 years later. What followed was not a debate over whether Urakami mattered, but over whether a ruin or a working church proved it best.

A Witness from Rome: Thomas Araki and Japan’s Christian Persecution, 1619–1640s

A Japanese priest carried a Latin-dedicated book from Nagasaki to Rome, then apostatized at Ōmura in 1619 and spent a quarter century helping the magistracy that hunted down the missionaries who had trained him. He signed that Roman dedication presbyter, priest, and that single Latin word is nearly the only thing about his life that historians agree on.
