1542

A storm-blown Chinese junk carrying three Portuguese adventurers drifted onto the Japanese island of Tanegashima. They stepped ashore holding matchlock arquebuses. Within months Japanese smiths were reproducing the weapons, and a trade in silk, silver, and guns had opened between Nagasaki and Macao. Japanese adoption of Portuguese firearms was one of history's fastest military technology transfers, transforming island warfare within a generation.
