A joint team of Japanese and Chinese marine archaeologists has located the wreck of a mid-16th-century Wokou pirate ship in the deep waters off Kyushu. The vessel, preserved in an anoxic silt pocket, has yielded a trove of weaponry including rare Ming-style swivel cannons and several varieties of Japanese katanas, highlighting the multi-ethnic nature of the maritime raiders who once dominated the East China Sea.
Initial surveys of the site suggest the ship was part of a larger fleet that operated during the height of the Sengoku period. The discovery of private merchant seals alongside the weaponry suggests that the crew engaged in both legitimate trade and illicit raiding, providing a rare physical record of the complex geopolitical and economic tensions that defined 16th-century Asian maritime history.
