Tosaminato, Archaeological seaport in Goshogawara, Japan
The remains of Tosaminato cover 55 hectares along the coast, featuring earthen walls and archaeological evidence of maritime activities from ancient times.
The port settlement operated from the Heian to Muromachi period under the Ando clan, serving as a major trading point with Korea and mainland Asia.
Excavations at Tosaminato revealed Chinese ceramics and Kyoto-style tiles, indicating strong commercial connections with different regions during the 15th century.
The archaeological site opens for guided tours between July and October, with reservations required through the Goshogawara City tourism department.
Lake Jusan, which now separates Tosaminato from the Sea of Japan, was originally an inlet that formed the natural harbor of this trading port.
