History
Hakata Site is an archaeological site in Fukuoka, Japan, preserving a late-Heian-period port facility from the eleventh or early twelfth century. It forms part of the wider Hakata archaeological complex, a multi-period urban and trading area whose remains illuminate Hakata’s long connection with diplomacy and commerce across East Asia.
Prehistoric and Ancient Hakata
Hakata was a port settlement from prehistoric times, and artifacts dating from the late third century have been found in the area. The earliest identified remains include Yayoi-period jar burials, associated with communities that practiced wet-rice agriculture and used metalworking. Later layers preserve evidence of ancient, medieval, early-modern, modern, and contemporary occupation.
Northern Kyushu placed Hakata at the center of Japan’s relations with the Asian continent. The port was connected with the Japanese missions sent to Sui and Tang China, while the surrounding region formed part of the national-defense zone that included Tsukushi Province and northern Kyushu. This area faced conflicts and invasions originating from the Korean Peninsula. Hakata also served as the port of Dazaifu, the major governmental and military center responsible for Kyushu and Japan’s continental relations, until the Kamakura period.
The archaeological complex includes a Nara-period kanga, or government administrative complex, together with port facilities. Imported ceramics from China, Korea, and Southeast Asia, as well as Japanese ceramics and other excavated materials, show the scale and range of Hakata’s international connections.
Medieval Commercial City
Hakata flourished in the medieval period as an autonomous commercial city governed by a council of leading merchants. Its position as a trading port continued after the decline of Korokan in the late eleventh century. Korokan had been an official diplomatic and trading facility for government-directed commerce between Japan and Song China. The later port may also have been connected with the settlement of Chinese merchants known as the Chikuzen Hakata Port Tōbō.
Hakata later became a target during the Mongol invasions of Japan. Its history therefore combined commercial independence with a strategic position on the route between Japan and the Asian continent.
Excavation and Protection
Excavations undertaken before construction of the Fukuoka City Subway Airport Line in 1977 found that ancient remains and artifact-bearing layers were relatively well preserved. Redevelopment at the former Fukuoka Municipal Reizei Elementary School led to further excavation between 2018 and 2022, identifying a stone waterfront structure associated with the late-Heian port.
In 2017, an assemblage of 2,138 particularly important artifacts from the Hakata archaeological complex was collectively designated a National Important Cultural Property. A 961.23-square-meter portion of the site was recommended for national historic-site designation in October 2023 and formally designated as the Hakata Site on February 21, 2024.
Remains
The wider Hakata archaeological complex lies mainly northwest of JR Hakata Station on a belt of sand dunes between the Naka and Mikasa rivers. Its known archaeological area extends about 1.6 kilometers from north to south and 0.8 kilometers from east to west, with Taihaku Street as its central axis. Remains from successive periods are superimposed, creating a layered archaeological record that includes Yayoi burials, the Nara-period administrative complex, port facilities, and medieval urban remains.
Late-Heian Port Structure
The Hakata Site itself consists of a stone revetment, a retaining structure that protected the edge of land or water, regarded as a late-Heian port facility. It was built along the bank of a back marsh, a low-lying wetland behind a riverbank or shoreline, near the mouths of the Naka and Mikasa rivers before they joined and flowed into Hakata Bay.
The revetment lay between the eleventh-century shoreline and the edge of the sand dune. Its stonework was approximately 1.2 to 1.6 meters wide and about 60 centimeters high, extending roughly 70 meters from north to south. Sulfur particles found in the surrounding sediment are relevant to the port’s trading history because sulfur was an important Japanese export to Song China during this period.
Excavated Materials
Excavations across the complex have produced ceramics, earthenware, wooden objects, metal products, and stone products. The ceramics include imports from China, Korea, and Southeast Asia alongside Japanese examples. Together, these materials provide physical evidence of the goods circulating through Hakata and of the port’s role in international trade.
