Guide
The Shinbara-Nuyama Kofun Cluster is a nationally designated historic site located in Fukuchi City, Fukuoka Prefecture. This site is characterized by a dense concentration of burial mounds (kofun) constructed between the 5th and 6th centuries. The cluster features a diverse range of shapes, including keyhole-shaped (zenpokoen-fun), square-shaped (hofun), and circular (enfun) mounds. This area boasts the highest density of kofun within the Tsuyazaki area, offering a rich variety in both scale and form. Because the mounds are preserved alongside the natural terrain, they serve as a vital historical record of ancient social structures and regional exchange.
The construction of these mounds dates back to the 5th and 6th centuries. For example, Mound No. 22 is believed to be one of the chief's tombs for the Munakata clan during the 5th century. Historically, this region was an inlet, and it is thought that a port once existed here to facilitate maritime trade and diplomacy. The arrangement and shape of the mounds reflect the social hierarchy of the time and the relationship between the local leadership and the Yamato court. Since 1975, various archaeological excavations have been conducted to preserve and study these sites during land development and infrastructure projects.
The cluster contains several significant mounds, each with distinct characteristics:
As this is an outdoor archaeological site, there are no specific opening hours or seasonal restrictions. However, we recommend visiting during daylight hours to clearly observe the shapes and contours of the mounds. The site is accessible throughout the year.
This site is ideal for travelers interested in observing the evolution of ancient Japanese burial architecture. By comparing the different shapes—keyhole, square, and circular—visitors can gain a deeper understanding of ancient engineering and social structures. The way the mounds integrate with the natural landscape offers a unique perspective on how ancient people utilized the terrain.
The area surrounding the cluster has a unique geography; it was once an inlet before land reclamation projects in the Edo period. Geological studies suggest the coastline was much closer to this site 5,000 years ago, providing a fascinating look at the ancient maritime environment of Fukuoka.
