Shimanoyama Kofun

Shimanoyama Kofun is an ancient burial mound with a distinctive keyhole shape, comprising a circular rear section and a rectangular front portion. A moat surrounds the entire structure, which contains burial chambers and chambers for ceremonial objects from the era.

Built between 250 and 538 AD during the Kofun Period, this mound reflects burial practices of ancient Japanese rulers. Its construction reveals how power and social rank were expressed through monumental architecture.

The keyhole shape itself was a symbol of status in ancient Japan, marking where important regional leaders were laid to rest. This design choice reflected how society organized itself around powerful figures.

Walking paths circle the mound and allow visitors to observe its full shape and proportions from different viewpoints. Information boards at key locations explain the archaeological significance and design elements.

The arrangement of stones and the encircling moat have remained virtually unchanged for over 1.500 years. This preservation allows visitors to see how the site actually looked when it was first constructed.
