児屋根塚古墳

The Koyane-zuka Kofun is a large earthen mound located in Miyazaki Prefecture and belongs to the Chausubaru group of burial sites. The structure displays the characteristic form of these ancient burial mounds with internal chamber systems.

The mound dates from the late 4th century and was built during a period when regional leaders demonstrated their power through monumental tomb construction. This building practice was typical of the Kofun period in Japan.

The tomb design reflects early Japanese burial practices, incorporating stone chambers and ceremonial spaces that served both memorial and political functions.

The site is located in a rural area and is most easily reached by vehicle. The surroundings are open and relatively flat, making exploration of the mound straightforward.

Archaeological finds at the site suggest connections between local elites and communities on the Korean Peninsula. These objects reveal a network of exchange and contact that existed during ancient times.
