A number of keyhole-shaped burial mounds, called kofun, were constructed on the Miyazaki Plain. Among these kofun, which are unique to Japan, were the Saitobaru Burial Mounds.
Whereas the scenery surrounding the other kofun which scatter the Japanese archipelago have undergone natural changes with the passage of time, the Miyazaki Plain remains much the same as it did in its prosperous times long ago.
In order to preserve the appearance and shape of the kofun, the Miyazaki Plain features almost no surrounding buildings, the only kofun site in Japan to do this.
(The Miyazaki Plain is unique among kofun sites in that it offers a landscape that leaves the original appearance and shape of the kofun intact, with almost no surrounding buildings.)
Explore the kofun from every angle and enjoy a landscape filled with a variety of kofun in a variety of shapes.

Our heritage is a connection to our past: a legacy of our cultural and natural history, and an invaluable source of inspiration to pass on to future generations. The Agency for Cultural Affairs Japan Heritage aims to promote our unique cultural traditions, encourage the use of our national cultural properties, and to revitalize regional economies. Japan's tangible and intangible cultural properties have been preserved through narratives that arose from unique regional histories and traditions. By recognizing these stories as a Japan Heritage, the agency plans to promote these historical legacies and provide comprehensive support so that this heritage may be effectively preserved and maintained.
