Inaridai No. 1 Kofun

The circular burial structure measures 28 meters in diameter and contains two wooden coffins positioned within the earthen mound construction.

Archaeological excavations in the fifth-century tomb revealed military items, including arrowheads, metal body armor with rivets, and an inscribed iron sword.

The inscribed iron sword bears silver text expressing respect to the king, indicating a structured social hierarchy between rulers and regional chiefs.

Visitors can examine archaeological findings from the burial mound at local museums and read information signs explaining the site's historical context.

Two separate wooden coffins within the mound contained remains of individuals from the warrior class nobility, along with ceremonial weapons and armor.
