Teppōyama Kofun, Keyhole-shaped burial mound in Gyoda, Japan.
The Teppōyama burial mound features a distinctive keyhole layout with a circular rear section measuring 67 meters in diameter and 11.7 meters in height.
Construction of this ancient tomb dates to the 6th century AD, during a period of significant political development in the Kanto region of Japan.
The tomb structure, part of the Sakitama Kofun Cluster, demonstrates the burial practices of high-ranking individuals during Japan's Kofun period.
