It is identified as the oldest and largest burial mound within the Shidami Kofun cluster.
The burial mound was constructed using a specific design known as a circular kofun (enpun), measuring approximately 45 meters in diameter.
Archaeologists discovered that the mound was originally decorated with a vast array of cylindrical haniwa earthenware.
The reconstruction project involved using georadar and traditional archaeological stratigraphic analysis to ensure historical accuracy.
Its location in a basin near the Shonai River provided significant strategic control over ancient trade routes.
Shidami Otsuka Kofun is a reconstructed 4th-century circular burial mound located within the Shidami Kofun Group, a designated National Historic Site in Nagoya. The site features a restored moat and a stone-covered exterior designed to reflect the original appearance of the tomb during the Kofun period. Visitors can walk atop the mound, which provides an elevated view of the surrounding Shidami Kofun Museum grounds. Archeological excavations at the site uncovered haniwa clay vessels and stone tools, offering insight into the burial customs of regional rulers. It serves as a central point in the larger Shidami History Village, which integrates multiple nearby tumuli into a walking trail. The site is maintained as an open-air historical park.
