Gobyoyama Tumulus: Anchoring the center of the Mozu Tumulus Cluster

Gobyoyama Tumulus consists of a keyhole-shaped mound 186 meters in length. Its name alludes to the fact that it was thought to be the tomb of the emperor Ojin, and it is marked as such on some Edo-period drawings. Excavations in the vicinity of the tumulus have uncovered the remains of a double moat. It is thought to have been constructed during the middle or late fifth century, and the site is surrounded by several smaller baicho tumuli (smaller mounds located in close proximity to major tumuli).
Gobyoyama Tumulus has served as the inner temple of nearby Mozu Hachimangu Shrine, which enshrines the emperor Ojin, and a Buddhist-style stone lantern dating from the Edo period can be seen on the east side of the top of the structure. The site also hosts invaluable natural plant life including camellia trees and massive camphor trees.
