Tennozuka Kofun

Tennozuka Kofun is an ancient burial mound near Wakayama with a distinctive keyhole shape made up of a rounded section connected to a rectangular platform. The mound is covered in grass and surrounded by walking paths that allow you to walk around its perimeter and observe its scale.

This burial mound was built during the Kofun period between the 4th and 7th centuries, when Japan's ancient rulers were buried in large earthen mounds. It belongs to the Iwase Senzuka group, a collection of hundreds of tombs from the same era in this region.

The stone chamber within Tennozuka Kofun measures 5.9 meters in height and represents the engineering capabilities of ancient Japanese builders.

The site sits on open ground and is easy to reach on foot, with plenty of space to walk around and observe the mound from different angles. The nearby Kiifudoki-no-oka Museum of History offers more details about burial practices and archaeological finds from this period.

Tennozuka is the largest keyhole-shaped burial mound in Wakayama Prefecture, showcasing the advanced construction methods of the Kofun era. Its carefully designed two-part structure was typical for tombs of high-ranking figures during this period.
