Tsukuriyama Ancient Burial Mound

Tsukuriyama Ancient Burial Mound is a large earthen structure shaped like a keyhole, consisting of a rectangular section linked to a circular mound. The construction demonstrates the sophisticated building methods of the period and functioned as a royal or elite burial site.

This structure was built during the first half of the 5th century when the Kofun period was at its height. The mound represents how societies of that era honored their deceased and invested in monumental construction.

The presence of Aragami Shrine at the summit of the burial mound connects the ancient burial practices with subsequent religious developments in Japanese society.

The site is generally accessible and has an information center with resources to help visitors understand its significance. Wear sturdy shoes as walking up the mound can be steep in places.

Researchers use modern surveying technology to analyze how ancient Chinese measurement systems influenced the construction design. This reveals how external knowledge shaped building practices of the period.
