Jōurugami Kofun, Ancient burial mound in Sakai City, Japan
Jōurugami Kofun is a keyhole-shaped burial mound in Sakai that dates back to ancient Japan. The structure stretches over 400 meters in length and is protected by three concentric water channels surrounding its earthen core.
Built in the 5th century, this site emerged during the Yamato period when rulers constructed massive burial complexes for their elite. The practice reflected the social hierarchies and architectural ambitions of that era.
This burial site demonstrates how ancient Japanese rulers were honored through monumental earth constructions. The multiple tiers and surrounding water channels were visible signs of the deceased's power and status in their time.
Direct entry is not permitted, but you can view the monument from the Sakai City Hall observation deck. The elevated vantage point gives you a clear perspective of the entire structure's distinctive outline.
Hidden inside the burial chamber lies a stone sarcophagus surrounded by flat stones and filled with precious items like bronze mirrors and jade ornaments. These objects reveal the wealth and wide trade connections of the ruler entombed there.
