Atagoyama Kofun (Mito)

The Atagoyama Kofun is a keyhole-shaped tumulus (kofun) located in Mito, Ibaraki Prefecture, Japan. It is a significant archaeological site, belonging to the middle Kofun period (around the 5th century AD). The kofun is believed to have been constructed for a powerful local ruler or chieftain of the area during that era.

Excavations at the Atagoyama Kofun have yielded various artifacts, including haniwa (terracotta clay figures), weapons, and ornaments, providing valuable insights into the burial practices and social structures of the time. The haniwa found here are particularly notable and contribute to the understanding of regional variations in haniwa styles.

The Atagoyama Kofun's size and shape are typical of keyhole-shaped kofun constructed during the middle Kofun period, demonstrating the influence of Yamato court burial traditions spreading throughout the regions. The site is maintained and preserved as a historical landmark, open to the public for educational and research purposes. Its study continues to contribute to a broader understanding of the Kofun period in Japanese history, particularly the development of local power centers and their relationship with the central Yamato court.
