Mikumo-Iwara Site

Mikumo-Iwara Site is an archaeological excavation in a river valley containing multiple dig areas spread across the landscape where researchers uncover ancient Japanese artifacts and building structures. The remains found here span different periods of early Japanese history, offering insights into how people lived in this region long ago.

This site dates to the Yayoi period and was part of the Ito Kingdom, which appears in Chinese records from the 300s. That mention in foreign documents suggests this kingdom held enough importance to be noted by outside observers at that time.

Excavations uncovered Chinese bronze mirrors, weapons, and decorative objects showing that ancient residents exchanged goods with mainland Asia. Visitors can see these items displayed nearby and understand how people here were connected to distant trade routes.

The nearby Ito Historical Museum provides information and displays many objects from the excavations. Visitors should plan to explore both the dig site itself and the museum exhibits to get a complete picture of what has been discovered here.

Two adjacent tombs containing bronze mirrors suggest the burial places of two important people, possibly a ruler and their spouse. This paired burial of high-status individuals is rare and reveals details about how burials were arranged and how power was organized in this ancient society.
