Myōkensan Kofun

The Myōkensan Kofun presents a keyhole-shaped design with two distinct burial chambers, measuring 56 meters in length and constructed on granite bedrock.

Archaeological excavations from 1990 to 1993 revealed numerous artifacts, including bronze mirrors, iron weapons, and thousands of earthenware fragments from the early Kofun period.

The burial chambers contain specific arrangements of ceremonial objects, reflecting the social hierarchy and funeral practices of ancient Japanese civilization.

Visitors can access the site by taking a 25-minute walk from JR Shikoku Yosan Line Onishi Station to explore the preserved burial mound.

The mound contains two separate chambers: one measuring 10.8 by 5.6 meters and another holding a complete Chinese bronze mirror of 11.3 centimeters diameter.
