Kōmyōsan Kofun, Ancient burial mound in Shizuoka Prefecture, Japan
The Kōmyōsan Kofun consists of a square front section connected to a circular rear portion, forming a keyhole shape when observed from above.
Built during the Kofun period between the 3rd and 7th centuries, this megalithic tomb represents the emergence of centralized power in ancient Japan.
Archaeological excavations at Kōmyōsan Kofun revealed burial artifacts including bronze mirrors, pottery, and weapons that indicate trade connections with mainland Asia.
Visitors can access the site by following designated pathways that lead to observation points offering views of the burial mound structure.
The construction required precise engineering to create the distinctive keyhole shape using local earth materials and stone arrangements.
