In this video, we uncover the mystery behind the Kofun keyhole tombs, exploring their origins, their surprising global similarities, and the theories suggesting they may have been ritual gateways, astronomical markers, or even symbolic portals to the divine realm. Why does the Japanese government restrict access to many of these sites? And why do these tombs align with ancient myths about heavenly beings descending to Earth?
