The Hiiragetuka Kofun is a zenpō-kōen-fun (keyhole-shaped burial mound) located in Asaka, Japan. This ancient funerary monument exemplifies the distinctive architectural form that characterized Japanese burial practices during the kofun period, with its characteristic combination of a circular rear section and a rectangular front section that together create the iconic keyhole silhouette when viewed from above.
