Iwaya Kofun is a zenpō-kōen-fun (keyhole-shaped tumulus) located in Yonago, Japan, dating to around 600 CE. This type of kofun—a monumental earthen mound characteristic of ancient Japan—features the distinctive keyhole form with a circular burial chamber connected to a rectangular front section, a design convention of the Kofun period representing the apex of funerary architecture in early Japan.
