Nobono Ōtsuka Kofun is a zenpō-kōen-fun (keyhole-shaped burial mound) located in Kameyama, Mie Prefecture, Japan, dating to around 400 CE. This type of kofun, characteristic of Japan's Kofun period, features the distinctive keyhole form—a circular mound attached to a rectangular platform—that served as an imperial or elite mausoleum. The site represents the monumental funerary architecture typical of early fifth-century Japan.
