Located in Tenri, Nara Prefecture, Japan, the Isonokami Ōtsuka Kofun is a keyhole-shaped burial mound (zenpō-kōen-fun) dating to around 600 CE. This funerary monument exemplifies the distinctive architectural form that characterized later kofun construction, with its characteristic rounded rear section and rectangular forward platform. Built during the final centuries of the kofun era, it represents the monumental burial practices of early Japanese civilization.
