Ishibutai Kofun
Exposed megalithic burial chamber in Asuka, Nara Prefecture, Japan, the largest such megalithic structure in the country. Thirty granite blocks from Mount Tonomine, 3 km away, form a platform, a passage and a chamber roofed by two capstones; the largest weigh up to 75 tonnes. The earth mound is gone, which one reading attributes to a posthumous punishment of the Soga clan. It is inferred to be the tomb of Soga no Umako, who died in 626. Named 'stone stage' by 1853.
