Ishibutai Kofun contains Japan’s largest known megalithic stone burial chamber, built in the late sixth century and believed to be Soga no Umako’s tomb. Its 14 massive granite stones include ceiling stones weighing about 60 and 77 metric tons; more than 2,000 tons came from a quarry on Mount Takamatsuzuka roughly 2 km (1.2 miles) away. The video argues that the covering mound was deliberately removed as retaliation after the Soga family was condemned, but its 20-year timing is inconsistent with Umako’s heirs being condemned in 587–588, only one or two years after his death in 586. 🏛️
