Archaeological view
The mound is badly eroded and its form is unknown, possibly square or round; Kashihara City gives its size as around 30m and its height as about 8m. Kashihara City considers it to have been built in the 7th century, judging from the form of its chamber. The Nara Prefectural Library and Information Center's "Nara in 2010" guide notes that researchers have also named this mound among the candidates for Empress Saimei's tomb, separate from the IHA designation.
