 His name might have been regularized centuries after the lifetime ascribed to Itoku, possibly during the time in which legends about the origins of the Yamato dynasty were compiled as the chronicles known today as the "Kojiki".While the actual site of Itoku's grave is not known, the Emperor is traditionally venerated at a memorial Shinto shrine ("misasagi") in Kashihara.The Imperial Household Agency designates this location as Itoku's mausoleum.
