Archaeological view
A 138m keyhole mound at Toriya, Kashihara, with a shield-shaped moat 10–25m wide, dated by Kashihara City to the early 6th century from cylindrical haniwa and Sue ware. A Nara Prefecture walking-guide page instead says it is said to date to the 5th century, so the sources differ.
