Archaeological view
Square mound (~18m per side) in Anamushi, Kashiba City. Late 7th century. Contains a nationally historic yokoguchi-shiki sekkaku (side-entry stone coffin enclosure) — the earliest known example of this burial form. The side-entry stone enclosure, which allows lateral placement of the deceased while retaining a coffin shape, is a direct technical forerunner of the burial facilities in Kamiuchisakozuka (id:266), Takamatsuzuka (id:264), and Kitora Kofun (id:278) in Asuka. Located on the southern slope of Mt. Nijo at the western edge of the Nara basin, it is a key reference site for the evolution of terminal Kofun burial culture.
