01 / Domain border
Mounds on the Nanbu–Date domain borderstand both west and east of the Kitakami River.

The Nanbu-ryo Date-ryo Sakaizuka mounds were built in 1642 (Kanei 19) to mark the boundary between the Nanbu and Date domains. They consist of large mounds and small mounds, the small ones built to fill the gaps between the large ones. West and east of the Kitakami River, they remain on the line between the former Nanbu and Date domains.
