A square mound (~37m per side) in the Furuichi group, dated to the late 5th century. A national historic site known for Osaka University's excavation and the publication of a publicly accessible 3D digital archive. Iron implements, Haji ware, and Sue ware were recovered from a horizontal stone chamber. Square mounds are abundant in the Furuichi group and functioned as accessory burials alongside the large keyhole mausolea. The digital archive is an exemplary case of remote access to detailed archaeological documentation.Constituent monument of the "Mozu-Furuichi Kofun Group" UNESCO WHS (2019). The place name "Nonaka" (In the Fields) reflects the mound's open-field location.

Osaka University's digital archive is publicly accessible online, allowing smartphone users to view 3D images of the stone chamber interior—a leading example of digital cultural heritage utilization.
