130m early keyhole mound in Kashiwara City. The central mound of the Matsutakeyama kofun group; nationally designated historic site. The occupant is thought to have been a powerful chieftain controlling the Yamato River trade route.
A composite stone coffin (6 stone slabs) is exposed at the rear circle summit, with stone slabs scattered around — suggesting the vertical-shaft stone chamber was stack-stone type. Kashiwara City designated historic site and tangible cultural property. Finds include bronze mirrors, ornaments, weapons, agricultural tools, pottery, and haniwa (including flanged elliptical cylinder type). The nationally designated cultural property "Fune-no-Shio-Ogo epitaph" and Important Cultural Property triangular-rimmed deity-beast mirrors from the surrounding area indicate this as an important Yamato River basin political center.
Perched on a hilltop along the Yamato River in Kashiwara City, offering panoramic views of the Kawachi Plain. Finds are exhibited at the Kashiwara City Historical Museum. About 20 min walk from Kintetsu Osaka Line "Hosen-ji" station.
