Overview
122m late-period keyhole mound in Aoyama, Fujiidera City — the IHA-designated mausoleum of Emperor Ninken (Hanyu-no-Sakamoto-no-Misasagi). The name "Bokeyama" is variously attributed to the Japanese quince (boke) flowers once blooming nearby. A large keyhole mound built as late as the early 6th century shows that elite power in the Furuichi area persisted into the late Kofun period.
Finds & research
The mound is unexcavated under IHA regulations. Outer-bank surveys (Osaka Pref. BoE 1975/1979; Habikino City BoE 1981) confirmed cylindrical haniwa rows and two haniwa kilns.
