154m keyhole mound in Fujiidera City.One of the earliest mounds in the Furuichi group (late 4th century), reflecting the group's formative phase following Tsudoshiroyama. The mound survives amid residential streets, and the curving roads around it still trace the ancient outline.
Confirmatory surveys by Fujiidera City Board of Education have verified the basic structure including the rear circle and surrounding moat. Jasper bracelet-type artifacts, iron objects, and mirrors have been traditionally recorded (details unclear). Cylindrical haniwa and stone paving confirmed.
