An emergence-period mound in the hills of Shingu, Tatsuno. Its six mirrors place a west-Harima chieftain within the early Yamato mirror-distribution network. Reached by a hill path — a kofun you hike to.

Archaeological view
A 36m keyhole mound (or ~30m) on a hill ridge, among the oldest in the Ibo valley (late 3rd century). Its pit-style chamber (~5.4m) held traces of a split-log coffin and yielded six bronze mirrors — including triangular-rimmed examples — glass beads, and a sword fragment (mirrors in the Tokyo National Museum). Small but scholarly important for its Kinai-style burial goods at the dawn of the period.
