One of Harima’s large keyhole mounds, preserved in Mikunino, Himeji. A chest-style sarcophagus can be seen on the rear summit; a Tenman shrine stands on the front section.
Finds & research
A composite chest-style sarcophagus is visible on the rear summit, and the mound has paving stones and haniwa. Mirrors, blades, and beads came from the separately designated Tomb 3 (Yamanokoshi Kofun), not from the Danjozan mound itself.

The sarcophagus is identified as Tatsuyama stone. The occupant is unconfirmed.
