National Historic Site (1978).
Archaeological view
Himeji City gives this keyhole mound a length of around 100m; the Agency for Cultural Affairs records 109m. The city calls it the largest among Harima’s oldest-style tombs. A pit-style chamber over 2m long is known near the southern edge of the rear mound; the city infers that the main burial lies elsewhere. The Agency records stone paving and haniwa but says grave goods are unknown. On its date, Himeji City treats it as one of the oldest-style tombs, while the Agency's designation note places it in the Middle Kofun-period sequence of chiefs' tombs in the area, so the assessments differ.
