Shibayama Kofun Cluster

The Shibayama Kofun Cluster contains two keyhole-shaped tombs and 13 dome-shaped burial mounds on the east bank of Kido River. The site displays varying sizes of burial structures, and excavations revealed rich grave goods including rings, swords, and horse fittings.

These burial mounds date from the 6th century and were designated as a National Historic Site of Japan in 1958. The recognition honored their importance for understanding ancient burial practices and society of that era.

The excavated clay figurines show scenes from burial ceremonies with horses, dogs, and people in different roles. These objects give visitors insight into ancient rituals and how people lived in that era.

The site is easily accessible by foot, around 5 minutes walking from Yokoshiba Nakadai bus stop. An airport shuttle from Keisei Narita Station offers a convenient route to reach the location.

The Tonozuka burial chamber has red-painted interior walls, a rare feature among excavated chambers of that period. This painted decoration offers clues about how such sacred spaces were decorated and their ceremonial importance.
