| Research Abstract |
To approach political interaction among local elites, we have investigated a series of sixth-century keyhole-shaped tumuli located in the northwestern coastal area of the Lake Kasumigaura, Ibaraki Prefecture, Japan. In this particular area, nine keyhole-shaped tumuli are located, two of which have been excavated and mapped. In Japanese archaeology, keyhole-shaped tumuli are considered as elite burial mounds. This area is very noteworthy because, while the construction of keyhole-shaped tumuli declined in the sixth century in the Nara, Kyoto, and Osaka Prefectures where the central polity was presumably located, the construction of keyhole-shaped tumuli became intensified. For this study, we have mapped five keyhole-shaped tumuli and two large (more than 40meters in diameter) circular tumuli, and obtained the following results.
Fifith century (in the chronological order of construction) :
Tsukayama (circular):49 meters in diameter, 8 meters in height
Momoyama (circular):39meters in diamete

r, 5 meters in height
Sixth century (in the chronological order of construction) :
Raidenyama (scallop-shaped keyhole mound with very short frontal mound):55.8m in length;48m in the diameter of the circular rear mound;9.0m in height;7.8m in length of the frontal mound
Atagozuka (scallop-shaped keyhole mound):59.5m in length;49.8m in the diameter of the rear mound;10.1m in height;9.7m in length of the frontal mound
Yamadamine (ordinary keyhole-shaped tumulus):83.6m in length;41.6m in the diameter of the rear mound;42.0m in length of the frontal mound;57.5m in width of the frontal mound;30.0m in the width at the joint of the rear and frontal mound
Takidai (ordinary keyhole-shaped tumulus):83.4m in length;36.1m in the diameter of the rear mound;47.3m in length of the frontal mound;49.8m in width of the frontal mound;29.3m in the width at the joint of the rear and frontal mound
Momoyama (ordinary keyhole-shaped tumulus):54.5m in length;30.4m in the diameter of the rear mound;24.1m in length of the frontal mound;37.4m in width of the frontal mound;23.0m in the width at the joint of the rear and frontal mound
Among those, we have placed test trenches at the Momoyama tumulus to determine the original mound size. We have also collected fragments of haniwa ceramic cylinders, which are useful for relative dating of tumuli, and the above are the results of our haniwa analysis. Less
