Topographical Survey of the Chōja Sukumozuka Mounded Tomb No.2 in Saijō, Higashi-Hiroshima City
The Chōja Sukumozuka mounded tomb No.2 is a keyhole-shaped or round mounded tomb located in Saijō-chō, Higashi-Hiroshima City, Hiroshima Prefecture. Because it was robbed in the 1950s and a box-shaped stone coffin (hakogata sekkan) was exposed on its mound, there was an urgent necessity to examine this mound. In September 2017, as part of “Field Practice in Archaeology A and B” for the archaeology majors at the Hiroshima University School of Letters, we conducted a topographical survey of this mound to clarify its scale, shape, and date of construction. The results of this survey indicated that the Chōja Sukumozuka mounded tomb No.2 is a keyhole-shaped mounded tomb with a diameter 28.5m, or a round mounded tomb with a diameter 22.0m of the Kofun period. The date of construction of this mounded tomb is not clear; however, we believe that this mound was constructed after the beginning of 5th century AD due to the spatial relation to the Chōja Sukumozuka mounded tomb No.1. In addition, as a result of reviewing previous information about this mounded tomb, we would like to point out that the mounded tomb, which is currently regarded as No.2, was once referred to as No.3, and there were two box-shaped stone coffins.
