Examples of spouted bowl-shaped pottery with attached pedestal foot (kyakudaitsuki hachigata doki) comprise ceramic vessels with a high foot and spouted body. These large, highly decorated ceramic objects have been unearthed in the northern part of Bingo (eastern part of Hiroshima Pref.). They have been investigated alongside with the characteristic burials of this region, rectangular graves with burial mound and four corner projections (yosumi tosshutsugata funkyū bo). It is also the case that similar pottery is distributed over a wide area encompassing the Chūgoku and Shikoku regions. Comparative research concerning patterns, surface finishing, feature situations, and the means of the attachment of the spout suggests that these artefacts can be roughly divided into those from the northern part of Bingo and those from other areas. This result further demonstrates the uniqueness of the northern part of Bingo.In the northern part of Bingo these large objects were continuously manufactured from the end of the Middle Yayoi period throughout the first third of the Late Yayoi period (1st century AD). This special pottery was used for funerary rituals. Particularly, it was commonly placed as offerings in the Sata-dani and Sata-dao groups of graves with burial mound in Shōbara city, Hiroshima Pref. Concerning forms and manners of offering, it is thought to have been strongly influenced by the southern part of Okayama Prefecture (Kibi). In addition to strong influences of the Kibi region, funerary rituals were performed using traditional ritual utensils.

According to the 1969 investigation report regarding the "Shijikkan-kohara" which was excavated a year earlier, it comprised a series of pit graves (dokō bo) from the Yayoi period. However, a more recent reinvestigation of this site suggests instead that a rectangular-shaped grave with multi-row stone pavement on the slope of the burial mound (hōkei hariishi bo) is the case here. Therefore, "Shijikkan-kohara" has been re-defined as a Yayoi period grave with burial mound (yayoi funkyū bo).It was constructed in the last third of the Middle Yayoi period and contained five burial facilities. These facilities, including some for children, were built prior to the construction of the burial mound. According to this fact, it was built using the so-called "mound last" method, where the burial mound construction is carried out at the end, after the burial facility is dug out respectively erected (funkyū kōkōgata; "mound last" construction type).The ways through which one constructed the mound and the stone pavement and arranged the burials, were also investigated. Similarly, the Narahama Yayoi period burial mound group and the Umeda-kayamine burial mound in the Chūgoku region were both constructed using the "mound last" method. As both of them were built during the Middle Yayoi Period, one could shed light on the development of the construction method concerning the relationship between the burial facilities and the mound. It changed from the "mound last" type to "concurrent progression" type (here, the mound and the burial facilities are simultaneously constructed) to the "mound first" construction type, where the piling up of the burial mound proceeds first. In addition, it concerns the stone pavement at the mound base as well as boundary stones (hyōseki) on top of the grave pits such as stone alignments enclosing or paving the grave (haiseki) and arrangement of the the burials are indicating an initial type. This can be considered them as an ancestral form of Yayoi burial mounds in the Chūgoku region. Also the possibility can be assumed that this situation developed from burials practices which were already present in the San'in region and the Chūgoku mountainous regions during the first half of the Yayoi period.Accordingly, the "Shijikkan-kohara" Yayoi period burial mound is an important archaeological site for studying the origin and evolution of such graves with burial mounds during the Middle Yayoi period in the Chūgoku region.
