Outline of Final Research Achievements

This research aimed at the reconstruction of the detailed three-dimensional shape of keyhole-shaped burial mounds with the use of new technologies such as laser metrology. At first four large scale tumuli in Osaka and Okayama have been analyzed and established their standard designs. The use of right-angled triangles were speculated for determining slopes and the unit of measurement for length was the scale imported from China. Next, we have tried to apply this method for smaller mounds and those in other regions. A paper on the result of analyzing four tumuli and the result of newly laser-scanned mounds were published in 2018.
