Japanese Kofun in Maps given by a Spaceborne Digital Elevation Model based on Multiple Satellite Data Sets, for a Study about these Ancient Tumuli spanning from Remote Sensing to Geomancy

A study leveraging spaceborne digital elevation models (DEMs) reveals that many ancient Japanese Kofun tombs, particularly from the Early and Middle Kofun periods (3rd to 5th centuries), exhibit a strong preference for orientations facing south or west. This pattern aligns with geomantic traditions, where the northeast direction—associated with inauspiciousness and taboos—is notably underrepresented among these burial sites. The research utilizes high-resolution satellite data, including DEMs and Google Earth imagery, to analyze the spatial distribution and orientation of Kofun tumuli, providing insights into their possible astronomical or ritualistic significance. Additionally, the study explores the architectural features of keyhole-shaped tombs, which often contain dual burial chambers oriented along the tumulus's long axis, further supporting the connection between landscape positioning and funerary practices.
