Geopark Programme aims to build sustainable local communities. This requires an understanding of Traditional Geographical Knowledge (TGK). One of these TGKs is the choice of residential areas. People live by making good use of the natural topography. We considered that the coastal villages in the San’in Kaigan Geopark Area also use the natural topography, and categorized the relationship between the topography around the coastal villages and background of the coastal villages.
The San’in Kaigan Geopark is divided into Tango Peninsula Area (marine terrace and rocky coast with advanced erosion, partly Rias coast), Tajima coastal Area (Rias coast), and eastern Tottori Area (rocky coast with advanced erosion). We paid attention to the coast of Kyotango City, unlike the Rias coast, having a well-developed marine terrace where natural inlets are difficult to form.
The factors that formed the topography and the background of its use as a fishing port will be clarified. As a result of investigating the geology and topography of the place where the fishing port is located on Tango Peninsula (Kyotango City), all fishing ports (13 ports) have been used the naturally formed cove-like topography, and 7 of them had rocky topography.Among them, andesite and sedimentary rocks were confirmed in 6 of the 7 fishing ports. It was found that andesite is distributed especially in the cove, where it protrudes like a cape.
