Tateiwa (Standing Rock)

Tateiwa rock represents the Tango area in the San’in Kaigan Geopark. It is a huge monolith with a height of 20 meters. This boulder is made up of hardened magma that emerged from a geological stratum, including volcanic dust which accumulated over 15 million years ago. Since rocks which emerged from beneath the earth’s layers are harder than other rocks, it has withstood erosion from the sea better than the surrounding rocks. Tateiwa Rock is loved as a symbol for the local area.
