Susa Hornfels
One of the Sea of Japan coast’s most representative geological landscapes, with rock strata from Approx. 14 million years ago exposed.
A dramatic cliff formation along the Sea of Japan coast in the nationally designated scenic area of Susa Bay, known for its dark-colored rock surface and layered structure. Alternating layers of sandstone and mudstone were transformed by the heat of magma Approx. 14 million years ago, and the exposed rock hardened as a result.
It is widely known for its striking striped rock surface, but the defining feature of hornfels is that the rock has turned black and hardened due to thermal metamorphism caused by magma. For this reason, in recent years it has sometimes also been described as “Tatami Iwa,” a name that focuses on its visual appearance.
You can take in the whole view from above, and there is also an Approx. 500-meter walking path from the parking lot down to the base of the cliff, where you can observe the rock surface up close. In September 2018, Hagi Geopark was recognized as a Japanese Geopark, and Susa Hornfels is positioned as one of its component assets. The ground is quite rocky, so comfortable walking shoes are recommended.
