Designated as a National Natural Monument, this stunning location offers a surreal and mysterious landscape. After passing through a seaside cave from the Kokufu Beach, visitors emerge onto a vast, flat rock expanse known as \"Senj\u014djiki\", stretching out before them like a natural stone plaza the size of the Tokyo Dome.\n\nScattered across the surface are round, stool-like rocks, creating a whimsical scene that looks as if it were pulled straight from a fantasy world, with the sea as its backdrop. The surface of the rock is crisscrossed with regular, grid-like cracks, resembling tatami mats\u2014hence the name Tatamigaura.
This is a marine terrace, formed from seafloor strata deposited around 16 million years ago, which was uplifted by tectonic activity, including the Hamada Earthquake of 1872 (Meiji 5). Fossils of whale bones, shells, and other marine life can be easily spotted embedded in the rocks.\n\nThe unique round \"stool-like\" formations are called nodules, formed when fossilized material acts as a nucleus for mineral buildup over time.\n\nWith its wealth of unusual geological features, Tatamigaura is truly a \u201cnatural geological museum\u201d\u2014a place where science and fantasy beautifully intersect.<\/p>\n\n\n\n
