Ancient Geology

Tatamigaura in Shimane is a striking coastal wonder where ancient geological formations stretch out like giant tatami mats along the shoreline. Known as the Tatamigaura Rock-Flats Beach, this natural phenomenon was formed by tectonic uplift and erosion, revealing layered rock beds and fossilized remains. At low tide, visitors can walk across the broad stone flats, discovering seashell fossils and ripple marks frozen in time. The dramatic scenery is especially captivating during sunset, with waves crashing against the sculpted coastline. It’s a unique destination that blends natural history with coastal beauty.
