Tōtōmi Outward Sea
The sea off Tōtōmi, also called Enshū-nada, washes a long arc of sandy coast between Cape Omaezaki and Cape Irago. The Tenryū River reaches the sea near the middle of this shore, where extensive dunes rise behind the beach. Offshore, the warm Kuroshio flows eastward, and its waters support fish such as bonito. Winter winds carry sand along the exposed coast and help shape the dunes.
