The Tottori Sand Dunes (鳥取砂丘, Tottori Sakyu) are the largest sand dunes in Japan and Tottori's most famous tourist attraction. Located just outside the city center, they span roughly 16 kilometers of coast along of the Sea of Japan and are up to two kilometers wide and 50 meters high. They are part of the Sanin Kaigan National Park.
The sand dunes were created over thousands of years, as sand from the nearby Sendaigawa River was washed out to sea and eventually redeposited along the coast by the ocean's currents. Today, the constant movement of the tides and the coastal winds continuously shape the sand dunes and provide an ever changing landscape.
