The Tottori Sand Dunes ( 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 .

Many of the largest sand dunes are found here, and their tops provide visitors with beautiful views out over the coast. From here you can also explore the vast expanses of sand which lead off for several kilometers in almost every direction.
