The Tottori Sand Dunes are unique sand dunes located near Tottori City in Japan. The largest sand dunes span roughly 16 kilometers of coast along of the Sea of Japan and are up to two kilometers wide. The highest dunes reach around 90 meters above sea level and can reach 40 degree slopes.
The sand dunes were created over thousands of years, as sand from the nearby Sendaigawa River was washed out to sea. Sea currents and wind help bring the sand from the bottom up onto the shore, where the constant movement of the tides and the coastal winds continuously shape the sand dunes and provide an ever changing landscape. The area of the dunes has been steadily decreasing due to a government reforestation program following World War II.
