From Kaushik on Amusingplanet.com: "Who would have thought there is a desert in Japan? Well, not quite a desert but a huge sand dune that looks nearly a desert to me. It’s the Tottori Sand Dunes located near Tottori City in Honshū, Japan. The dunes stretch along the coast east of Tottori City for 16 kilometers and extend up to 2 kilometers away from the coast. The dunes are spread over an area of 30 square kilometers – not like the Sahara, but not small either. The Tottori Sand Dunes were created by sediment deposits carried from the Chūgoku Mountains by the Sendai River into the Sea of Japan. Sea currents and wind help bring the sand from the bottom up onto the shore, where the wind constantly rearranges their shape. The highest dunes reach around 90 meters above sea level and can reach 40 degree slopes. Technically, its not a desert but the temperature of the sand can easily soar above 50C on sunny summer days. A number of hardy species of plants and animals also thrive in sections of the dunes. The dunes have existed for over 100,000 years, but the area of the dunes has been steadily decreasing due to a government reforestation program following World War II. Additionally, concrete barriers erected to protect the coast from tsunamis have disrupted the currents responsible for bringing the sand to shore.
