Beautiful sand patterns changing with climate and seasons
Located in the San’in Kaigan Geopark, the Tottori Sand Dunes are one of the biggest sand dunes in Japan, extending 2.4 km from north to south and 16 km from east to west. Deeply-eroded spots with up to 40m depth are called “mortar.” Also, the shapes of the sand beautifully change with the influence of wind and climate. Wind-wrought patterns on the sand called “sand ripples” and sand grains forming a curtain-like pattern on slopes will capture your heart. At different times, the sand dunes can look very different. An oasis often appears especially in the snowy and rainy season, from winter to early spring. Normally, water would permeate through sand, but here at the Tottori Sand Dunes, there is volcanic ash underneath the sand and it stops the water from seeping through. At its deepest, the water depth can be over 140 cm. When winter comes, the sand dunes show another face. When it snows, the place showcases beautiful white scenery of snow-covered dunes.
