Tottori Prefecture stretches along Japan's San'in coast on the Sea of Japan, home to the Tottori Sand Dunes, the country's largest coastal dune system, and the yokai-themed Mizuki Shigeru Road in the port town of Sakaiminato. Japan's least populous prefecture, Tottori pairs a dramatic, uncrowded coastline with Mount Daisen's hiking trails, the white-walled storehouse district of Kurayoshi, and radium-rich hot springs at Misasa and Kaike Onsen.
