The Tottori sand dunes are the largest in Japan, covering 2.4km north to south and 16km east to west. The area is designated a natural monument. The wind ripples created by the winds coming from the Sea of Japan on the sand dunes are a mesmerizing sight. As an active member of the Mingei Movement, Yoshida devoted himself to the conservation of the sand dune landscape which was under threat of forestation development.
