These slippers are made in farm villages in northern Japan. They are made from naturally dried, woven corn husk. Inedible corn husks have been disposed of in very large quantities, but these slippers recycle and make use of them. In the autumn when corn is harvested, the corn husks are carefully peeled away and dried, and then in the winter when farm work comes to an end the husks are meticulously woven together. It is a process that requires an extremely difficult and time-consuming technique.
