Mitoyo
Mitoyo lies on the coast of western Sanuki, where salt making became a prominent industry. At Nio, salt fields were developed along the shore, and their produce travelled by boat to Kawanoe and inland toward Awa. Boats that brought pine leaves for fuel carried salt on their return journeys. In the 1830s new salt fields were laid out at Nio, adding to the long-established industry of the Inland Sea coast.
