Official website
Kagawa Prefecture, the smallest prefecture in Japan by area, is called the "Udon Prefecture." Sanuki udon is the everyday food of local people. Because the area gets little rain, many irrigation ponds are scattered across it. The art islands of the Seto Inland Sea, such as Naoshima and Teshima, attract travelers from around the world.
