Kagawa-ken

Kagawa-ken (Kagawa Prefecture) is a prefecture of Japan located on Shikoku island. The capital is Takamatsu. Kagawa comprises the northeast corner of Shikoku, bordering Ehime Prefecture on the west and Tokushima Prefecture on the south, with a coastline on the Seto Inland Sea facing Okayama Prefecture and the Kansai. The Sanuki Mountains run along the southern border.

Kagawa is currently the smallest prefecture, by area, in Japan. Osaka Prefecture held that title until Kansai International Airport was reclaimed from the ocean in the early 1990s, pushing its land area slightly above Kagawa's. Kagawa is a relatively narrow prefecture located between the mountains of Shikoku and the sea.
