Kagawa Prefecture (香川県, Kagawa-ken) is a prefecture of Japan located on the island of Shikoku.[4] Kagawa Prefecture has a population of 949,358 (as of 2020)[2] and is the smallest prefecture by geographic area at 1,877 square kilometres (725 sq mi).[1] Kagawa Prefecture borders Ehime Prefecture to the southwest and Tokushima Prefecture to the south.

Takamatsu is the capital and largest city of Kagawa Prefecture,[5] with other major cities including Marugame, Mitoyo, and Kan'onji. Kagawa Prefecture is located on the Seto Inland Sea across from Okayama Prefecture on the island of Honshu, which is connected by the Great Seto Bridge. Kagawa Prefecture includes Shōdoshima, the second-largest island in the Seto Inland Sea, and the prefecture's southern land border with Tokushima Prefecture is formed by the Sanuki Mountains.



Kagawa was formerly known as Sanuki Province.[6]

For a brief period between August 1876 and December 1888, Kagawa was made a part of Ehime Prefecture.[7]

Battle of Yashima


Located in Kagawa's capital city, Takamatsu, the mountain of Yashima was the battlefield for one of the best-known struggles between the Heike and Genji clans.



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. Kagawa is a relatively narrow prefecture located between the mountains of Shikoku and the sea.

As of April 1, 2012, 11% of the total land area of the prefecture was designated as Natural Parks, namely Setonaikai National Park and Ōtaki-Ōkawa Prefectural Natural Park.[8]

People queuing for udon in Kagawa

Sanuki udon (a type of udon noodle) is the most famous local food of Kagawa Prefecture. In 2008, there were over 700 udon restaurants in this prefecture alone.[13]

Aside from udon, Kagawa is also famous for "hone-tsuki-dori", seasoned chicken thigh cooked on the bone. Originating from Marugame City, the dish has now become a popular dish in izakaya restaurants across the country.

Olives and olive-related products have also come to be recognized as Kagawa foods. As the first place in Japan to successfully cultivate olives, Kagawa has been producing olive-related products since 1908. As well as winning both domestic and international awards for the quality of its olive oil, Kagawa has also created two offshoot food brands from its olive industry - "olive beef" and "olive yellowtail". Waste organic matter from olive pressing is used as feed for cattle and the Yellowtail Amberjack. Due to the high amount of polyphenols in the olive waste, the flesh of the respective meats does not oxidize or lose color easily.

Other local specialties include wasanbon sugar sweets, sōmen noodles and shōyu soy sauce. Rare sugar researches are thriving and have discovered mass production culture enzymes. D-tagatose 3-epimerase is an enzyme that catalyzes the reversible epimerization reaction of the 3rd carbon of ketose.
