Takamatsu (高松市, Takamatsu-shi, Japanese: [takaꜜmatsɯ]) is a capital city located in Kagawa Prefecture, Japan.

The northern part faces the Seto Inland Sea, forming a semicircular urban area centered on Takamatsu Port and Takamatsu New Port (commonly known as Shinminato).The western part of the city consists of an alluvial fan formed by the sedimentation of the Koto River.

During the Heian and Kamakura period, as the closest port to Honshu from Shikoku island, the area was a transportation center and gateway for pilgrims to the Kotohira Shrine.

[6] Following the Meiji restoration, the city of Takamatsu was created with the establishment of the modern municipalities system on February 15, 1890.

During World War II, Takamatsu was selected as a target by the United States' XXI Bomber Command because the city was an important focal point of Shikoku's rail and road transit systems, and containing some industry vital to supporting the war effort.

On July 3, 1945, at 6:40 pm (JST) 128 B-29 Superfortress bombers dropped over 800 tons of incendiary bombs on Takamatsu, destroying 78% of the built-up areas of the city and killing 1359 people.

Takamatsu has a mayor-council form of government with a directly elected mayor and a unicameral city council of 40 members.

Buses and trains operated by Kotoden accept a contactless payment card for travel called an IruCa.
