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.[12]

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 polyphenol 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.
