The Kōtoku Line (高徳線 Kōtoku-sen ) is a railway line owned and operated by Shikoku Railway Company (JR Shikoku). It connects the prefectural capitals of Takamatsu in Kagawa Prefecture and Tokushima in Tokushima Prefecture. The route hugs the northeastern coast of the island of Shikoku. Its name comes from the characters in the names of the prefectures that the line connects: Takamatsu (高松) and Tokushima (徳島).
In addition to local trains that run the entire length of the Kōtoku Line, there are trains that run between Takamatsu and Orange Town, Sambommatsu, and Hiketa, as well as between Tokushima and Itano and Tokushima and Hiketa. For a single-tracked line service levels are quite high, except along the prefectural border between Itano and Hiketa. In Tokushima there are through trains to/from the Naruto and Mugi lines, with one train per day running from Takamatsu to Mugi via Anan.
Since the completion of electrification work between Takamatsu and Iyoshi on the Yosan Line, the Kōtoku Line has received some of the newest DMUs on the JR Shikoku network. Local services often use 1000 series, 1200 series and 1500 series DMUs, while limited express services are handled by N2000 series DMUs.
- Local trains stop at all stations. For details of the Uzushio limited express service see that article.
- Trains can pass one another at stations marked "◇" and "^" and cannot pass at those marked "｜".
