# Shikoku Railway Company

The Shikoku Railway Company (四国旅客鉄道株式会社, Shikoku Ryokaku Tetsudō Kabushiki-gaisha), commonly known as JR Shikoku (JR四国, Jei-āru Shikoku), is the smallest of the seven constituent companies of the Japan Railways Group (JR Group). It operates 855.2 kilometres (531.4 mi) of intercity and local rail services in the four prefectures on the island of Shikoku in Japan. The company has its headquarters in Takamatsu, Kagawa.

## Lines

In 1988 JR Shikoku, unlike other JR companies, discontinued the classification of its rail lines as either main, secondary, or branch lines. Prior to the change, the Dosan, Kōtoku, Tokushima, and Yosan Lines had all been main lines.
Each line is color-coded and labeled with a letter, in conjunction with which a number is assigned to each station on the line. For example, Naruto Station on the Naruto Line (labeled N) is numbered N10. Although this method is now widely used by rail companies, especially metro systems in Japan, JR Shikoku was the first JR company to adopt it.
