Chūō-Sōbu Line is part of the East Japan Railway Company (JR East) network, but it operates on separate tracks along the right-of-way of the Chūō Main Line (Chūō Line (Rapid)) and Sōbu Main Line (Sōbu Line (Rapid)), providing service between Mitaka Station in the cities of Mitaka and Musashino and Chiba Station in Chiba.
The term Kankō (緩行 lit. "slow run") distinguishes local trains on the Chūō-Sōbu line from rapid service trains running on the Chūō Main Line between Mitaka and Ochanomizu and on the Sōbu Main Line between Kinshichō and Chiba.

Certain limited express and seasonal trains run through, or stop at stations on this line. For information on the Shinjuku Wakashio and the Shinjuku Sazanami that make stops on the Chūō-Sōbu Line at Akihabara, see their respective articles.
