The E231 Series operating on the Joban Line was introduced in 2002 to replace the 103 Series.

Seen in both 10-car and 5-car formations, the E231 Series runs in a maximum 15-car formation as an electric commuter train.

In addition to its main turquoise line color, an olive-green stripe was added to help prevent passengers from confusing it with trains on the local (slow) line.

Alongside the E531 series, which is used for medium-distance services, it operates on the Joban Rapid Line between Ueno and Toride, as well as the Narita Line between Abiko and Narita. Since the opening of the Ueno-Tokyo Line in 2015 (Heisei 27), its area of operation has expanded further, and it now runs through to Shinagawa.
