■Chūō・Sōbu Line（Local）

The Chūō/Sōbu Line Local trains operate on a 60.2 km route connecting Chiba Station in Chiba City, Chiba Prefecture, and Mitaka Station in Mitaka City, Tokyo. The journey between these two stations takes approximately 1 hour and 30 minutes. The section between Chiba and Kinshichō Stations runs parallel to the Sōbu Rapid Line, while the section between Ochanomizu and Mitaka Stations runs parallel to the Chūō Limited Express Line. The only section where it operates independently is the 4-station stretch between Kinshichō and Ochanomizu Stations.

Additionally, through service operates between Tsudanuma and Nishi-Funabashi stations and between Nakano and Mitaka stations with the Tokyo Metro Tōzai Line. Within these sections, you can see Tokyo Metro rolling stock and E231-800 series trains.

The Chūō/Sōbu Line local trains run parallel to the rapid line for most of their route and serve numerous transfer stations to other lines, resulting in high passenger volume even outside rush hours. Furthermore, the line is familiar to many people during events, as its route includes sports and concert venues and hosts fireworks displays.

A key feature is that most sections run on elevated tracks. Starting from the suburbs of Chiba Prefecture, the line traverses residential areas, gradually approaching the city center as it crosses rivers like the Edogawa and Arakawa. It then passes through the outer moat of Edo Castle near Yotsuya and the bustling Shinjuku district, continuing on to the western suburbs of Tokyo.

Because the Chūō/Sōbu Local Line traverses the city center from east to west, the character of the train changes mid-journey—from a “train heading from the suburbs to the city center” to a “train heading from the city center to the suburbs.” Enjoy the ride as it crosses the city center, savoring the slowly changing scenery unique to a local train.
