Route map

The Chūō-Sōbu Line (中央・総武緩行線, Chūō-Sōbu-kankō-sen) is a railway line that runs through Tokyo and Chiba Prefecture, Japan.

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.

Service patterns

Chūō-Sōbu Line

  • Regularly, trains terminate at Chiba or Tsudanuma at the east side, and terminate at Nakano or Mitaka at the west side
  • All trains stop at every station.

Tozai Line through service

All through service trains enter the Tozai Line at either Nakano, or Nishi-Funabashi. These trains operate within the following routes:

  • Mitaka – Nakano – (Tozai Line) – Nishi-Funabashi – Tsudanuma (mornings/evenings only)
  • Nakano – (Tozai Line) – Nishi-Funabashi – Tsudanuma (mornings/evenings only)
  • Mitaka – Nakano – (Tozai Line) – Nishi-Funabashi
  • Mitaka – Nakano – (Tozai Line) – Nishi-Funabashi – (Toyo Rapid Railway Line) – Toyo-Katsutadai

Early morning / Late night

At around 9 -10pm, 5 westbound trains head beyond Mitaka onto the Chūō Line (Rapid), with 3 terminating at Musashi-Koganei, and the other 2 at Tachikawa. The other trains during the hour operate regularly.

At around 4 - 6am and 11pm - 1am, Chūō-Sōbu Line services are divided at Ochanomizu Station, into two sections.

  • At the western section (Mitaka – Ochanomizu), Chūō Line (Rapid) trains run through the Chūō-Sōbu Line tracks between Nakano and Ochanomizu, with services serving between Tokyo and as far as Takao, or even Ōme, which stops at all stations.
  • At the eastern section (Ochanomizu – Chiba), local trains operate and terminate at the two ends of the section.

Limited express

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.
