Nambu line

Introducing

DescriptionThe deNambu laLine ligneis a 35.5 km long line connecting Kawasaki Station in Kawasaki City, Kanagawa Prefecture and Tachikawa Station in Tachikawa City, Tokyo.

The predecessor of the Nambu Line was a private railroad company, Nambu Railway, which opened between Kawasaki Station and Noborito Station in 1927 for the purpose of transporting gravel from the Tama River. Later, in 1929, the entire line between Kawasaki and Tachikawa Stations, in its present form, was opened.

It is a commuter and school route that intersects with the Chuo Line rapid service radiating from central Tokyo, private railway lines, Yokosuka Line, Tokaido Line, and many other lines, connecting them in a circle, and is used as an important means of access between central Tokyo and the Tama region in the southern northern part of Kanagawa Prefecture.

Many electronics manufacturers and IT-related companies are located along the line, and the Musashi-Kosugi Station area is lined with high-rise condominiums as well as natural scenery such as the Tama River. The area is also characterized by many boat and bicycle racetracks and horse racing tracks.

In 2011, rapid transit service was restored for the first time in 32 years, and currently the fastest connection from Kawasaki Station to Tachikawa Station is 43 minutes.
