The Sagami Railway Company, Ltd. (相模鉄道株式会社, Sagami tetsudō Kabushikigaisha), or Sotetsu (相鉄), is a private railway company operating three lines in Kanagawa Prefecture, Japan. It is a wholly owned subsidiary of holding company Sotetsu Holdings, Inc. Sotetsu Holdings is listed on the Tokyo Stock Exchange; 6.58% of it is owned by the Odakyu Electric Railway Company.


Sagami Railway is one of the core companies of the Sotetsu group. Sotetsu focuses on railway operations, although formerly it had a more diversified set of holdings, such as bus lines and supermarkets. Sotetsu is the smallest company of the "Big 15" railways in Japan, as it has only short lines, but it succeeded in developing towns along its lines in the 1960s and 1970s, with many passengers ride this line. In May 1990, Sotetsu joined the major railways. In 2010 it had a daily ridership of 623,500[1]

As of 1 April 2016, Sotetsu operates the following electric multiple unit (EMU) train types.[2]

Further 20000 series trains will be delivered ahead of the start of inter-running services to and from Tokyu Corporation lines scheduled to commence in late fiscal 2022.[4]




Preserved fleet

Some withdrawn rolling stock is preserved at Kashiwadai depot.


The Sagami Railway was established in Chigasaki, Kanagawa, in January 1917, to transport gravel along the Sagami River valley. The first section, between Chigasaki and Samukawa was opened in 1919, and the line was extended gradually to Hashimoto in 1931.[5] Sagami Railway started direct operation to Hachioji, but performance was sluggish during the economic depression, so Sagami Railway became a subsidiary of Tokyu in 1941.

The Jinchu Railway was established in Seya village (now, Seya-ku, Yokohama) in 1917, and opened its first section from Futamatagawa to Atsugi in May, 1926. Jinchu Railway extended to Yokohama Station in 1933, but its management had financial difficulties, so the company also became a subsidiary of Tokyu in 1939, prior to Sagami Railway. The two companies' rail lines were connected at Atsugi Station.[citation needed]

In April 1943, Sagami Railway took over Jinchu Railway and named two lines "Sagami Line" (original section) and "Jinchu line" (acquired section). However, in June 1944, the Sagami Line and Nishi-Samukawa branch line were purchased by the government to use the bypass between Tokaido main line and Chuo main line. At the same time, Imperial Japanese Navy Atsugi Airport was opened, so the number of passengers and amount of freight increased sharply. As a result, Sagami Railway released all management and delegated it to Tokyu. Under Tokyu, the line gained electrification to increase the carrying capacity and in 1944, all passenger lines were electrified.[citation needed]

In June 1947, Sagami Railway employees bought their own shares from Tokyu and resolved the commission.[citation needed]

In 1952, Sagami Railway purchased the 25,000 m2 of land around Yokohama Station's west entrance from Esso, and began to develop to attract department stores.[citation needed]
