The Tobu Railway Company, Ltd. (東武鉄道株式会社, Tōbu Tetsudō kabushiki gaisha) is a Japanese commuter railway and keiretsu holding company in the Greater Tokyo Area as well as an intercity and regional operator in the Kantō region. Excluding the Japan Railways Group companies, Tobu's 463.3 km (287.9 mi) rail system is the second longest in Japan after Kintetsu. It serves large portions of Saitama Prefecture, Gunma Prefecture and Tochigi Prefecture, as well as northern Tokyo and western Chiba Prefecture. The Tobu Railway Company is listed in the First Section of the Tokyo Stock Exchange and is a constituent of the Nikkei 225 index.

The Tobu corporate group is also engaged in road transportation (bus/taxi), real estate, and retail. It is the owner of the Tokyo Skytree, the third tallest tower in the world. The company is a member of the Fuyo Group keiretsu.

The name "Tobu" is formed from the kanji for east (東) and Musashi (武蔵), the initial area served.

History

Tobu is one of the oldest railway companies in Japan. It was established in November 1897 and began operation between Kita-Senju and Kuki in August 1899. The Tojo Railway was founded in 1911 as a separate company, but shared its president and head office with Tobu.^[3]

In 1905, Nezu Kaichirō became the president of Tobu Railway and successfully helped to grow the company to one of the largest private rail operators in the Kanto region.^[4]

In 1924, Tobu began operating its first electric train on the Isesaki Line between Asakusa (later Narihirabashi, today Tokyo Skytree Station) and Nishiarai.

Tobu was the first railway in the Kanto region to adopt quadruple tracks, on the Kita-Senju to Takenotsuka sector in 1974.^[5] The Tobu Dobutsu Koen (Tobu Animal Park) opened in 1981.^[6]

Railway network

Tobu has two isolated networks which are connected by the Chichibu Railway for ferrying of its rolling stock.

The Tobu Main Line network has a tree topology starting at Asakusa in Tokyo, with the Isesaki Line as the trunk, and the Tobu Kameido Line, Daishi Line, Tobu Urban Park Line, Tobu Sano Line, Koizumi Line, Tōbu Kiryū Line, and Nikkō Line forming the branches, with further branches into the Tobu Utsunomiya Line and Tobu Kinugawa Lines. It offers surcharged, seat-reserved limited express services from Tokyo to Nikkō and Kinugawa.

The Tojo Line runs northwest from Ikebukuro in Tokyo to central and western Saitama Prefecture. A branch, the Ogose Line, runs to Ogose from Sakado.

Tobu's terminals in Tokyo are at Asakusa (Main Line express services), Oshiage (most other Main Line services) and Ikebukuro (Tojo Line). The Skytree and Isesaki Lines interoperate with the Tokyo Metro Hibiya Line, Tokyo Metro Hanzomon Line and the Tokyu Den-en-toshi Line to serve central, southwestern Tokyo and Kanagawa Prefecture, while the Tojo Line interoperates with the Tokyo Metro Fukutoshin Line, Tokyo Metro Yurakucho Line, Tokyu Toyoko Line and Minatomirai Line to serve central and southwest Tokyo and Kanagawa Prefecture.
