History

Overview of the original Asakusa Station terminus (present-day Tokyo Skytree Station) in 1927

An up express service on the Tobu Isesaki Line formed of a 4-car EMU in March 1940

The Isesaki Line was opened in 1899 between Kita-Senju and Kuki with steam motive power by the present company. In 1902, Tobu extended south to have a maritime connection at present Tokyo Skytree (then Azumabashi (吾妻橋), later renamed Asakusa) in downtown Tokyo, and north to Kazo. In the next year further north extension to Kawamata (then on the south bank of Tone River) was opened. Gradual extension northward progressed, and in 1910 the line arrived Isesaki. In 1931, a bridge over the Sumida River was built and present Asakusa Station (then Asakusa Kaminarimon (浅草雷門)) opened as part of the department store building, the entire stretch completed.

Electrification was begun in 1924 on the section of Asakusa and Nishiarai, and in 1927 completed as far as Isesaki. The distance of over 100 km was then one of the longest electrified railway lines together with the present Kintetsu Osaka Line and Kintetsu Yamada Line.

After World War II, the Tobu Lines had no connection to the Yamanote Line or other major lines of the then Japanese National Railways (JNR) to offer efficient transfers to central Tokyo. The sole connection was with the Jōban Line at Kitasenju, which offered poor access to central Tokyo. To solve the inefficiencies of transfers at Kitasenju and notoriously narrow Asakusa, in 1962, the Hibiya Line of the then Teito Rapid Transport Authority (帝都高速度交通営団, Teito Kōsokudo Kōtsū Eidan), known as TRTA, present Tokyo Metro) was built, connecting at Kitasenju.

Further growing traffic required Tobu to build a second through line to Tokyo Metro Hanzomon Line in the 1990s. In 2003, the company built new tracks from Hikifune to connect at Oshiage, officially an annex station of Tokyo Skytree.

On March 3, 2006, the revised timetable changed past operations greatly, with only less than half of trains originating or terminating at Asakusa, and more trains operating through to Tokyo Metro underground (subway) lines.

From 17 March 2012, the section south of Tōbu-Dōbutsu-Kōen was split off to become the Tobu Skytree Line.
