Koshigaya

Departure data for this station is not available on this site.

Koshigaya Station opened on 17 April 1920 as Tobu Railway's first petition-built station, secured after the town of Koshigaya-machi accepted the company's conditions — a 16,000 yen donation, a new road of at least four ken linking the Nikkō-kaidō to the station, and freight contracts from local merchants — in its campaign for a stop closer to the old Nikkō-kaidō post town. The kanji rendering of the name was simplified from "越ヶ谷" to "越谷" on 1 December 1956 after the town's amalgamation. The west entrance was added in August 1989. Platforms were elevated in stages between 1993 and 1994, and the section between Sōka and Koshigaya was made quadruple-tracked in March 1997. Station-numbering label TS-21 was assigned on 17 March 2012, and platform-edge doors were installed in 2022 (local lines) and 2025 (express lines).

A commemorative stone marking the petition-driven opening was moved to nearby Hisa-izu Shrine during a 1972 plaza expansion, then returned to its original east-entrance spot in 2011.
