History
Kita-Koshigaya Station opened on 27 August 1899 with the inaugural Tobu Railway stretch between Kita-Senju and Kuki, originally named Koshigaya Station for the nearby post town. After the southern Koshigaya Station (now Koshigaya) was added in 1919, this stop was renamed Bushū-Ōsawa on 20 November of that year, then renamed again to Kita-Koshigaya on 1 December 1956. Tobu's first overhead-bridge station building was built here in March 1962 to coincide with the start of through running to the Tokyo Metro Hibiya Line. The platforms were elevated between 1998 and 1999, and a quadruple-tracked section to Koshigaya opened in March 2001. Station-numbering label TS-22 was assigned on 17 March 2012.
