History
Nishi-Koizumi Station is the terminus of Tobu Railway's Koizumi Line, located in Ōizumi, Gunma, 13.2 km from Tatebayashi at the opposing terminus and numbered TI-46. It opened on 1 December 1941 originally as a station on the Sengoku-Kashi freight line, serving as the gateway to the Nakajima Aircraft Company's Koizumi works. Until 1976 the freight line continued beyond the station to New Koizumi and Sengoku-Kashi yards; after closure the right-of-way was repurposed as the Izumi-ryokudō pedestrian pathway. A new station building entered service on 16 September 2017 in colours echoing the Brazilian flag — a deliberate civic gesture, since over 10% of Ōizumi's residents are foreign-born and the majority of them are of Brazilian descent.

Notes
Reflecting Ōizumi's large Japanese-Brazilian community, the 2017 station rebuild adopted yellow-and-green Brazilian colours, and the station's signage carries six languages: Japanese, English, Chinese, Korean, Portuguese and Spanish.
