History
Nishi-Tomioka Station opened on 15 October 1937 as Byōinmae Station ("in front of the hospital") on the Jōshin Line in what is now the Nanokaichi district of Tomioka, Gunma Prefecture. Operations were suspended on 1 September 1951 and the station reopened under its present name on 15 January 1953. According to the Japanese-language Wikipedia article, the current station building was completed in 1960 and the stop became a kan'i itaku (entrusted) station in 1968; the English-language article gives 1968 as the building's completion date, a conflict left for review.

Notes
The station was originally named Byōinmae — literally "in front of the hospital" — in reference to the nearby Nanokaichi Hospital, before being renamed Nishi-Tomioka in 1953 when service resumed after a brief 1951 suspension.
