History
Nishi-Ōya Station opened on 28 February 1936 on the Tōbu Ogose Line, 4.4 km from Sakado on the single-track branch. The name comes from the former Ōya village and was prefixed "Nishi" because it lay west of Ōya Station, which closed in 1945. In May 1963 a junction east of the station was built to serve a Nippon Cement plant; the spur ran for two decades before being abandoned in August 1984. Driver-only operation began on the Ogose Line in June 2008, with platform-edge sensors and television monitors fitted earlier that year, and station numbering as TJ-42 was introduced on 17 March 2012. A universal-access toilet was added during fiscal 2012.

Notes
Most of the alignment of the former cement-works branch from Nishi-Ōya has been reused as roads, with no rail equipment left in place.
