• JR Nippo Line: Tsurusaki ⇄ Sakanoichi

Ōzai Station was opened by Japanese Government Railways on 25 November 1924 as an additional stop on the existing Nippō Main Line. Following the privatisation of Japanese National Railways on 1 April 1987 it passed to JR Kyushu. The operator had planned to convert Ōzai, along with several other Ōita City stations, into an unstaffed, remotely-managed Smart Support Station by 17 March 2018, but the plan was postponed after user opposition while accessibility works were carried out; the conversion was finally implemented on 1 July 2023. The station serves Ōzai, a village absorbed into Ōita City, and is the closest stop to Nippon Bunri University in the adjacent Sakanoichi suburb.
