• JR Sotobo Line: Ohara (Chiba) ⇄ Katsuura

Onjuku Station opened on 20 June 1913 on what is now the Sotobō Line in the town of Onjuku, Chiba Prefecture. Freight handling was withdrawn on 1 July 1971 and parcel handling on 1 March 1972. The station passed to JR East at the privatisation of Japanese National Railways on 1 April 1987 and was integrated into the Tokyo suburban network when Suica IC-card ticketing began on 14 March 2009. From the 16 March 2013 timetable revision all Wakashio limited-express services have stopped here. The staffed Midori-no-Madoguchi reservation window closed on 31 May 2022, and the station is now operated under contract from a hub centre at Katsuura. It lies 65.4 km from Chiba.

The station name plaque incorporates a motif from the children's song "Tsuki no Sabaku" ("Moonlit Desert"), set on Onjuku beach, and a bronze statue of an ama diver stands at the Chiba end of the platform.
