History
Ōhara Station opened on 13 December 1899 as the terminus of the Bōsō Railway in present-day Isumi, Chiba Prefecture. The Bōsō Railway was nationalised on 1 September 1907, and on 1 April 1930 the connecting Kihara Line (now the Isumi Line) opened. Freight handling ended on 1 February 1984. The Kihara Line, designated a first-stage specified local line, was spun off as the third-sector Isumi Railway on 24 March 1988, after the 1 April 1987 JNR privatisation that placed the Sotobō Line under JR East. Suica service began on the Chiba side on 16 October 2004 and on the Awa-Kamogawa side on 14 March 2009. The Midori-no-madoguchi closed on 31 March 2024.

Murals by artist Kensuke Miyazaki and students of Chiba prefectural Ōhara and Ōtaki high schools decorate the Isumi Railway platform, which also doubles as the line's souvenir shop selling express tickets.
