History
Hirooka Station opened on 10 July 1933 as a Japanese National Railways stop on the Shinonoi Line, handling passenger traffic only. The station became a contracted operation in July 1979 and ended parcel handling in February 1984. It joined JR East at the 1987 privatisation. A 2007 rebuild produced a new elevated station building and an east-west passage, with the eastern "National Route exit" opening on 22 December 2007 and works completed in February 2008. Hirooka was added to the Tokyo metropolitan tariff area in April 2014, gained Suica acceptance on 1 April 2017, and was assigned station number SN 02 in February 2025.

Notes
The two exits earned nicknames during the 2007 rebuild — the west exit, facing the older shopping street, is the "Tanka no Sato (Land of Tanka Poetry)" exit, while the east exit faces National Route 19 and is called the "Kokudō exit."
