History
Kōsei Station opened on 1 October 1981 as a new station on the JNR Kusatsu Line between Mikumo and Ishibe, built to handle traffic for the Biwako Kokutai sports meet of the same year. It is the youngest station on the line. With privatisation on 1 April 1987 it passed to JR West, automatic ticket gates were installed in January 1999, ICOCA support arrived on 1 November 2003, and an elevator entered service on 18 March 2015. The station is a barriered single-platform halt with an elevated concourse, today the central station of Konan City; local government has long lobbied JR West to add a passing loop here.

Notes
A D51 steam locomotive originally displayed in the north plaza was donated to machine-tool maker Yamazaki Mazak in August 2008 and now lives at the Mazak Museum of Machinery, freeing the rotary for redevelopment work.
