• Nishi-Kyushu Line: Kouda (Matsuura Railway) ⇄ Saza

Seihō-Kōkō-mae Station opened on 20 January 1959 as the newly established "Kami-Sasa Station" between Hizen-Kanda and Sasa Stations on JNR's Matsuura Line. It became a JR Kyushu Matsuura Line station at the JNR privatization of 1 April 1987, and was converted to the third-sector Matsuura Railway on 1 April 1988, becoming a station on its Nishi-Kyushu Line. Nearby Nagasaki Prefectural Seihō High School represented Nagasaki at the national Kōshien high school baseball tournament for three consecutive seasons from 2005 to 2006, becoming runner-up at the 78th Selection Tournament — a phenomenon known as the "Seihō Whirlwind." In response, in August 2006 the mayor of Sasa requested that Matsuura Railway rename the station, and it was renamed "Seihō-Kōkō-mae Station" in the timetable revision of 18 March 2007. It is an unstaffed station with one side platform and one track, and its waiting room bears a mural painted by Seihō High School students.

Two years after the renaming, in 2009, Seihō High School's baseball team won the 81st Selection Tournament, achieving the first national championship by a school from Nagasaki Prefecture in either the spring or the summer tournament; the station name became a symbol of the "town-wide support" in which the school's rise and local enthusiasm bore fruit.
