The line was originally opened in March 1975 to transport San'yō Shinkansen trains from the Hakata terminal to Hakata Depot in Kasuga. At that time, Kasuga was a rural region and did not merit a railway station of its own. By the late 1980s, however, the area had become a sprawling suburb of Fukuoka. JR decided to build a station adjacent to the depot, and inaugurated service on 1 April 1990 with 0 Series Shinkansen trains.^[1]
