 This is the fourth linear motor subway line to be built in Japan, opening on 3 February 2005.The Nanakuma Line was originally conceived in the 1960s to provide access to Nakamura Gakuen University and Fukuoka University, and in 1975 it was planned to run from Tenjin-Minami Station to Jōnan Station as a linear-motored subway, but the plan was subsequently amended for the line to end at Hashimoto Station.The line links the Central business district and the southwestern part of the city, which did not have a railway transport.
