Nanakuma Line

The Nanakuma Line (七隈線, Nanakuma-sen) is a subway line, part of the Fukuoka City Subway system in Fukuoka, Japan. It runs from Hashimoto Station in Nishi Ward to Tenjin-Minami Station in Chūō Ward, all within Fukuoka. The line's color on maps is green. Officially, the line is called Line 3 (Nanakuma Line) (3号線(七隈線), San-gō-sen (Nanakuma-sen)). Like other Fukuoka City Subway lines, stations are equipped with automatic platform gates, and trains are automatically operated by ATO system.

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. Construction on a 1.6 km extension from Tenjin-Minami to Hakata station via Canal City received its final planning permissions in 2014, and is expected to be completed by 2020.
