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 name for the line was selected in a naming contest.[3] "Nanakuma Line", which finished third, was selected over the first-place "Jonan Line" and runner-up "Fukudai Line" because of its stronger historical connotations as well as being more geographically accurate compared to the other names. Nanakuma is a district in Jōnan ward which is close to the center of the line.[3]

The line links the Central business district and the southwestern part of the city which previously did not have a railway line.

Future PlansEdit

Hakata Station extensionEdit

Construction on a 1.6 km (0.99 mi) extension from Tenjin-Minami to Hakata station via Canal City received its final planning permissions in 2014. Construction was initially scheduled to be completed by 2020, but delays after a sinkhole opening up in front of JR Hakata Station pushed the schedule up by three years.[4] On 7 January 2021, Fukuoka City announced the planned opening of the extension by March 2023.[5] The city also reported that there were no delays as a result of the COVID-19 Pandemic. The two-station extension is earmarked to begin operation on 27 March 2023.[6]

Fukuoka Airport extensionEdit

On 21 November 2022, Fukuoka mayor Sōichirō Takashima announced plans to extend the Nanakuma line to Fukuoka Airport.[7] The extension is expected to head east from the (future) terminus at Hakata Station and run for around 3.0 km (1.9 mi) to the international terminal at the airport.[8] Currently, the domestic terminal at Fukuoka Airport is served by the Kūkō Line on the subway network. However, the international terminal lacks a rail connection. A free shuttle bus currently connects the two terminals.[7]

Rolling StockEdit

The line currently employs four-car long 3000 series trains purchased in 2005 for the start of revenue service. There are 17 sets accounting for 68 cars.[9]

A further four sets were ordered in 2021. These sets, designated as 3000A series, will feature a blue and green livery and are intended for an increase in service when the Nanakuma Line is extended from Tenjin-Minami to Hakata, scheduled to open in 2023.[10]
