Since opening of Nanakuma Line in 2005, inconvenience of transferring to Airport Line from Tenjin-Minami has been pointed out. After many kinds of extension plans were suggested, a route runs from Tenjin-Minami to Hakata via Canal City Hakata was adopted.
On April 9,2012, Fukuoka Municipal Subway applied to Kyusyu transportation bureau for a patent to operate the railway line.
On June 11,2012, the patent will be accepted.
I've taken the line only between Tenjin-Minami and Yakuin. After full extension of the line, I'd like to take all of the line.
