New subway line, F!
The new subway line, F line, will be open on 14th June. F means Fuku-toshin line, vice center line, and the line will be running through major shopping areas, like Shibuya, Shinjuku and Ikebukuro. I know stations in such areas are very complicated and very easy for travelers to get lost. The new line will make the areas easier to access each other but, on the other hands, make the stations more labyrinth.
