The song "Koi Suru Fortune Cookie" by AKB48 is to be used as the departure melody on the Hibiya Line platforms from spring 2016.
It was opened to passenger traffic in 1925 following the construction of the section of track linking Ueno with Shimbashi via Tokyo Station and the completion of the Yamanote Line.
The upper level platforms were added in 1932 with the opening of an extension to the Sōbu Line from its old terminal at Ryōgoku to Ochanomizu, making Akihabara an important transfer station for passengers from the east of Tokyo and Chiba Prefecture.
The huge growth in commuter traffic following the Second World War caused considerable congestion and was only relieved with the construction of the Sōbu line tunnel linking Kinshichō with Tokyo, bypassing Akihabara.
The station facilities of the Hibiya Line were inherited by Tokyo Metro after the privatization of the Teito Rapid Transit Authority (TRTA) in 2004.
