Ayase Station

Ayase Station is served by the following two lines.

• JR East Joban Line
• Tokyo Metro Chiyoda Line

The official boundary between the Joban Line and Chiyoda Line is located east of Ayase Station, past the turnoff for the Kita-Ayase branch of the Chiyoda Line. However, the segment of the Chiyoda Line between Ayase and Kita-Senju Station is treated as part of the Joban Line for fare calculation purposes when passengers do not travel on Tokyo Metro beyond Kita-Senju.

Ayase Station also serves as a turnaround point for the Odakyu 60000 series MSE Romancecar service through the Chiyoda Line, and is sometimes used as a delivery point for Tokyo Metro trainsets by rail; JR Freight transports the trainsets to Ayase during midnight hours, where Tokyo Metro takes delivery and hauls them to the nearby Ayase depot.

The stations has a side platform serving one track and two island platforms serving three tracks, and a rectangular cut out for Kita Ayase trains on a fourth track. It is the only station in Tokyo Metro to have a "Platform 0"
