Railway station in Tokyo, Japan
 is an interchange station on the Odakyu Odawara and the Keio Inokashira lines located in Kitazawa, Setagaya, Tokyo, and jointly operated by the private railway operators Odakyu Electric Railway and Keio Corporation.
The station gives its name to the surrounding Shimokitazawa neighborhood in the southern corner of the Kitazawa district, which is a popular area for young people in large numbers. It includes small independently owned shops, cafes, live music venues and theaters.
Lines.
Shimo-kitazawa Station is served by the Odakyu Odawara Line from Shinjuku in Tokyo, and also by the Keio Inokashira Line from Shibuya in Tokyo to Kichijōji. Located between Ikenoue and Shindaita, it is from the Shibuya terminus of the Inokashira Line.
Service pattern.
On the Keio Inokashira Line, both all-stations "Local" services and limited-stop "Express" services stop at this station. On the Odakyu Odawara Line, only Limited Express services pass the station.
Station layout.
The Odakyu Odawara and Keio Inokashira lines cross at this station, with the Keio line on elevated tracks above the Odakyu line. After a major station reconstruction project, the Odakyu lines were relocated in March 2013 from their prior surface position to new platforms three stories underground. Additional construction work, ending in 2018, separated the express line trains from the local line trains, one level above. Now, the four-track route that formerly ended at Umegaoka is complete as far as Yoyogi-Uehara station.
An unusual feature of Shimo-kitazawa Station for many years was the use of a single ticket gate serving two independent lines and ticketing systems; this was a legacy of the Inokashira Line's former ownership by Odakyu. Additionally, there were no ticket gates between the two lines. However, as part of a major Station renovation construction project, this was changed in March 2019. Now, both lines have separate entrances and ticket gates, and it is necessary to exit and enter ticket gates in order to switch between lines.
