Seibu-Shinjuku

Departure data for this station is not available on this site.

Seibu-Shinjuku Station opened on 25 March 1952 in Kabukichō 1-chōme, Shinjuku, as a temporary terminus when Seibu's Murayama Line — renamed the Shinjuku Line at the same time — was extended south from Takadanobaba. Seibu had received a 1948 licence to push the line through to the east side of the national railway's Shinjuku Station, and helped fund the 1964 Shinjuku Station Building (today's Lumine Est), but the 8-car platforms that operations now required could not be fitted into the constrained site, and on 25 March 1965 the through-running plan was formally abandoned. The present 25-storey terminal with the Shinjuku Prince Hotel and PePe shopping centre opened on 3 March 1977, and the north entrance followed in October 1980.

When the line was first laid towards Shinjuku, Seibu's claim to the alignment came from the Shinjuku-line streetcar it owned until 1951 (Seibu Kidō Line, Shinjuku–Ogikubo) — the company kept the dormant section between Seibu-Shinjuku and Shinjuku as a licensed line rather than transferring the track to the Tokyo Metropolitan Government, and used that paper-right to justify the planned southern push.
