History
Chitose-Karasuyama Station opened on 15 April 1913 as Karasuyama Station on the Keiō Electric Tramway, taking its name from the surrounding Karasuyama district of the former Chitose Village. The stop was renamed Chitose-Karasuyama on 7 August 1929. Wartime mergers transferred it to Tokyu in May 1944, and the post-war split on 1 June 1948 placed it under Keio Teito Electric Railway, the company that became today's Keio Corporation. Station renovation works were completed in August 2011, continuous grade-separation works began on 28 February 2014, and a March 2022 schedule reshuffle promoted the stop from a Semi-Limited Express stop to a Limited Express stop after eliminating the Semi-Limited Express category.

Notes
The level crossing immediately east of the station is well known as a so-called "crossing that won't open" — a railway crossing whose barriers stay closed for long stretches during the morning and evening rush, frequently cited on Japanese television programmes about chronic urban bottlenecks.
