• Odakyu Odawara Line: Kaisei ⇄ Tomizu

Kayama Station opened on 1 April 1927 with the Odakyū Odawara Line; initially only "chokutsū" through-services to Shinjuku stopped. The station became a stop on regular local services in June 1945 when local trains were extended across the whole line. Semi-express service was introduced from 1 October 1946 and commuter semi-express service from 25 March 1960 to 5 November 1964. Some express (kyūkō) services began stopping on 22 March 1983, and semi-express stopping ended on 15 March 2008 when semi-expresses no longer ran west of Shin-Matsuda. Station number OH 43 was assigned in January 2014. On 17 March 2018 the timetable revision saw express trains running local between Odawara and Hon-Atsugi reclassify their type at Shin-Matsuda, so Kayama was removed from the express stop list; the same revision ended through services from Kayama to the Hakone Tozan Line.

Kayama is known as the birthplace of Ninomiya Sontoku (also known as Kinjirō), and his birth house and the Sontoku Memorial Museum stand within walking distance. The station's name derives from the local place-name Kayama (栢山), which in the past was written 賀山 before drifting into its present form. The station consists of two opposed side platforms with separate gates on each side, connected by a footbridge; the platforms hold six-car trains, and the only toilet, AED, and waiting room are on the platform-1 side.
