• Tokyu Ikegami Line: Yukigaya-otsuka ⇄ Kugahara (Tokyo)

Ontakesan Station opened on 4 May 1923 as Ontakesan-mae on the Ikegami Electric Railway, in what is now Kitamine-chō, Ōta, Tokyo. It was shortened to Ontakesan on 1 June 1929. The line is now the Tōkyū Ikegami Line and the station carries the code IK10. It operates as a service-manager station monitored remotely from Kamata. Two ground-level side platforms (one section elevated) each have their own ticket gate with no in-station crossover. The name comes from a branch of Ontake Shrine, whose head shrine sits atop Mount Ontake on the Nagano–Gifu border.

The station takes its name from Mount Ontake, enshrined at a local branch of Ontake Shrine, and the district around the station once prospered as a lodging town for pilgrims of the Ontake faith.
