Keikyū Ōtsu Station opened on 1 April 1930 as Shōnan-Ōtsu Station on the Shōnan Electric Railway in Yokosuka, Kanagawa Prefecture. It became part of Keihin Electric Railway in November 1941, the wartime Tokyu conglomerate in May 1942, and the present Keikyū at the company's 1 June 1948 founding. The stop was renamed Keihin-Ōtsu on 1 November 1963 and reached its present name on 1 June 1987. An old wooden station building still serves as the entrance and houses ticket and turnstile equipment near the No. 1 platform. Keikyū assigned the stop number KK62 when it introduced system-wide station numbering on 21 October 2010.

A small Inari shrine stands beside the station building; local accounts date its founding to 1713 and name Uka-no-Mitama as its deity. Its torii were donated by Keikyū and Keikyū Construction, and the station's own staff are said to take part in the shrine's annual hatsu-uma festival.
