History
Oiwake Station opened on 15 August 1912 with the Keishin Electric Tramway's Sanjō-Ōhashi to Fudanotsuji section. Successive mergers placed it under Keihan Electric Railway in 1925, Keihanshin Kyūkō in 1943, and once again Keihan in the 1949 separation. The conversion of National Route 1 prompted the line to be moved off its shared roadway onto a dedicated alignment on 16 February 1932; further realignments in 1974 (Nishi-Ōtsu Bypass IC) and 1979 shifted the tracks 15 m north and then further west. Platforms were extended in 1996 for four-car 800-series operation. Automatic ticket gates entered service on 1 March 2002 with the Surutto Kansai rollout, PiTaPa on 1 April 2007. In 2013 a typhoon flooded the underground passage. Station number OT33.

Notes
Reflecting Ōtsu's status as the birthplace of the Ōtsu-e folk-painting tradition, when the platforms were rebuilt for four-car 800-series operation in 1996 a pair of reproductions of Ōtsu-e paintings was hung on each platform shelter wall.
