History
Takaoka Station opened on 10 September 1989 with the new Sakuradōri Line section between Nakamura-Kuyakusho (today's Taikō-dōri) and Imaike, in Higashi-Sakura 2-chōme, Higashi-ku, Nagoya. Platform-edge gates entered service on 9 April 2011. The name preserves the pre-address-change place name Takaoka-chō, which itself derives from the surviving Owari-Tokugawa-affiliated temple Takagaku-in (also pronounced Kōgaku). Original plans called for the Kami-Iida Line to be extended from Heian-dōri to Takaoka, but that proposal was shelved. The station has an island platform able to accept eight 20-metre cars; because a shared utility duct sits above the platforms, the platform width of 18.9 metres — equalled only at neighbouring Hisaya-Ōdōri — is the widest of any station on the Nagoya Municipal Subway.

Notes
Together with neighbouring Hisaya-ōdōri Station, Takaoka has the widest platform of any station on the Nagoya Municipal Subway at 18.9 metres — a consequence of the utility duct running directly above the station.
