History
Heian-dōri Station opened on 20 December 1971 on the Nagoya Municipal Subway Meijō Line, when the line was extended from Shiyakusho (today's Nagoyajō) to Ōzone. A second line, the Kamiiida Line, opened to the station on 27 March 2003, making Heian-dōri an interchange and one of the only places in Japan where two subway lines cross perpendicularly. The Kamiiida Line, despite being operated by the Nagoya City Transportation Bureau, has its infrastructure owned by a third-party operator (Kamiiida Connecting Line Co., Ltd.), with the Transportation Bureau running services as a Type-2 railway operator. Platform-edge doors on the Meijō Line entered service on 11 October 2020.

Notes
Heian-dōri is the only station on the entire Kamiiida Line under Transportation Bureau management — the rest of the line's infrastructure is owned by a separate third-sector operator, and the Transportation Bureau runs trains across it as a Type-2 operator.
