History
Kōmyōike Station opened on 20 August 1977 in Minami Ward, Sakai, Osaka, on what is now the Nankai Semboku Line; it carries station number NK91. The station and surrounding new town take their name from Kōmyōike, a reservoir built in 1936 and itself named for Empress Kōmyō, with a small monument at the lake commemorating the Korean labourers who constructed it. On 1 April 2025 the line's operator, Semboku Rapid Railway, was absorbed into Nankai Electric Railway, bringing the station directly under Nankai. The station consists of an elevated island platform with the station building below; it is 12.1 km from the opposite terminus at Nakamozu and 25.5 km from Namba.
