Cosmosquare Station (コスモスクエア駅, Kosumosukuea-eki) is a metro station on the Osaka MetroChūō Line and Nankō Port Town Line (New Tram) in Suminoe-ku, Osaka, Japan. This station serves as the starting terminus of both lines. This station is the westernmost station of the Osaka metro system as of 2024.
The station opened to rail traffic on December 18, 1997, and was managed by Osaka Port Transport System Co., Ltd. [ja]. The name "Cosmosquare" was selected in a public poll conducted in 1988 for residents of Osaka, relating to the development of "Techno Port Osaka" on the artificial islands of the Osaka Bay area.
On July 1, 2005, Osaka Municipal Transportation Bureau took over management of the station; Osaka Metro would take over management of the station on April 1, 2018.
A mini aquarium was installed on the subway platform at one time. Due to excessive maintenance costs and the relatively few users of the station, it was removed.
A different train approach melody was used on the station, playing a sound similar to that of an ocean wave. On March 27, 2007, the melody was changed to the standard approach melody that is used on the metro.
