## Lines

### Osaka Metro

* Chūō Line (Station Number: C10)
* Nankō Port Town Line (Station Number: P09)

## History

* The station opened to rail traffic on December 18, 1997. 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.
* A potential extension to the artificial island of Yumeshima was first discussed in the 1990s as part of Osaka's failed bid to host the 2008 Summer Olympics. The Yumesaki Tunnel [ja], which opened on August 1, 2009, was built with space for the Chūō Line to extend westward to Yumeshima (this segment now called the OTS North Technoport Line [ja]), which is now expected to be completed in 2024 in time for Expo 2025 to be held at said site.
