It is named after Joo Koon Circle, the road which the station lies on, and the road in turn was named after Joo Koon Village, a rural Chinese settlement that stood in the area before the area became an industrial estate in the 1960s. This station serves people in Joo Koon, Gul Circle, Benoi, Kian Teck and Pasir Laba.
The roof of the station resembles those of stations along the eastern section of the East West Line and is curved with glass openings to allow the utilization of natural lighting, similar to that of Pioneer.
Built alongside with Pioneer, it was part of the Boon Lay MRT Extension (BLE) project announced by the Land Transport Authority in December 2004 to help people working in the Jurong Industrial Area travel faster.
The station opened on 28 February 2009 and replaced Boon Lay as the western terminus of the East West Line. However, this will not last long as Tuas Plaza will open in 18 June 2017 as the next terminus.
As with most of the above-ground stations built in the past along the East West Line, it was built without platform screen doors that prevent commuters from falling onto the train tracks. Installations of the half-height screen doors was eventually started on 16 May 2011. On 26 July 2011, all of the screen doors have been installed and began operating.
This station was installed with Rite Hite Revolution High Volume, Low Speed (HVLS) fans and in operation since 19 August 2012.
As Joo Koon will cease to be the westbound terminus from 18 June 2017, certain westbound trains will be withdrawn from service at this station after morning and evening peak periods.
