History
Kokusai-Tenjijō Station opened on 30 March 1996 with the inauguration of the Rinkai Fukutoshin Line (now Rinkai Line) between Shin-Kiba and Tokyo Teleport, serving the adjacent Tokyo Big Sight exhibition complex. It was selected as one of the Kantō Station 100 in 1997 with the citation "a station whose translucent Teflon-membrane roof evokes a covered wagon." Suica IC service began on 1 December 2002, when the line was rebranded "Rinkai Line." Half-height platform-edge doors entered service on 30 September 2018, and on 18 March 2019 a 2.6 × 8.8 m ceramic relief by Osamu Tezuka was permanently installed on the concourse. The station carries number R-03.

Notes
The station building's roof is shaped like a covered wagon and clad in translucent Teflon membrane, designed to provide a spacious, high-ceilinged concourse able to absorb crowd surges when events run at the adjacent Tokyo Big Sight. The single underground island platform serves two tracks, and many trains inter-run with the JR East Saikyō and Kawagoe lines, providing through services to Kawagoe in Saitama. Although the station is officially named after the exhibition centre, locals more often refer to the area by the surrounding place-name "Ariake."
