JKT48 (read as "J. K. T. forty-eight") is an Indonesian-Japanese idol girl group whose name is derived from its based city of Jakarta and the Japanese idol group AKB48. Formed in 2011, the group is the first AKB48 sister group outside Japan and adopts the concept of "idols you can meet", before switching to "idols that will come to meet you" since April 8, 2018. The group opened their own theater in the 4th floor of fX Sudirman shopping mall in early September 2012, where fans can attend daily performances (except on Monday). The theater was built as a close replica to the AKB48 Theater in Akihabara.
