AKB48 Group , or AKB48 sister groups, shortened to 48 Group or 48g, refers to the sister groups of the Japanese idol girl group AKB48. Based on the same concept "idols you can meet", it currently consists of five sister groups in locations across Japan and seven sister groups in major Asian cities overseas from Indonesia to Thailand. The Japan-based sister groups not only release their own singles, but also perform on some of the AKB48 singles and events. They also send participants in the AKB48 annual events such as the AKB48 general election. The sister groups outside Japan release local-language versions of the AKB48 singles. In their early development, they are often supported by temporary, concurrent members of AKB48, such as Jurina Matsui and Miyuki Watanabe.
