This is AKB48
In December 2005, producer Yasushi Akimoto created the idol group “AKB48”. “AKB” stands for Akihabara, Tokyo. With the concept “Idols you can meet everyday”, AKB48 performs at the exclusive AKB48 Theater in Akihabara almost every day.
AKB48 consists of 3 groups, that is, team A, team K and team B. Teams A and K have 16 members, and team B has 17, reaching a total of 49. This number has officially certified by the Guinness book as the largest for a pop group in the world.
AKB48’s music single CD includes a vote ticket once a year. So the buyer can vote their favorite member per CD. As result, 21 members will be selected and they will perform the next song (the 32nd single CD.) This year the single “Sayonara Crawl” released on May 22, sold 1.763 million copies in its first week, the biggest first-week single CD sales ever.
