Johnny &amp; Associates also produced new groups such as Hey! Say! JUMP, Tackey &amp; Tsubasa, NEWS, Kanjani Eight, and KAT-TUN. In 2006, KAT-TUN's debut single "Real Face", written by Shikao Suga and composed by Tak Matsumoto, sold over one million copies and topped the Oricon Yearly Charts. In 2007, temporary Johnny's Jr. group Hey! Say! 7 broke a record as the youngest male group to ever top Oricon charts, with an average age of 14.8 years. Later that year, Hey! Say! JUMP broke a record as the largest group to debut in Johnny's history, with ten members. They also became the youngest group ever to perform in Tokyo Dome with the average age of 15.7 years old. On the 2008 yearly singles charts, only one single ranked in the top 30 was sung by a female (Namie Amuro's single "60s 70s 80s") except gender-mixed groups, partly because the boy bands enjoyed an advantage in physical single sales. In 2009, Johnny's Jr. artist Yuma Nakayama w/B.I.Shadow became the youngest artist to have their first single to debut at the number-one spot, as the band had an average age of 14.6 years, breaking the former record set by female group Minimoni, 14.8 years.
