Ai Otsuka
Each year since 2002, Avex has hosted a summer concert tour around Japan, "A-Nation", featuring the company's most successful acts. It is held every weekend in August in different Japanese cities. Top Avex acts like Ayumi Hamasaki, Kumi Koda, AAA, Ai Otsuka, BoA, Do As Infinity, Hitomi, TRF, Every Little Thing and TVXQ perform to major crowds each year. In 2008, Namie Amuro made her first appearance at A-Nation and performed on all dates that year. For the first time in 2012, Kumi Koda did not perform due to her pregnancy.
