The J2 League (Japanese: J2リーグ, Hepburn: J2 Rīgu) or simply J2 is the second division of the Japan Professional Football League (日本プロサッカーリーグ, Nihon Puro Sakkā Rīgu) and the second level of the Japanese association football league system. The top tier is represented by the J1 League. It (along with the rest of the J.League) is currently sponsored by Meiji Yasuda Life and it is thus officially known as the Meiji Yasuda J2 League (Japanese: 明治安田生命J2リーグ). Until the 2014 season it was named the J.League Division 2. Second-tier club football has existed in Japan since 1972; however, it was only professionalized during the 1999 season with ten clubs. The league took one relegating club from the top division and nine clubs from the second-tier semi-professional former Japan Football League to create the J2 League. The remaining seven clubs in the Japan Football League, the newly formed Yokohama FC, and one promoting club from the Regional Leagues, formed the nine-club Japan Football League, then the third tier of Japanese football. The third tier is now represented by the J3 League.
