J2 League
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.
