Australia–Japan football rivalry
The Australia–Japan football rivalry is a sports rivalry that exists between the national association football teams of each country, regarded as one of Asia's biggest football rivalries. The rivalry is a relatively recent one, born from a number of highly competitive matches between the two teams since Australia joined the Asian Football Confederation in 2006. The two teams have played each other in several significant matches, including a World Cup group stage match and the 2011 Asian Cup Final.
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.
