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.
Japan national football team
Japan's earliest international matches were at the 1917 Far Eastern Championship Games in Tokyo, where it was represented by a team from the Tokyo Higher Normal School. Although Japan made strong showings in swimming, baseball, and track and field, its football team suffered resounding defeats to the Republic of China and the Philippines. Nevertheless, the game was promoted in Japanese schools in the 1920s. The Japan Football Association was formed in 1921, and Japan joined FIFA in May 1929.
