Japan began to develop a fierce rivalry with fellow Asian powerhouse Australia, shortly after the latter joined the Asian Football Confederation (AFC). The rivalry is 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 AFC in 2006. The rivalry began at the 2006 World Cup where the two countries were grouped together, and continued with the two countries meeting regularly in various AFC competitions, such as the 2007 AFC Asian Cup, the 2011 AFC Asian Cup Final and the 2013 EAFF East Asian Cup. Likewise, Australia and Japan also share a World Cup and continental records that is nearly unrivaled in Asia, and also similar that football is not the main sport in both nations until recently; yet hold an indistinguishable record that being the only three members from the AFC to have reached the final of any senior FIFA competition, the other being Saudi Arabia, both in the defunct FIFA Confederations Cup, albeit Australia achieved it when the country was still belonged to the OFC.
