Japan

The Japan national football team, nicknamed the Samurai Blue represents Japan in men international football, and it is controlled by the Japan Football Association (JFA), the governing body for football in Japan. Japan was not a major football force until the end of the 1980s, with its team small and amateur, but since the 1990s, when Japanese football became fully professionalized, Japan has quickly emerged as one of the most successful teams in Asia, having qualified for the last six consecutive FIFA World Cups with second round advancements in 2002, 2010, and 2018, and having won the AFC Asian Cup a record four times, in 1992, 2000, 2004 and 2011. The team has also finished second in the 2001 FIFA Confederations Cup and the 2019 AFC Asian Cup. Their principal continental rivals are South Korea, North Korea, China, and most recently, Australia; though they also develop rivalries against Iran, Iraq, and Saudi Arabia.
