When Saki Kumagai slotted home the winning penalty in a dramatic shootout victory over the United States in Frankfurt on Sunday, Japan completed an astonishing run that overshadowed any achievement by an Asian football team at any level.
"There is no happier president than a World Cup winner," Japan Football Association (JFA) president Junji Ogura said after the side had rallied twice to force extra-time and a penalty shootout, which they won 3-1.
"The players demonstrated the wonders of Japanese women."
With their women crowned world champions and the "Blue Samurai" currently on top in Asia, envious eyes will be cast at Japan from their continental rivals to far beyond.
South Korea put Asian football firmly on the map with their remarkable run to the 2002 World Cup semi-finals as tournament co-hosts with Japan.
However, despite success at Asian club level, South Korea have flattered to deceive since, while the domestic K-League has been tainted by an embarrassing match-fixing scandal.
China, the world's most populous country and second largest economy, has failed to make much of a dent in the game despite qualifying for their first World Cup in 2002.

Tadanari Lee's stunning volley to give Japan's men a 1-0 victory over Australia in the Asian Cup final in Doha in January displayed similar jaw-dropping technique and flair.
Sawa, who has scored 80 goals in 173 games for Japan, has appeared in five World Cups and is famous in her home country, appearing in Nike commercials among her many endorsements.
She has now shot to fame worldwide, leading by example as Japan's women gave the public back home a welcome shot in the arm after the deadly earthquake and tsunami in March.
Nicknamed "Nadeshiko" after a frilly pink carnation symbolising the traditional ideal of the stoic Japanese woman, coach Norio Sasaki's side captured the hearts of a nation.
