Heading into the 2026 FIFA World Cup, both Japan and Mexico were seen as two underrated teams who could turn out to be the dark horse of this year’s tournament.
Having impressed with their fearless displays in Qatar, Japan have only improved under the tutelage of Hajime Moriyasu, and the Blue Samurai were expected to improve on their round of 16 exit from four years ago.
Mexico, meanwhile, are one of the co-hosts of the tournament, and they were expected to enjoy success in front of home support.
Both teams have lived up to the hype so far.
Japan put in a measured performance in their tournament opener to draw 2-2 with a star-studded Netherlands team, before dismantling Tunisia 4-0 to go joint top of Group F.
On the other hand, Mexico have already secured first place in Group A by winning their first two games against South Africa and South Korea respectively, keeping clean sheets in both fixtures.
While plenty can be said about Japan and Mexico’s solid performances on the field, the friendly bond between fans of both nations has recently come under the spotlight.
During Japan’s game against Tunisia, which took place at Estadio Monterrey on Saturday, some Japanese supporters were spotted sporting Mexican hats, shouting out the culture of their hosts.

Several Mexican fans were also spotted at the arena, some of whom were dressed as Sumo wrestlers, while others carried banners declaring their support for the Blue Samurai.

It didn’t take long for this to become a hot topic on social media.
Fans on social media commended the Mexican fans for “having a big heart” and turning up to a game their country wasn’t even playing in. Others claimed such camaraderie between two nations is the “best part” of the World Cup.
Fans also wondered if all the love the Japanese were receiving was a result of the “good football” they played. A few Mexican fans also chimed in to state they cheered for the Samurai to support the “great Japanese people”.
Looking into the historical relations between both nations, this mutual admiration looks to be something that goes beyond football.
Back in 1888, Mexico signed a treaty with Japan which stated that both nations would view each other as equals, becoming one of the first nations to do so. Ever since, the two nations have been on good terms.
Today, the Mexican embassy in Japan is located in Nagatacho, one of the most important areas in Tokyo.
After the game, Japan boss Hajime Moriyasu also expressed gratitude for the Mexican support his team received.
“To all the Mexican fans who cheered for Japan — thank you so much. We truly appreciate it,” Moriyasu said.
Next, the Japanese head to the United States to take on Sweden in Arlington, for their final game of the group stage. Mexico, on the other hand, will take on the Czech Republic in Mexico City.
