Could Japan be the World Cup's dark horses?

There is always at least one team that defies the odds and emerges as the surprise package of a World Cup.

Just ask Morocco, Russia, and Costa Rica, three nations who have all produced memorable runs deep into the knockout stages in recent years despite the modest expectations heading into the tournament.

With the World Cup having expanded from 32 to 48 teams this time around, there appears to be more potential dark horses than ever before.

But few nations look better equipped for a deep and unexpected run than Japan, whose blend of individual quality, recent form and all-round experience makes them one of the most intriguing outsiders in the competition.

In 2022, the Samurai Blue defeated both Germany and Spain to top Group E and advance to the first knockout round.

But it wasn't to be. Instead, Japan suffered familiar heartbreak as they were eliminated at the round-of-16 stage for the fourth time after a penalty shoot-out defeat by Croatia.

Now, four years on, as they prepare for their opening game against the Netherlands on Sunday night (21:00 BST), there is a growing belief that this could the most successful of Japan's eight World Cup appearances.

Sweden and Tunisia are the other teams in Group F, and Japan are currently unbeaten in their past nine matches against European opposition.

Former Southampton defender Maya Yoshida believes the 26-man squad selected by manager Hajime Moriyasu is capable of reaching unprecedented territory in the United States, Canada and Mexico.

Yoshida, 37, who captained Japan in 2022, has travelled with the squad to this tournament as a non-playing "support player" to provide leadership behind the scenes.

"For me, reaching the quarter-finals - a stage we've never reached or even experienced before - is the main goal," Yoshida told BBC Sport. "Anything beyond that would be a bonus."

'My goal is for the team to be one of the best of the best'

It is not only Yoshida who has set the bar high for Japan.

Earlier this year, Moriyasu said he had his sights set on leading Japan to World Cup glory this summer.

"My goal is for the team to be one of the best of the best," Moriyasu told World Soccer Magazine before the tournament. "We have raised our level little by little through our national team activity.

"For me the task is to bring out the best in the players. We do have a lot of injuries but we have also proven that we have the squad to produce our best regardless of who plays"

It is little surprise the 57-year-old is so confident in the players at his disposal, which includes Daichi Kamada of Crystal Palace and Ao Tanaka of Leeds United.

They helped Japan become the first non-host nation to secure their spot at this summer's finals after an almost perfect qualifying campaign.
