Over 200 members of Nigeria's official supporters' club left Lagos on Wednesday to cheer the team at the World Cup finals.
With their musical instruments in tow, they belted out songs that they will be singing during the tournament.
"We're hoping to arrive Kobe in time on Friday to cheer the Eagles to victory against Sweden," Yusuf Adenrele, head of the supporters club, told BBC Sport Online.
They said a delay in securing Japanese entry visas and hitches in travelling arrangements delayed their departure.
According to their flight schedule, the group will fly to Tokyo through Dubai and Hong Kong.
On arrival in Japan, they will travel by train to Kobe, where they hope to cheer the Super Eagles to victory over Sweden on 7 June.
"We were upset at missing the Argentina game because our presence would have made the difference," said Rafiu Oladipo, the group's leading figure.
"But we're confident we can beat Sweden and qualify for the second round."
The West Africans have only played Sweden once - in a 1994 friendly in Stockholm, which they lost 3-1.
