Istvan Kovacs will make his 2026 World Cup debut refereeing the match between Tunisia and Japan, two teams desperate for a win. Kovacs has never officiated in this FIFA tournament before, making this a massive milestone for him as well.
Kovacs averages 5.12 yellow cards per game. That tendency could benefit Japan, who face a physical, high-stakes battle against a Tunisia squad needing a victory to keep their dreams of advancing past the group stage alive.
Because it’s a crucial match for Tunisia, they earned the ‘right’ to wear their primary all-white kit. Japan will counter with the eye-catching blue uniform that has generated so much buzz during this World Cup.
Uniforms for Tunisia and Japan
Tunisia hope a massive stadium and a passionate soccer city bring them some luck. They will wear their official all-white kit with red trim, while their goalkeeper will be in all-orange.
Japan will sport their traditional all-blue uniform with white and red details. They naturally had to ditch their white jersey and black shorts alternative to avoid a clash with Tunisia. Their goalkeeper, US-born Zion Suzuki, will wear an all-yellow kit.
Referee for Tunisia vs. Japan
Even though Kovacs has never been on a World Cup stage, he knows there is no room for error in a match where both squads are hungry to advance and climb the FIFA rankings.
