Former Japan national team player Atsuto Uchida detailed the new rules and equipment arriving for the 2026 FIFA World Cup on Thursday.

These changes arrive as the tournament expands to its largest scale in history. The adjustments aim to streamline game management and reduce delays in a competition featuring more teams and matches than ever before.

The 2026 tournament, hosted across the U.S., Canada, and Mexico, will feature 48 teams [1]. This is a significant increase from previous tournaments, which consisted of 32 teams and 64 matches [1]. The expanded format will result in a total of 104 matches [1].

To manage this increased volume and prevent game disruptions, the International Football Association Board (IFAB) is introducing measures to crack down on time-wasting, including a proposed "five-second rule" [2]. The IFAB also approved an expansion of the Video Assistant Referee (VAR) intervention scope, which now includes the issuance of second yellow cards [3].

Uchida also discussed the introduction of a new match ball for the tournament [4]. While these technical updates aim to modernize the game, Uchida said the increased difficulty for teams like Japan to advance deep into the bracket.

"Japan is aiming for the quarterfinals, but in a knockout tournament where one loss means you are out, you have to win twice to get there," Uchida said. "It is difficult for Japan."

The combination of a larger field and stricter officiating is designed to ensure that the increased number of games does not lead to a degradation of match quality or excessive stoppages [2, 3].

“The 2026 tournament... will feature 48 teams.”

The expansion to 48 teams fundamentally alters the tournament's logistics and competitive balance. By implementing stricter time-wasting rules and expanding VAR capabilities, FIFA and IFAB are attempting to mitigate the risk of 'dead time' and officiating errors that could be magnified across 104 matches. For smaller nations or underdogs, the increased number of games provides more opportunity, but the path to the quarterfinals now requires a higher level of consistency and endurance.
