Group stage tiebreakers 
In the group stage, teams in a group were ranked by points (3 points for a win, 1 point for a draw, 0 points for a loss). If the points were tied, the following tiebreakers were applied:

 Points in head-to-head matches among tied teams;
 Goal difference in head-to-head matches among tied teams;
 Goals scored in head-to-head matches among tied teams;
 Away goals scored in head-to-head matches among tied teams;
 If more than two teams are tied, and applying all head-to-head criteria above remains a part of teams still tied, reapply the criteria above only for the tied teams.
 Goal difference in all group matches;
 Goals scored in all group matches;
 Penalty shoot-out if only two teams are tied and they met in the last round of the group;
 Fewer disciplinary points;
 Drawing of lots.

In case of ranking third-placed teams across the groups, the following criteria were used:

 Points;
 Goal difference in all group matches;
 Goals scored in all group matches;
 Fewer disciplinary points;
 Drawing of lots.

Play-off stage 
The number of play-off stage participants depends on the number of teams advanced to ACL group stage.

 In case four teams advanced to ACL group stage, eight teams (top two teams in each group) would play the play-off.
 In case three teams advanced to ACL group stage, ten teams (top two teams in each group, and two best third-placed teams across the groups) would play the play-off.
 In case two teams advanced to ACL group stage, twelve teams (top three teams in each group) would play the play-off.

The play-off stage was played as two-legged ties of two teams each. The away goals rule, an extra time (away goals rule is not applied for the scores in the extra time), and a penalty shoot-out were used if needed.

Prime stage (Knockout stage) 
The prime stage (knockout stage) was played by 8 teams who advanced to ACL group stage and won the play-off stage.

The quarter-finals and the semi-finals were played as two-legged ties (same as the play-off stage). The final was a single game.

The video assistant referee (VAR) system would be used during this stage.

Regulation changes
Due to the COVID-19 pandemic, the extraordinary board held a meeting on 5 June 2020 to change the tournament method as follows:
 The U-21 starting rules (including one or more Japanese nationals aged 21 or younger on 31 December 2020 as starters) are not applied to all matches.
 The group stage was changed from the previous "Double round-robin" (six games for each team) to "Single round-robin" (three games for each team), with the combination as it was. The results of matchday 1 of the group stage remained valid.
 The playoff stage was cancelled, and the best runners-up along with four group winners advanced to the prime stage.
 In the prime stage, 8 clubs compete in a one-leg knockout tournament. In addition, extra time will not be played except for the final, instead the match goes straight to penalty shoot-out to determine the winners if tied after 90 minutes in the quarter-finals and semi-finals.

On 23 June, J.League announced that it would not use the video assistant referee (VAR) system.
