[5] The system of promotion/relegation between the leagues can be determined by the eligibility (Promotion to J3 requires a J.League license) of the JFL's champions and runners-up for the season.
No changes were made from the previous season: The dates and the host teams of the promotion/relegation play-off were pre-determined by the J.League.
In case it happens: It will be played in two legs on 1 and 7 December, with the J3 team hosting the second leg; away-goals rule will not be applied; should the match be tied, it will require extra-time, and if the draw persists, penalty shoot-outs.
[11] The teams which possess (or are applicants of) promotion-enabler licenses are highlighted in green in the following table.
If the two teams were equal on the scoreboard, the match would go to extra time and penalties.
