Overview

This season was the first to feature promotion/relegation from the Japan Football League, enabling the possibility for teams to be relegated from the J3. The system of promotion/relegation between the leagues can be determined by the eligibility of the JFL's champions and runners-up for the season.- If only the JFL champions holds a license, there will be automatic promotion/relegation with the J3's 20th-placed team.
- If only the JFL runners-up holds a license, there will be promotion/relegation play-offs with the J3's 20th-placed team.
- If both the JFL champions and runners-up hold a license, there will be automatic promotion/relegation between the JFL champions and the J3's 20th-placed team, and promotion/relegation play-offs with the J3's 19th-placed team.
- If both the JFL champions and runners-up do not hold a license, no promotion/relegation between J3 and JFL will take place.
