## Competition rules

In January 2017, the JRFU announced the format of the Top Challenge League competition. The competition was played in two stages. The First Stage was a round-robin format, where all eight teams played each other once.
The top four teams in the First Stage progressed to Group A of the Second Stage, while the bottom four teams progressed to Group B. Each of these groups was another round-robin, with all four teams playing each other once.
The four teams that competed in Group A progressed to promotion play-offs against the bottom four teams in the 2018–19 Top League.
The two team that finished bottom and second-bottom of Group B progressed to the relegation play-offs, along with the winners and the runners-up of the Regional Challenge, held between the champions of the Top East League, Top West League and Top Kyūshū League.
