2023 Japanese Regional Football Champions League

The 2023 Japanese Regional Football Champions League (全国地域サッカーチャンピオンズリーグ2023) is the 47th edition of the referred annually contested cup for the best-placed teams of each of their respective Regional Leagues, and of the 2023 Shakaijin Cup. Promoted to the JFL, the club couldn't defend their title. Briobecca Urayasu are the title holders, as they won the championship at the final round. Currently playing in the Japan Football League, they are unable to defend their title.

Format
As usual, 12 teams will participate in the transitional tournament for regional league teams who want to join the JFL. Nine qualifies as champions of their respective Regional Leagues on 2023. The other three spots are by default allocated to the best three Shakaijin Cup teams out of its semi-finalists that were not yet qualified to the Champions League via the Regional Leagues (being placed below the champions of their league).

In case the slot (s) can't be filled, in a situation where more than one semi-finalist has already qualified to the Champions League as Regional champions, the empty slot (s) is rewarded to the J.League 100 Year Plan club status holders that finished the season as a Regional League runner (s)-up. If more than one "status holders" finishes the season as the 2nd-placed team in their respective Regional Leagues, an annually-rotated order of priority will be taken into consideration. This year, the order is: Tohoku, Shikoku and Kanto. Tohoku and Shikoku's runners-up Cobaltore Onagawa and Lvnirosso NC are not "status holders". The slot was then assigned to Kanto's runners-up Tochigi City FC, the only status holder out of the three.

Only teams that want to join the JFL can be promoted. If a team with no intention to join the JFL ends up winning the final round, the promotion spot will be allocated to the runner-up. If the runner-up also have no intention to be promoted, a spot will be allocated to the third-placed team. If they also refuse, the bottom-placed team will be promoted instead. In all mentioned scenarios, the bottom-placed team of the 2023 Japan Football League will not be relegated, and no play-off will be held. If both Regional Champions League winner and runner-up aims to be promoted, the winner will be automatically promoted, whereas the runner-up will hold a play-off match with JFL's bottom-placed team.

Depending on the clubs that ended up as the top three teams in the Shakaijin Cup, a specific rank that would take the J.League 100 Year Plan club status clubs and its performances in the 2023 Regional Leagues into account would be applied to determine the final teams on this competition.
