The was the 34th season of the main competition for under-18 teams in Japan, the 13th after rebranding the competition to the current "Premier League" format, and the 2nd season with 24 clubs participating in the league.
The Premier League/Prince League play-offs gives an opportunity for teams to be promoted from the Prince Leagues (a conglomerate of regional leagues that forms the 2nd division of youth football in Japan). The two 10th-placed teams in their respective 2022 Premier League divisions participated in the play-offs, while the 11th and 12th-placed teams of each division were directly relegated. So, it not only determined the newcomers but also determined whether there will be other relegated teams from the Premier League or not.
On 2022, the number of teams that could make the jump to the top division were from four up to six.
As usual, the teams were allocated to each division by the JFA based on geographical positions. Yokohama FC U-18s was the only team to be relocated, switching from the East to the West on 2023.
Qualified for the stage the 16 top-ranked teams of the nine Prince League divisions, with each region having its amount of qualifying slots predetermined by the JFA. They were divided into four blocks, with their respective block winners (highlighted in bold) qualifying for the next season's Premier League.
