The, officially the 2023 All Japan Adults Football Tournament, and most known as the 2023 Shakaijin Cup,[1] was the 59th edition of the annually contested single-elimination tournament (or cup) for the best-ranked amateur clubs in Japan. As it's restricted to non-league clubs (Participating on Regional or Prefectural Leagues; not included in the nation-wide league competitions), the defending champions, Briobecca Urayasu, could not defend their title as they are playing the 2023 season in the Japan Football League, Japan's 4th-tier league. All the matches were streamed in the "Shakaijin Cup" channel.
Every match at the tournament was played with 40 minutes per half, instead of the usual 45, with every match being played under 80 minutes of action in total, excluding added time. The match would go directly to a penalty shoot-out, if a winner was not decided after the full-time whistle. Up to five substitutions in three or less substitution breaks (excluding half-time) were allowed at the tournament, as per FIFA recommendation.[2]
The top three teams qualified to play on the 2023 edition of the Japanese Regional Champions League, which serves as Japan Football League's play-off tournament. However, the top three teams do not necessarily mean the semi-finalists. Instead, it refers to the best-ranked teams in the "Shakaijin" among those that have not finished as champions of their respective Regional Leagues.
About individual suspensions, players or officials should be suspended for an upcoming fixture if they: Receive a yellow card in two consecutive matches; receive a red card. Also, accumulated yellow cards would be reset to zero after the quarter-finals.
Regional champions who were at the time already qualified for the Regional Champions League are denoted in bold. Teams from the 6th tier or below can not participate in the Regional Champions League and are denoted in italics.
