The Japanese Regional Football League Competition (全国地域サッカーチャンピオンズリーグ, Zenkoku Chiiki Sakkā Championzu Rīgu) is a nationwide play-off tournament meant as a transition for Japanese football clubs competing in regional leagues to the top tier for amateur clubs, the Japan Football League.
Until 1976, the main entrance route for regional clubs to the Japan Soccer League was the All Japan Senior Football Championship, a cup competition. In 1977, to test clubs in a league environment before entrance to the league, the Japan Football Association devised this tournament.
In 1984 and 1985 more promotion places were added due to the JSL, expanding its divisions. In 1992 it began promoting clubs to the former JFL's second division and, from 1994 to 1998, to its single division. In 1999 and 2000 it added extra promotion places due to the formation and expansion of the new JFL.
Yamaha Motors (Júbilo Iwata) are, thus far, the only Regional Series champions to later become First Division champions. They are also the only club to retain the title, as they failed to be promoted in their first attempt due to losing a playoff series. Since 1980 every champion has been automatically promoted, exceptions being made at the champion's request in 1993 (Nippon Denso/FC Kariya) and 2002 (Ain Foods) as they lacked the resources to compete at the national level.
Until 2009, the number of places in the tournament was 16, distributed as follows:
As of 2010, the regional league runners-up are no longer eligible and the university association is no longer allowed to make recommendations, reducing the number of places to 12.
