The was the fourteenth season of the Japan Football League, the third tier of the Japanese football league system. It has started on March 11, and finished on November 18.
The league intended to run the season in the usual 18-team format, but after the withdrawal of Arte Takasaki in January no replacement team was invited so in 2012 JFL features only 17 teams.
Subsequently, only one club will be directly relegated and one take part in pro/rele playoffs to bring the number of JFL clubs back to 18.
During the season, on 23 July, Nagano Parceiro were approved as J. League associate members, though they are not eligible for promotion until the completion of the renovation of their home stadium which is expected in 2016.
On 28 September 2012, J. League Organization made an announcement for club licenses for 2013, and only Nagasaki was granted conditional J2 license.
On 16 October 2012, it was reported that Sagawa Shiga F.C. had notified JFL organization about their intention of withdrawal from JFL as of the end of this season. On 17 October 2012, JFL Committee has approved the request from Sagawa Shiga F.C. for its withdrawal from JFL as of the end of the season.
Because of withdrawals by Arte Takasaki and Sagawa Shiga, no clubs will be relegated automatically as of the end of the season. The bottom finished (17th placed) club will play a play-off against the 3rd placed club of the 2012 Regional League promotion series.
