Clubs
For the first time since 2012, 17 clubs have taken part in the JFL season. Last year no relegations were in place in J3, the league had the intent of seeing two more teams joining from the start, but only Tegevajaro Miyazaki got promoted with one game to play and joined J3 for the 2021 season. That’s because Verspah Oita, who won the JFL for the first time in their history, were not promoted as they did not hold a J3 license, while Sony Sendai and Honda FC, who finished 3rd and 4th respectively, also didn’t hold a J3 license.FC Tiamo Hirakata and FC Kariya won promotion to the JFL by qualifying in the top two spots of the 44th Regional Pro Series. For the Hirataka-based side it was the first time in JFL, but Kariya are back after a twelve-year long hiatus.
There are six teams eligible for promotion with J3 licenses; these are highlighted in green in the following table.
