A total of 134 teams competed, split into 9 groups, in the Japanese Regional Leagues, the fifth tier of the Japanese association football league system, in 2020. Due to the COVID-19 pandemic in Japan, all matches in all regions were changed from double round-robin into single round-robin, except Chūgoku and Tōkai.
All regional champions qualified for the Japanese Regional Football Champions League. Like the J.League, there was no relegation in this season to Prefectural Leagues (promotion and relegation between divisions were still available for some regions).
