The 2020 J1 League, also known as the 2020 Meiji Yasuda J1 League (Japanese: 2020 明治安田生命J1リーグ, Hepburn: 2020 Meiji Yasuda Seimei J1 Rīgu) for sponsorship reasons, was the 28th season of the J1 League, the top Japanese professional league for association football clubs, since its establishment in 1992. This was sixth season of J1 League as renamed from J. League Division 1. The league began on 21 February and eventually ended on 19 December 2020. The league was planned to have a season break to avoid clashing with the 2020 Summer Olympics,[2] but the Olympics were postponed due to the COVID-19 pandemic in Japan.[3]
Yokohama F. Marinos were the defending champions while Kashiwa Reysol and Yokohama FC entered the league as promoted teams from the 2019 J2 League, replacing Júbilo Iwata and Matsumoto Yamaga who were relegated to the 2020 J2 League.
