The 2022 J3 League, referred to as the 2022 Meiji Yasuda J3 League (Japanese: 2022 明治安田生命J3リーグ, Hepburn: 2022 Meiji Yasuda Seimei J3 Rīgu) for sponsorship reasons, was the 9th season of J3 League under its current name.
Iwaki FC won the J3 title for the first time in their history, in their debut campaign at the J3 League, just a year after being promoted from the JFL. They were promoted to the 2023 J2 League alongside Fujieda MYFC, who narrowly promoted with one point off the 3rd-placed team. Both teams won promotion for the J2 League for the first time.
