There were two teams relegated last season to the 2023 J2 League. Shimizu S-Pulse and Júbilo Iwata, both from Shizuoka Prefecture, were relegated due to them finishing 17th and 18th respectively the previous season. Thus, this is the first Japanese top-flight season to not feature any team from the region.

Kyoto Sanga finished on 16th place, but won the promotion/relegation playoffs against Roasso Kumamoto and thus retained their top league status. Had Roasso won, it would have been their first ever promotion to the top-flight.

Two teams were promoted from the 2022 J2 League: Albirex Niigata, who won the title and returned to J1 after a five-year absence, and Yokohama FC, who finished second, returning to the J1 after just a season playing on the J2 League.
