However, on 6 May, they lost their continental participation spot as Urawa Red Diamonds won the 2022 AFC Champions League.

Emperor's Cup
As a J1 League club, it started in the 2nd round of the competition. Sanfrecce was the runner-up of the competition in the previous season.

J.League Cup
As every other club, Sanfrecce starts the competition at the group stage. The club will play the season as the defending champions, after they won past Cerezo Osaka in the 2022 J.League Cup Final by a 2–1 win, which was earned with a last-minute comeback.
