Due to a ban imposed by FIFA, after an illegal breach of contract between Fabián González and an unnamed Thai club, Júbilo is unable to make any new signings from outside of the 2022 club system during both transfer windows of the 2023 season. Players out on loan can normally return to the club, and free transfers are allowed.[2]Tokyo International University graduate Shu Morooka was scheduled to join Júbilo for the 2023 season, but as the club received a transfer ban, his provisional contract with Júbilo was cancelled, and he later joined Kashima Antlers.[3][4] The club filed an appeal about the CAS decision over the subject, but it was denied.[5]
