Ahead of the 2019 season, Uchida was appointed as the new Kashima Antlers’ captain following the departure of Gen Shoji. His first match as captain came on 1 March 2019 against Kawasaki Frontale and set up an equalising goal for Sho Ito, in a 1–1 draw. He later captained three more matches between 9 March 2019 and 30 March 2019. However, during a 3–2 win against Júbilo Iwata on 30 March 2019, Uchida suffered a knee injury and was substituted that kept him out for several months. On 14 August 2019, he made his return from injury, coming on as a late substitute, in a 4–0 win against Tochigi SC in the third round of the Emperor's Cup. Since returning from injury, Uchida resumed his captaincy role despite being placed on the substitute bench in a number of matches for the rest of the 2019 season. Kashima Antlers went on to finish third place in the league. At the end of the 2019 season, he went on to make twelve appearances in all competitions.
