After showing great form for Japan's youth teams, on May 24 2019, Ueda was called up by Japan's head coach Hajime Moriyasu to feature in the Copa América played in Brazil. At the time of his call-up, he was still playing for his university team, the first time a university player was called up since Kensuke Nagai and Kazuya Yamamura were selected in 2010. He made his debut on 17 June 2019 in a 4-0 defeat against Chile, as a starter. He went on to make two more appearances as a substitute in the competition, before Japan were knocked out at the group stage with Ueda missing some big chances throughout.
